Invertase is an enzyme. It is commonly called "invert sugar" or "inverted sugar syrup. Chemists during the s were studying the effect of yeast on sugar and realized that before the sugar began fermenting, it changed form.

After much research, the chemists isolated the enzyme that caused this: invertase. By the yearthe process for deriving invertase from yeast was commonly used. Over the course of the next 20 plus years, chemists found many uses for invertase, most importantly in candy-making. When invertase is added to sugar candy recipes, like fondant candy fillings, it gradually liquefies the fondant.

This is one way of producing the liquid center in candies like cherry cordials. The reaction takes a few days to occur, so there is a waiting period when making liquid centers with invertase. This enzyme also makes fondant appear smoother.

Although it sounds like something made in a lab, invertase is a part of many different natural processes. Besides bees, we actually have our own supply of invertase as part of our saliva. The exact amount of invertase needed depends on many factors. These include the strength and preparation of the invertase, the temperature of the environment, and the recipe itself.

Once you make your candy creation, the invertase needs time to break down the sucrose and turn it into liquid. If you are using it for candy making purposes, plan ahead.

The invertase needs a few days to at least a week in storage to make the solid turn into a liquid. There are not really any known substitutions for invertase.

Depending on what you are making, there may be some workaround solutions.Roitsch, M. Balibrea, M. Hofmann, R. Proels, A. Extracellular invertase is the key enzyme of an apoplasmic phloem unloading pathway and catalyses the hydrolytic cleavage of the transport sugar sucrose released into the apoplast.

The regulation of extracellular invertase by all classes of phytohormones indicates an essential link between the molecular mechanism of phytohormone action and primary metabolism. Carbohydrate partitioning between the autotrophic source tissues and a variable number of sink tissues competing for a common pool of carbohydrates is a highly dynamic process that accompanies all stages of growth and development of higher plants.

This physiological mosaic is also known to be affected by exogenous factors such as pathogen infection or abiotic stress stimuli that require fast induction of sink metabolism for the ability to activate a cascade of defence responses and to mediate physiological adaptations.

For these reasons, the enzymes responsible for the first metabolic reaction of sucrose are probably critical links between photosynthate production in source leaves and growth capacity of sink organs Farrar, ; Balibrea et al.

The resulting hexose monomers are then imported into the sink cell by monosaccharide transporters. Supplying carbohydrates via an apoplasmic phloem unloading pathway provides a mechanism for flexible and fast adjustment of the carbohydrate supply according to wide variations in demand. The tremendously large surface area of the total apoplasmic space surrounding all sink cells provides the possibility to allow very high uptake rates if required.

Extracellular invertase is particularly suited as a key regulator of apoplasmic phloem unloading due to its enzymological properties. In addition, extracellular invertase catalyses the only irreversible step of the apoplasmic phloem unloading pathway. Accordingly, a large number of stimuli have been identified that affect the mRNA levels of specific isoenzymes. The evolution of such a variety of regulatory mechanisms further supports the key role of extracellular invertase for assimilate partitioning.


Since the physiological relevance of extracellular sucrose cleavage has been addressed by molecular approaches Sturm and Chrispeels, ; von Schaewen et al. Progress is rapid in the field and this review focuses on recent advances and addresses specific aspects of the transcriptional regulation of genes encoding extracellular invertases and the underlying signal transduction pathways.

The essential function in sink tissues is evident from transgenic approaches on isogenes that are specifically expressed in distinct flower organs Goetz et al.

The regulation by all classes of phytohormones indicates that extracellular invertases are involved in mediating the corresponding hormone responses. The induction of extracellular invertase by both abiotic and biotic stress stimuli supports the suggestion that extracellular invertase is not only a key modulator of assimilate partitioning, but is also an important component of various stress responses. An expression of extracellular invertases in floral organs has been reported for different plant species, namely carrot Lorentz et al.The activity of yeast invertase as a function of oxidation-reduction potential has been investigated using a large number of oxidants and reductants.

The inhibiting action of strong oxidants is upon the enzyme rather than on the substrate and appears to be essentially irreversible Experiments indicate that the inhibiting action of strong oxidants on invertase is primarily related to their high oxidation-reduction potential rather than to a specific toxic action unrelated to E h.

The effects of oxidation-reduction potential upon invertase activity are independent of the purity of the enzyme, since they are the same for commercial invertases, fresh bakers' yeast, powdered bakers' yeast, brewers' yeast, and highly purified invertase.

Possible mechanisms involved in the inactivation of invertase by oxidants are discussed. These references are in PubMed. This may not be the complete list of references from this article.

The role invertase plays in the digestion process is that it separates sucrose or table sugar into glucose and fructose.

When sucrose is broken down to glucose and fructose it can be used by the body for energy and also helps overall digestion of starch and carbohydrates as well. Invertase occurs naturally in our bodies but can also be found in bee pollen and yeasts.

Besides the vital role invertase plays in our overall digestive health, invertase also helps with human disease prevention, anti-ageing processes and physical rejuvenation. Essential enzymes play a bigger part in our overall health than we know.

Extracellular invertase: key metabolic enzyme and PR protein

When our body is getting the nutrition it needs from the foods we ingest, our whole system prospers. One drawback of getting older is that our body produces less and less essential enzymes like invertase. The less invertase in our body, the more likely the improper digestion of sugars and carbohydrates occur.

This leads to digestive issues like gas, acid reflux and upset stomach. The longer a person goes without knowing their enzyme levels, the more of a strain they put on their digestive system and other enzymes that are producing at a good rate.

There are many benefits that go with the supplementation of invertase, mainly the immune boost and antioxidant support. One of the positive side effects of enzyme supplementations is the boosts given to other areas of our system. The more there is an enzyme to breakdown the nutrients and have your body absorb, the more likely your health will be at optimal levels. Invertase, just like all the other essential enzymes is crucial for a healthy digestive system and a healthy body as well.

Knowing things like the different enzyme levels in your body on a yearly basis will help ensure your digestive health is good. Furthermore, finding the right blend of enzymes that will help digest the endless amounts of foods and ingredients available today will get you feeling better about yourself and looking it too.

If you decide to supplement your body with certain enzymes, it is very important to choose a product that has very pure ingredients and will show results.

This mechanism contributes to long-distance assimilate transport, provides the substrate to sustain heterotrophic growth and generates metabolic signals known to effect various processes of primary metabolism and defence responses. The essential function of extracellular invertase for supplying carbohydrates to sink organs was demonstrated by the finding that antisense repression of an anther-specific isoenzyme provides an efficient method for metabolic engineering of male sterility.

The regulation of extracellular invertase by all classes of phytohormones indicates an essential link between the molecular mechanism of phytohormone action and primary metabolism.

The Health Benefits of Invertase

The up-regulation of extracellular invertase appears to be a common response to various biotic and abiotic stress-related stimuli such as pathogen infection and salt stress, in addition to specific stress-related reactions. Sucrose derivatives not synthesized by higher plants, such as turanose, were shown to elicit responses distinctly different from metabolizable sugars and are rather perceived as stress-related stimuli.

Abstract Extracellular invertase is the key enzyme of an apoplasmic phloem unloading pathway and catalyses the hydrolytic cleavage of the transport sugar sucrose released into the apoplast. Publication types Research Support, Non-U. Gov't Review.Invertase is an enzyme that catalyzes the hydrolysis breakdown of sucrose table sugar into fructose and glucose. The resulting mixture of fructose and glucose is called inverted sugar syrup.

Related to invertases are sucrases. Invertases and sucrases hydrolyze sucrose to give the same mixture of glucose and fructose. Invertases cleave the O-C fructose bond, whereas the sucrases cleave the O-C glucose bond. For industrial use, invertase is usually derived from yeast. It is also synthesized by bees, which use it to make honey from nectar. Invertase is expensive, so it may be preferable to make fructose from glucose using glucose isomeraseinstead. Chocolate-covered cherries, [4] other cordials, and fondant candies include invertase, which liquefies the sugar.

Once the candy is manufactured, it needs at least a few days to a few weeks in storage so the invertase has time to break down the sucrose. Urea acts as a non-competitive inhibitor of invertase, presumably by breaking the intramolecular hydrogen bonds contributing to the tertiary structure of the enzyme.

You can feel confident in knowing that the information within this article is sound. Invertase is a carbohydrate-digesting enzyme that splits sucrose common table sugar into its component parts, glucose and fructose. It is generally derived from a beneficial strain of Saccharomyces cerevisiae and then purified to be used either by itself or as a part of a multi-enzyme formula.

Combined with other carbohydrates, it enhances the overall digestion of starch, sugar and other carbohydrates. Invertase's ability to break down hydrolyze the bond between fructose and glucose makes it a vital part of the digestion of complex sugars into blood sugar glucose which can be used as a ready fuel source by the body.

It is also known as beta-fructofuranosidase and may be listed under this name on some product labels and scientific literature.

invertase enzyme function

Invertase is one of the essential enzymes nature uses to help us digest sugars. Commonly found in bee pollen and yeast sources, invertase plays a key role not only in digestive processes, but also, and perhaps more importantly, in overall human disease prevention, physical rejuvenation and anti-ageing processes.

As we age, we have less access to this natural enzyme, resulting in a reduced ability to extract the vital nutrients from the food we eat.

It can also slow our digestive process, as sugars and starches are such a big part of most American diets. And, while some forms of sugar and carbohydrates are good for the body, they cannot be absorbed or digested well without the help of the invertase enzyme. It is also created naturally by bees, who use its ability to hydrolyze the sugars in raw nectar to create the delicious honey that we eat. Honeybees produce massive amounts of the enzyme as it breaks the bond between glucose and fructose, adding hydrogen and hydroxide.

In contrast to many other enzymes, invertase has the distinct ability to remain active within a wide range of pH levels. Enzymes found in honeysuch as invertase have been studied for their metabolic activity. Studies done on asparagus Asparagus officinalis found that high invertase activity found in the top portion of asparagus spears might be related to the high metabolism occurring in this portion.

Invertase has many antioxidant properties, and it is a powerful agent against harmful organisms. These two aspects allow it to aid in the defense against of bacterial infestations and gut fermentation due to oxidation. In Ancient India, raw honey was often used in patients with a weak heart. It was known to kill off bacteria and reduce intestinal ailments. It was also used for its hygroscopic moisture-retaining properties, and its ability to pull moisture out of the body, causing bacterial infestations to subside.

Invertase is one of these key elements of the enzymatic support found in honey. Because invertase creates pre-digested simple sugars, it helps reduce stomach toxicity, in that sugars do not remain in the stomach long enough to create toxic fermentation.

Fermentation is what causes bacteria and disease to build up in the digestive tract. In this way, invertase helps protect the body from ulcers, as well as many other digestive diseases. Again, in honey, enzymes such as invertase show the ability to turn glucose into natural hydrogen peroxide.

Enzymes including invertase have been shown to help reduce coldsflu and other respiratory infections. One European study on 18, patients found that honey drastically helped upper respiratory tract infections such as bronchitis, asthma and allergies. Some medicinal studies also show that the invertase enzyme may exhibit some chemotherapeutic properties. Research done in Australia and Japan have found that the enzymes in honey helped support patients with advanced cases of both bone and stomach cancer.

In some cases, the cancers even went into regression. Currently, enzyme therapy is being used as a vital component of many natural cancer therapies.
