Carbohydrolytic

Glucoamylase

An exo-acting amylase that hydrolyzes α-1,4 and α-1,6-glycosidic linkages from the non-reducing ends of starch and dextrins, liberating free glucose molecules. By complementing the action of α-amylase, glucoamylase ensures that partially digested starches are fully converted into glucose. This provides a complete saccharification step, important for maximizing carbohydrate utilization in the diet.*

BIOCHEMICAL ROLE IN DIGESTION

Glucoamylase catalyzes the sequential removal of glucose units from the non-reducing ends of starch, dextrins, and maltose by hydrolyzing both α-1,4 and α-1,6 glycosidic linkages. This activity complements amylase by ensuring that partially degraded starch is fully reduced to glucose, the only form of carbohydrate that can be directly absorbed into circulation. Its ability to act on branched points makes it essential for complete utilization of complex carbohydrates, particularly in diets containing amylopectin-rich foods.*

NUTRITIONAL RELEVANCE IN SUPPLEMENTATION

Supplemental glucoamylase strengthens the body’s ability to achieve full carbohydrate hydrolysis, ensuring no energy is lost in the form of partially digested saccharides. This can be particularly beneficial for individuals consuming diets high in refined starches or resistant starch, where digestive efficiency is often challenged. Glucoamylase helps stabilize postprandial energy supply, reduces the likelihood of intestinal fermentation, and enhances the overall metabolic value of carbohydrate-rich meals.*
