Carbohydrates such as sugars and starch are the primary source of energy in cereals and defatted protein crops. Carbohydrases like α-amylase enzymes catalyze the breakdown of carbohydrates.
Alpha-amylase hydrolyzes the linear chain of amylose, breaking the α-1,4 glycosidic bonds in starch. Monogastric animals typically digest around 90% of available starch. Exogenous amylases may be used to increase the energy value of raw materials.
