Hydrolysis rate of starch
WebNo, not that easy. Hydrolysis of polysaccharides is not spontaneous and favorable process. In starch (or any other kind of polysaccharide) two glucose monomers are bonded via a … WebStarch is a polymer composed of a series of glucose monomers. Amylase hydrolyzes starch into glucose and disaccharide maltose (Lab pg62). The lock and key theory is a possible explanation of why, only one type of enzyme can breakdown starch.

The increase in the … WebOne of these hydrolytic enzymes is α-amylase from Bacillus licheniformis, which is often used for large-scale starch hydrolysis (see Figure 1). Enzymatic treatment of starch with α-amylase is usually preceded by gelatinisation. Gelatinisation of starch is required to increase the accessibility of the substrate and to enhance the hydrolysis rate.
