WebIntroduction: Alpha-amylase (EC 3.2.1.1) is the most abundant enzyme in the saliva of man and of several vertebrates. In humans, salivary amylase is mainly formed in the parotid gland; its activity is of high inter-individual and intra-individual variability. The physiological functions of α-amylase have not yet been explored completely. WebA higher temperature generally makes for higher rates of reaction, enzyme-catalyzed or otherwise.
