Optimal conditions for amylase activity

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. WebFeb 1, 2000 · 3.2 Effect of pH, temperature and salt concentration on amylase activity. The enzyme exhibited an optimal activity at pH 7.0, and was relatively stable in alkaline conditions with at least 40% of the activity at pH 10.0 ().In contrast, the activity sharply decreased in acidic conditions with more than 90% of the activity lost between pH 5.0 and …
