The enzyme amylase belongs to the class

(a) hydrolase                        (b) isomerase

(c) transferase                      (d) lyases

(a) Amylases forms a class of enzymes that split or hydrolyse starch. Those found in animals are called α-amylases while those found in plants are termed as β-amylases. α-amylase hydrolyses starch to maltose and other products and is found in vertebrate saliva and intestine. β-amylase hydrolysis starch to maltose but by different process. Pancreatic amylase is amylopsin. Salivary amylase is ptyalin.
