Mention the function of salivary amylase,pepsin,lipase and trypsin

Function of salivary amylase:

• Saliva secreted into the buccal cavity contains electrolytes such as Na⁺, K⁺, Cl⁻, HCO₃^-and enzymes such as salivary amylase and lysozyme.
• The hydrolytic action of salivary amylase hydrolyses starch into maltose.

Function of pepsin:

• Pepsin hydrolyses proteins into proteoses and peptones (peptides).

Function of lipase:

• Gastric lipases are secreted in very small amounts. They bring about mild hydrolysis of fats into fatty acids and glycerol.
• Pancreatic lipases break down fat micelles into diglycerides first and then monoglycerides.
• Intestinal lipases act on monoglycerides and break them down into fatty acids and glycerol.

Function of trypsin:

• Trypsin along with chymotrypsin and carboxypeptidase act on partially digested proteins (proteins, peptones and proteoses) in the stomach and convert them into dipeptides.
