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.
