A gastric gland is a tubular structure in the vertebrate stomach that
secretes gastric juices. The gastric glands have three types of cells that secrete
different components of the gastric juice. One of them is being a chief cell, which
is a rust color and is an inactive form of the digestive enzyme Pepsin. Pepsin
begins the digestion of proteins in food. Pepsin is a Peptidases, which is an
enzyme that breaks peptide bonds of proteins.
Pepsin is found in the mucosal lining of the stomach that breaks down
the protein in the food we eat. A protein is an organic compound that consists of
aminio acids joined by peptide bonds. Pepsin is one of three principal protein-
degrading enzymes in the digestive system the other two being chymotrypsin
which catalyzes the hydrolysis of peptide bonds and trypsin that acts with the
other proteins to break down dietary protein molecules to their peptides and
amino acids which will be absorbed by the......
