THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Pepsin is an aspartic protease that acts in food digestion in the mammal stomach. An optimal pH of around 2 allows pepsin to operate in its natural acidic environment, while at neutral pH the protein is denatured.

Detailed explanation-2: -For example, some enzymes work best at acidic pHs, while others work best in neutral environments. Digestive enzymes secreted in the acidic environment (low pH) of the stomach help break down proteins into smaller molecules. The main digestive enzyme in the stomach is pepsin, which works best at a pH of about 1.5.

Detailed explanation-3: -It’s highly acidic and helps break down food for easier digestion. This helps your body absorb nutrients more easily as food moves through your digestive tract. In order to break down everything from meat to tough, fibrous plants, stomach acid has to be highly acidic.

Detailed explanation-4: -In the stomach, for instance, digestive enzymes (such as pepsin which breaks down proteins) are adapted to function in very acidic environments (pH 1.5-2).
