To break down proteins in food

Explanation: proteins ingested into the body have to be broken down into free amino acids that can be absorbed in the body.these is carried out by the enzyme proteases.

Hcl provides an optimum pH for the activities of proteases in the stomach.

It also help to activate pepsinogen into pepsin

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
