Question

what is the role of HCL in protein digestion?

Answer 1

The primary role of hydrochloric acidis to sterilize the food you eat and to prevent harmful bacteria from entering the GI tract. HCL also triggers the release of enzymes such as pepsin which are essential for the digestionofprotein.

Answer 2

hydrochloric acid -- a main component of stomach acid -- is extremely important. One of its roles in keeping you healthy is protein digestion. Everything you eat must be broken down by digestive enzymes in order to be absorbed, but protein is the only nutrient that needs to be prepared by hydrochloric acid before your stomach's naturally occurring enzymes can work properly.
