What is the use of HCL acid in the digestive system process?I'm doing and science project, i have to pretend i'm a hamburger and somebody just ate me and I'm going through their body. So my teacher gave use a list of words we have to use and write a story about it. One of the words is HCL acid, but I can't figure out what its purpose is in the digestive process. Help!?

acid in the stomach is HCL. It is released by the pareital cells in the stomach. I spelled that wrong u gotta look up these cells. The hydro cloric acid functions to kill some bacteria in food and to denature proteins. Protein is made up of a long chain of amino acids. It is curled up in like a ball in structure. When the protein is denatured, this protein ball straightens up in a line. This allows enzymes to break bonds (break up the proteins).

The HCl in the stomach is produced to lower the pH; pepsin (the protease produced by the stomach) will not digest proteins properly unless the pH is around 1.5-2.
