What is an example of a proteolytic chemical?

A proteolytic chemical is one that breaks down proteins into smaller peptides or amino acids. Enzymes are biological catalysts that speed up chemical reactions, and proteolytic enzymes, specifically known as proteases or peptidases, facilitate the process of protein degradation. These enzymes play essential roles in various biological processes, including digestion, where they help break down dietary proteins into amino acids for absorption.

For instance, the enzyme pepsin, which is activated in the stomach, breaks down proteins from food into smaller peptides, allowing the body to utilize these nutrients effectively. This characteristic makes enzymes, particularly proteolytic enzymes, crucial in both physiological and biochemical contexts.

The other options do not possess this proteolytic activity. Alcohol does not act to break down proteins, sugars serve as carbohydrates and provide energy rather than having a proteolytic function, and salt primarily acts as a preservative and flavoring agent without directly breaking down proteins.
