What is an example of a proteolytic (protein dissolving) chemical?

Proteolytic chemicals are substances that break down proteins through the process of hydrolysis. Enzymes are biological catalysts that facilitate and speed up biochemical reactions, including the breakdown of proteins. They can be classified as proteolytic if they specifically attack peptide bonds within proteins, leading to protein dissolution.

In a medical aesthetic context, enzymes such as papain (derived from papaya) and bromelain (derived from pineapple) are examples of proteolytic enzymes used in treatments to exfoliate and break down proteins in the skin, which can aid in reducing the appearance of fine lines and uneven texture.

The other options, while beneficial in the context of skin care, do not primarily serve as proteolytic agents. Salicylic acid is a beta-hydroxy acid that primarily works as an exfoliant for the skin's surface and is effective in treating acne. Glycolic acid is an alpha-hydroxy acid that exfoliates by loosening the bonds between dead skin cells, promoting cell turnover rather than specifically breaking down proteins. Retinoids are derivatives of vitamin A that promote cell turnover and reduce signs of aging but do not function as proteolytic agents. Thus, the choice of enzyme as a proteolytic chemical is accurate and
