Peptide vs. Pepsin: What's the Difference?

Any of various natural or synthetic compounds containing two or more amino acids joined by peptide bonds that link the carboxyl group of one amino acid to the amino group of another.

A digestive enzyme found in gastric juice that catalyzes the breakdown of protein to peptides.

(organic compound) Any of a class of organic compounds consisting of various numbers of amino acids in which the amine of one is reacted with the carboxylic acid of the next to form an amide bond.

A substance containing pepsin, obtained from the stomachs of hogs and calves and used as a digestive aid.

(chemistry) The peptide bond itself.

(enzyme) A digestive enzyme that chemically digests, or breaks down, proteins into shorter chains of amino acids.

Amide combining the amino group of one amino acid with the carboxyl group of another; usually obtained by partial hydrolysis of protein

A proteolytic enzyme (MW 34,500) contained in the secretory glands of the stomach. In the gastric juice it is united with dilute hydrochloric acid (0.2 per cent, approximately) and the two together constitute the active portion of the digestive fluid. It degrades proteins to proteoses and peptides, and is notable for having a very low pH optimum for its activity. It is the active agent in the gastric juice of all animals.

An enzyme produced in the stomach that splits proteins into peptones
