Pepsin Pepsin. Definition. noun, plural: pepsins or pepsine. A proteolytic enzyme in the gastric juice of birds, reptiles, fish, and mammals that partially digest dietary proteins into simpler, shorter chains of amino acids such as proteoses and peptones in the presence of hydrochloric acid. Supplement.Pepsin is capable of digesting many proteins from the food except protamine, keratin, and other highly glycosylated proteins. It is converted from pepsinogen that is released from the gastic pits of the stomach.The conversion of pepsinogen into pepsin occurs in the presence of hydrochloric acid or by the action of another pepsin in the gastric juice. Word origin: Greek pepsis (digestion), from peptein (to digest). Related term(s): 1  Propepsin.2  Peptic.upplement. Pepsin is capable of digesting many proteins from the food except protamine, keratin, and other highly glycosylated proteins. It is converted from pepsinogen that is released from the gastic pits of the stomach.

pepsin /pep·sin/ (pep´sin) the proteolytic enzyme of gastric juice which catalyzes the hydrolysis of native or denatured proteins to form a mixture of polypeptides; it is formed from pepsinogen in the presence of acid or, autocatalytically, in the presence of pepsin.

pepsin pepsin. a proteolytic enzyme that is the principal digestive component of gastric juice. It acts as a catalyst in the chemical breakdown of protein to form a mixture of polypeptides; it is formed from pepsinogen in the presence of acid or, autocatalytically, in the presence of pepsin itself.Pepsin also has milk-clotting action similar to that of rennin and thereby facilitates the digestion of milk protein.t acts as a catalyst in the chemical breakdown of protein to form a mixture of polypeptides; it is formed from pepsinogen in the presence of acid or, autocatalytically, in the presence of pepsin itself.

Protease inhibitor (pharmacology) Protease inhibitors (PIs) are a class of antiviral drugs that are widely used to treat HIV/AIDS and hepatitis C. Protease inhibitors prevent viral replication selectively binding to viral proteases (e.g. HIV-1 protease) and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles.

Meaning & Symbolism of Protea Meaning & Symbolism of Protea. Among the oldest families of flowers on earth, dating back 300 million years, Greek legend tells us that protea were named after Proteus, the son of Poseidon. A sea god who had the power to know all things past, present and future, Proteus was defiant and preferred to nap on the island of Pharos rather than prophesize.

Enzyme Catalysis: The Serine Proteases Proteases Are Common and Widespread Enzymes. Proteases are enzymes that break the peptide bond that joins amino acids together in proteins. They are examples of hydrolases, enzymes that break a chemical bond by the addition of a water molecule.

Pepsin Enzyme Function Pepsin is an enzyme -- specifically, it's a proteolytic enzyme, meaning it helps digest proteins. Cells in the stomach secrete pepsin to help you digest the protein that you consume in food.Specialized cells in the intestine then absorb the digestion products of the protein into the bloodstream, and your cells take them up from there.ells in the stomach secrete pepsin to help you digest the protein that you consume in food.

How Does Protease Break Down Protein? Protease is an enzyme that breaks down proteins, specifically digestive proteins, according to Enzyme Essentials, an enzyme educational website. Protein is a vital part of your diet—an estimated 20 percent to 25 percent of your calories should come from it. Protein is a necessary building block for your muscles, skin, hormones and more.

Proteus From this feature of Proteus comes the adjective protean, with the general meaning of versatile, mutable, capable of assuming many forms.Protean has positive connotations of flexibility, versatility and adaptability.he children of Proteus, besides Eidothea, include Polygonus and Telegonus, who both challenged Heracles at the behest of Hera and were killed, one of Heracles' many successful encounters with representatives of the pre-Olympian world order. Another Proteus occurs in Greek myth as one of the fifty sons of King Aegyptus.

Protea Etymology [edit]. The genus Protea was named in 1735 by Carl Linnaeus after the Greek god Proteus, who could change his form at will, because they have such a wide variety of forms.he Proteaceae family to which proteas belong is an ancient one among angiosperms. Evidence from pollen fossils suggest Proteaceae ancestors grew in Gondwana, in the Upper Cretaceous, 75-80 million years ago.

- Proline (abbreviated as Pro or P) is an α- amino acid, one of the twenty main amino acids. Its codons are CCU, CCC, CCA, and CCG. It isn't essential, meaning the human body can make it. Uniquely among the 23 protein-forming amino acids, its amine nitrogen is bound to not one but two alkyl groups, thus making it a secondary amine (proline is sometimes called an imino acid).
