Simply so, is protease and pepsin the same thing?

Pepsin is a type of protease which serves as the main digestive enzyme in the stomach. On the other hand, proteases are the protein digestive enzymes which break down proteins into small peptides and amino acids.

Also, what is the difference between protease and proteinase? Proteases (also called peptidases) are enzymes that degrade proteins by hydrolysis of peptide bonds. Endopeptidases break bonds of nonterminal amino acids (within the protein) while exopeptidases break bonds of terminal amino acids (the end of the protein). Proteinase is synonymous with endopeptidase.

Simply so, what type of protease is pepsin?

Pepsin is an aspartic protease, using a catalytic aspartate in its active site. It is one of three principal proteases in the human digestive system, the other two being chymotrypsin and trypsin.

Does Pepsin work in a basic environment?

pH and Enzyme Function. For example, the enzyme pepsin, which works in your stomach, functions best in a strongly acidic environment. Lipase, an enzyme found in your small intestine, works best in a basic environment. When the pH changes, the active site progressively distorts and affects enzyme function.
