Proteolytic
Proteolytic
Proteolytic (pronunciation: pro·teo·lyt·ic /ˌprōtēəˈlidik/) is a term used in biochemistry to describe the process of protein catabolism by hydrolysis of peptide bonds. The term is derived from the Greek words "proteios" meaning "primary" and "lysis" meaning "loosening".
Etymology
The term "proteolytic" is derived from two Greek words. "Proteios" (πρωτεῖος), meaning "primary" or "in the lead", and "lysis" (λύσις), meaning "loosening" or "dissolving". The term is used to describe the process where proteins are broken down into smaller polypeptides or single amino acids by enzymes called proteases.
Process
Proteolytic process involves the breakdown of proteins into smaller polypeptides or amino acids. This is achieved by the enzymatic action of proteases. Proteases are enzymes that perform proteolysis, they are also known as proteolytic enzymes or proteinases.
