Egg White Cystatin-A Review

Abstract

Hen eggs are widely used, not only for human consumption, but also as an important material in food production and in pharmaceutical and cosmetics industry. Cystatin is a biologically active component of egg white, mostly used as an inhibitor of papain-like cysteine proteases. It was isolated from chicken egg white and has later been used in the nomenclature of structurally and functionally related proteins. Cystatins from animals, including mouse, rat, dog, cow and chicken egg white have been isolated and recently used in foodstuffs and drug administration. Cystatin has found its place and use in medicine due to its antimicrobial, antiviral and insecticidal effects, for the prevention of cerebral hemorrhage and control of cancer cell metastasis.

Belance jajeta je u širokoj upotrebi i to ne samo za ishranu ljudi već i kao sirovina za prehrambenu industriju, farmaceutsku i kozmetičarsku industriju. Cistatin je biološki aktivna komponenta belanca jaja i većinom se koristi kao inhibitor cistein proteaza nalik na papain. Cistatin je izolovan iz kokošjih jaja i kasnije upotrebljen za formiranje nomenklature strukturno i funkcionalno sličnih proteina. Cistatini poreklom od životinja, uključujući i miševe, pacove, pse, goveda i iz belanaca kokošjih jaja, izolovani su i nedavno su upotrebljeni za ishranu ljudi i za farmaceutsku industriju. Cistatin na našao svoju upotrebu i upotrebu u medicini zahvaljujući antibakterijskim, antivirusnim i insekticidnim efektima i to u cilju prevencije cerebralnih hemoragija i za kontrolu metastaza kod tumora.
