Art and Science: An Eternal Relationship
How is science involved with art? Neither seems to have much directly in common. But one of art’s...
Trypsin is a serine protease found in the digestive system of many vertebrates where it hydrolyzes proteins. Through trypsinisation, it cleaves peptides at the carboxyl side of arginine and lysine, unless they are followed by a proline.
Trypsin has an optimal operating pH of about 7.5-8.5 and optimal operating temperature of about 37°C. Unlike chymotrypsin, the activity of trypsin is not affected by the inhibitor tosyl phenylalanyl chloromethyl ketone (TPCK).
Trypsin 1:250 indicates that one part trypsin will digest 250 parts casein in the USP activity assay.
