N-Benzylmercapto-carbonyl-N'-phenyl-thioharnstoff, also known as BPTI (Bovine Pancreatic Trypsin Inhibitor), is a naturally occurring protein that serves as a potent inhibitor of trypsin, a digestive enzyme that breaks down proteins into smaller peptides. It is composed of 58 amino acids and has a molecular weight of approximately 6512.55 g/mol. BPTI plays a crucial role in regulating the activity of trypsin in the pancreas, preventing excessive proteolysis and maintaining the balance of protein digestion. The chemical structure of BPTI features a benzylmercapto-carbonyl group attached to a phenyl-thioharnstoff moiety, which is responsible for its inhibitory activity. This protein has been extensively studied for its potential therapeutic applications, including the treatment of various inflammatory and autoimmune diseases, as well as its use as a research tool in understanding the mechanisms of protein-protein interactions.
The CAS Registry Mumber 5729-37-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 9 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5729-37: (6*5)+(5*7)+(4*2)+(3*9)+(2*3)+(1*7)=113 113 % 10 = 3 So 5729-37-3 is a valid CAS Registry Number.
