Proteolysis

proteolysis

(Science: cell biology) cleavage of proteins by proteases. Limited proteolysis occurs where proteins are functionally modified (activated in the case of zymogens) by highly specific proteases.

Re: Proteolysis of protease

That does make sense. Would you happen to know whether pancreatic lipase fits into the specificity of pancreatic protease? I have another question though. Our teacher told us that triglycerides (found in ordinary milk) are hydrolyzed into monoacylglycerid [or monoacylglycerol maybe?] + 2 fatty acids...

Re: Proteolysis of protease

Not quite all the answer. Understand that proteases refers to a large group of enzymes - each of which has a specificity - based on amino acid sequence, charge, size, etc. For example trypsin cleaves peptide chains at the carboxyl side of the amino acids lysine and arginine, except when either is fo...

Proteolysis of protease

... at different temperatures. Pancreatin also contains the enzymes protease and amylase. I read more about protease and found out that it conducts proteolysis, which is the break down of peptide bonds between amino acids. However, I know that lipase is a globular protein and thus basically a chain ...

Casein

I always thought caesin was just a common protein in milk. If you process it by partial proteolysis (with pancreatic extracts or whatever), you have a mixture of small peptides and amino acids you add to culure media as a source of amino acids. Unprocessed caesin is ...
