- Difference between Peptone, Peptide and Proteose
Long, Confusing and Out-Dated Details The terms peptone and proteose were first used in the late 19th century, which makes finding substantive definitions, well, difficult
- Proteases in the blood - Biology Stack Exchange
Also the proteases may have certain specificities but not others Certain proteins may not contain the moieties that the enzymes need to bind and catalyze the reactions and this acts to "protect" the protein from degradation
- proteins - Why are prions in animal diets not destroyed by the . . .
Proteases have clefts, or subpockets, into which proteins fit, where the substrate (protein) gets cut Infectious or pathogenic prions are resistant to proteases , because of their three-dimensional shape, which hides away parts of the prion that would normally fit in proteases and which would cause the prion to be digested
- molecular biology - Does sample buffer require EDTA for protein . . .
Both steps ensure that proteases are either inhibited or completely denaturated, which will both protect the sample The only reason I can think of for using EDTA is that it can help to destabilize your target protein, when a co-factor which is important for the structure is complexed by EDTA and thus keep it in solution after the denaturation
- biochemistry - Whats the role of bromelain in pineapple? - Biology . . .
Bromelain refers to one of two proteases found in pineapple and its relatives Like other proteases, many believe it has therapeutic uses and it's the subject of a lot of research But what role does it play in the pineapple itself? Why does pineapple (or papaya, for that matter) generate large quantities of protease when other plants do not?
- What happens to the enzymes produced by the digestive system?
$\begingroup$ Proteases, being themselves proteins, are cleaved by other protease molecules, sometimes of the same variety $\endgroup$ – JM97 Commented Mar 11, 2017 at 16:24
- biochemistry - What is the process of degradation of proteins into . . .
$\begingroup$ In addition to proteasome and lysosome, soluble (non-organelle) proteases may become important, depending on circumstances $\endgroup$ – nvja Commented Mar 28, 2016 at 4:11
- Why is pepsin able to operate at low pH? - Biology Stack Exchange
Pepsin is a protease that operates in the acid pH of the stomach Many proteins are denatured at low pH, and most enzymes — whether or not they denature — require a higher pH for activity
