Answer:
It means that the cyanogen bromide hydrolyzes methionine residues with high efficiency, while trypsin is an enzyme that cuts proteins at lysine and arginine peptidic bonds, thereby producing 4 and 15 polypeptides, respectively.
Explanation:
Cyanogen bromide is a pseudohalogen compound that is used to cut the C-terminus of the methionine residues. On the other hand, the trypsin is an enzyme produced by the pancreas as trypsinogen that is used by the digestive system (intestine) to digest polypeptides.
Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
