WebA hydroxyl (alcohol group) is an –OH group covalently bonded to a carbon atom. The oxygen atom is much more electronegative than either the hydrogen or the carbon, … WebChemistry of Crosslinking. Crosslinking is the process of chemically joining two or more molecules by a covalent bond. The technique, often called bioconjugation when referring to its use with proteins and other biomolecules, is an essential component of many proteomics methods, including creation of detectable probes for western blotting and ...

Protecting Groups in Peptide Synthesis - Springer Nature

WebPeptide synthesis. Coupling of two amino acids in solution. The unprotected amine of one reacts with the unprotected carboxylic acid group of the other to form a peptide bond. In this example, the second reactive group (amine/acid) in each of the starting materials bears a protecting group. In organic chemistry, peptide synthesis is the ... Webanswer choices.

WebQuestion. The two steps that the question is asking is adding a methyl group and hydroxyl group to cytosine. I was able to eliminate B and C since a hydrolase made no sense. However, when adding a hydroxyl group, since we are adding a substituent, I thought that it would be a ligase reaction since it's presumably making a new C-O bond.
