Explanation Reason for correct option: Option (a) is S-Adenosylmethionine. It is the most common methyl donor substrate, which is also involved in transsulfuration and aminopropylation reactions...

The common methyl donor in the cell should be determined. Concept introduction: Amino acid synthesis is the biochemical process by which amino acids are synthesized. Organisms are not able to synthesize all amino acids. Humans can synthesize only 11 amino acids out of the 20 amino acids. These amino acids are termed as the non-essential amino acids, and the remaining amino acids are termed as the essential amino acids.
