Transmethylation, decarboxylation and interconversion of amino acids

Transmethylation is a biochemical process that involves the transfer of a methyl group (CH3) from one molecule to another. Methyl groups consist of one carbon atom bonded to three hydrogen atoms, and they can be transferred between different molecules in a variety of biological reactions.

 

Transmethylation reactions are important for numerous physiological processes in the body. They play a crucial role in the metabolism of various substances, including nucleic acids, proteins, neurotransmitters, hormones, and lipids. These reactions are catalyzed by specific enzymes called methyltransferases.

Decarboxylation is a chemical reaction in which a carboxyl group (-COOH) is removed from a molecule as carbon dioxide (CO2). It is the process of removing a carboxyl group from an organic compound, resulting in the formation of a new compound with one less carbon atom.

 

Carboxyl groups are functional groups consisting of a carbon atom bonded to both an oxygen atom and a hydroxyl group (-OH). They are commonly found in organic acids such as carboxylic acids. During decarboxylation, the carboxyl group undergoes a chemical reaction, leading to the release of carbon dioxide.

Amino acids can undergo interconversion through various biochemical reactions. These interconversions are important for maintaining amino acid balance in the body and facilitating the synthesis of different proteins.
