Amino acid metabolism

Amino Acid Metabolism

Amino acid metabolism refers to the set of biochemical processes in the body that maintain the nitrogen balance and synthesize and break down amino acids.

Pronunciation

Amino acid metabolism: /əˈmiːnoʊ ˈæsɪd mɪˈtæbəlɪzəm/

Etymology

The term "amino acid metabolism" is derived from the words "amino acid", which refers to organic compounds composed of amino groups (-NH2) and carboxyl groups (-COOH), and "metabolism", which refers to the chemical reactions in organisms necessary for life.

Overview

Amino acid metabolism involves three key processes: transamination, deamination, and decarboxylation. These processes are crucial for the synthesis and breakdown of amino acids, as well as the production of energy.

Transamination

Transamination is the process by which an amino group from one amino acid is transferred to a ketone or aldehyde to form a new amino acid. This is a key process in the synthesis of non-essential amino acids.

Deamination

Deamination is the removal of an amino group from an amino acid. The resulting products, ammonia and a keto acid, can be used in other metabolic processes.

Decarboxylation

Decarboxylation is the removal of a carboxyl group from an amino acid, resulting in the formation of an amine and carbon dioxide. This process is important in the synthesis of neurotransmitters and other biologically active amines.
