1. Amino Acid: Benefits & Food Sources - Cleveland Clinic
Amino acids are involved in many important roles in your body, including breaking down food, building muscle and boosting your immune system.
Amino acids are the building blocks of protein. Your body needs 20 amino acids to function correctly. Nine of these amino acids are called essential amino acids.

4. Amino acid | Definition, Structure, & Facts | Britannica
Sep 9, 2024 · An amino acid is an organic molecule that is made up of a basic amino group (−NH 2 ), an acidic carboxyl group (−COOH), and an organic R group (or side chain)
Amino acid, any of a group of organic molecules that consist of a basic amino group, an acidic carboxyl group, and a unique organic side chain. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Examples of amino acids include glycine and threonine.

Amino acids are required for the synthesis of body protein and other important nitrogen-containing compounds, such as creatine, peptide hormones, and some ...
Both animal and plant proteins are made up of about 20 common amino acids. The proportion of these amino acids varies as a characteristic of a given protein, but all food proteins—with the exception of gelatin—contain some of each. Amino nitrogen accounts for approximately 16% of the weight of proteins. Amino acids are required for the synthesis of body protein and other important nitrogen-containing compounds, such as creatine, peptide hormones, and some neurotransmitters. Although allowances are expressed as protein, a aIn this chapter, protein is equated with nitrogen × 6.25, i.e., crude protein containing 16% nitrogen. Specific food proteins have greater (cereals) or lesser (milk) percentages of nitrogen. See USDA Agricultural Handbook Series 8 (1976–1989) for factors used in food composition tables.the biological requirement is for amino acids.

Proteins are made up of 20 amino acids. Each amino acid has an α-carboxyl group, a primary α-amino group, and a side chain called the R group (see Image. Amino Acid Generic Structure). Unlike other amino acids, proline has a secondary amino group. The side chain varies from one amino acid to the other. Nutritionally, amino acids are divided into 3 groups—essential, nonessential, and semi-essential. Semi-essential amino acids are synthesized by the body but are designated essential during periods of stress.
