Bookmark or Share- Amino Acids - Benefits, Structure & Function | Biology DictionaryDefinition. Amino acids are the building blocks of polypeptides and proteins and play important roles in metabolic pathway, gene expression, and cell signal transduction regulation. A single organic amino acid molecule contains two functional groups – amine and carboxyl – and a unique side chain.
- 20 Amino Acids - Science Notes and ProjectsAmino acids are organic compounds containing an amino group (-NH 2) and a carboxyl group (-COOH). This is the general structure of an amino acid: where R is the side chain functional group that distinguishes one amino acid from another. This is a table of the 20 amino acids derived from proteins.
- Amino acid | Definition, Structure, & Facts | BritannicaAmino 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 acid - WikipediaAmino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] . Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2] . Only these 22 appear in the genetic code of life. [3] [4]
- Introduction to proteins and amino acids - Khan AcademyThere are 20 types of amino acids commonly found in proteins. Image credit: OpenStax Biology. Amino acids share a basic structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group ( NH 2 ), a carboxyl group ( COOH ), and a hydrogen atom.
