Side chain
Side Chain
A Side Chain (pronounced: /ˈsaɪd tʃeɪn/) is a chain of atoms attached to a core part of a molecule. In the context of biochemistry, the side chain is a component of an amino acid that differentiates it from other amino acids.
Etymology
The term "Side Chain" is derived from its structural position. It is a chain of atoms that is attached to the main chain or backbone of a molecule, hence the name "Side Chain".
Biochemistry
In Biochemistry, a side chain is part of an Amino Acid that differentiates it from other amino acids. The side chain is attached to the alpha carbon atom of the amino acid. The properties of the side chain influence the characteristics of the amino acid, and therefore the role it plays in proteins.
Chemistry
In Chemistry, a side chain is a group of atoms attached to a core part of a molecule. The side chain can influence the properties of the molecule, including its reactivity, polarity, and the types of reactions it can undergo.
Related Terms
- Amino Acid: Amino acids are organic compounds composed of amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid.
- Protein: Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. The properties of a protein are determined by its constituent amino acids, and therefore by the nature of its side chains.
- R Group: The term "R group" is used in biochemistry to refer to the side chain of an amino acid.
