gamma-Aminobutyric acid, or γ-aminobutyric acid / ˈ ɡ æ m ə ə ˈ m iː n oʊ b juː ˈ t ɪr ɪ k ˈ æ s ɪ d /, or GABA / ˈ ɡ æ b ə /, is the chief inhibitory neurotransmitter in the developmentally mature mammalian central nervous system. Its principal role is reducing neuronal excitability throughout the nervous system.
Optical isomerism is a form of stereoisomerism. This page explains what stereoisomers are and how you recognise the possibility of optical isomers in a molecule. What is stereoisomerism? What are isomers? Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space.
The purpose of the present invention is to provide a highly versatile production method with which it is possible to use any hydrophobic peptide as the object of purification regardless of the type of amino acid residue at the N-terminal and to flexibly select a hydrophilic unit in accordance with the type of hydrophobic peptide when conducting HPLC purification by hydrophilizing a solid-phase .

The amino acid sequence of a protein is determined by the information found in the cellular genetic code. The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acids. These gene codes not only determine the order of amino acids in a protein, .
The present invention relates to novel compounds that are analogs of glutamic acid and gamma-aminobutyric acid (GABA). More specifically, the analogs are useful as antiseizure therapy for central nervous system disorders such as epilepsy, Huntington's chorea, cerebral ischemia, Parkinson's disease, tardive dyskinesia, and spasticity.

Carboxylic acid, any of a class of organic compounds in which a carbon atom is bonded to an oxygen atom by a double bond and to a hydroxyl group by a single bond. They are generally more acidic than other organic compounds containing hydroxyl groups but are generally weaker than mineral acids such as hydrochloric acid.
NH 2 CH 2 CH 2 CH 2 COOH, an acid formed by the decarboxylation of glutaminic acid under the action of the enzyme decarboxylase. In the body, metabolism of gamma-aminobutyric acid gives succinic acid, which participates in the tricarboxylic acid cycle. Free gamma-aminobutyric acid is found in many plants.

DA has the chemical formula (C 6 H 3 . the GABA transaminase enzyme catalyzes the conversion of 2-oxoglutarate and 4-aminobutanoic acid into glutamate and succinic semialdehyde.
Lactone is derived from a compound called Lactide,that is generated by the dehydration of lactic acid.It has a ring of 2 or more carbon atoms and 1 oxygen atom.Explore more Byju's.
The isoelectric point of an amino acid is the pH at which the amino acid has a neutral charge. You will learn how to calculate the isoelectric point, and the effects of pH on the amino acid's overall charge. We will also discuss zwitterions, or the forms of amino acids that dominate at the isoelectric point…
