α-Aminobutyric acid (AABA), also known as homoalanine in biochemistry, is a non-proteinogenic alpha amino acid with chemical formula C 4 H 9 NO 2. The straight two carbon side chain is one carbon longer than alanine, hence the prefix homo-. Homoalanine is biosynthesised by transaminating oxobutyrate, a metabolite in isoleucine biosynthesis.
β-Aminobutyric acid (BABA) is an isomer of the amino acid aminobutyric acid with the chemical formula C 4 H 9 NO 2.It has two isomers, α-aminobutyric acid and γ-aminobutyric acid (GABA), a neurotransmitter in animals that is also found in plants, where it may play a role in signalling.
Since late 2000s, propanephosphonic acid anhydride, sold commercially under various names such as "T3P", has become a useful reagent for amide bond formation in commercial applications. It converts the oxygen of the carboxylic acid into a leaving group, whose peptide-coupling byproducts are water-soluble and can be easily washed away.
Isovaleric acid, also known as 3-methylbutanoic acid or β-methylbutyric acid, is a branched-chain alkyl carboxylic acid with the chemical formula (CH 3) 2 CHCH 2 CO 2 H. It is classified as a short-chain fatty acid. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. The compound occurs naturally and can be found in ...
The biuret reagent is made of sodium hydroxide (NaOH) and hydrated copper(II) sulfate, together with potassium sodium tartrate, [7] the latter of which is added to chelate and thus stabilize the cupric ions. The reaction of the cupric ions with the nitrogen atoms involved in peptide bonds leads to the displacement of the peptide hydrogen atoms ...
Homocystine is the organosulfur compound with the formula (HO 2 CCH(NH 2)CH 2 CH 2 S) 2. It is disulfide derived from oxidation of homocysteine . [ 2 ] Its relationship with homocysteine is analogous to the relationship between cystine and cysteine .
Carboxylation is a chemical reaction in which a carboxylic acid is produced by treating a substrate with carbon dioxide. [1] The opposite reaction is decarboxylation.In chemistry, the term carbonation is sometimes used synonymously with carboxylation, especially when applied to the reaction of carbanionic reagents with CO 2.
2-Aminoisobutyric acid (also known as α-aminoisobutyric acid, AIB, α-methylalanine, or 2-methylalanine) is the non-proteinogenic amino acid with the structural formula H 2 N-C(CH 3) 2-COOH. It is rare in nature, having been only found in meteorites, [ 2 ] and some antibiotics of fungal origin, such as alamethicin and some lantibiotics .
