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-. The conjugate base of α-aminobutyric acid is the carboxylate α-aminobutyrate.
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.
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 .
Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
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 ...
Aminobutyric acid or aminobutanoic acid may refer to any of three isomeric chemical compounds: α-Aminobutyric acid (AABA) β-Aminobutyric acid (BABA)
The C-B bond has low polarity (electronegativity 2.55 for carbon and 2.04 for boron).Alkyl boron compounds are in general stable, though easily oxidized. Boron often forms electron-deficient compounds without a full octet, such as the triorganoboranes.
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 ...
