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.
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 ...
In chemistry, autoprotolysis is a molecular autoionization, a chemical reaction in which a proton is transferred between two identical molecules, one of which acts as a Brønsted acid, releasing a proton that is accepted by the other molecule, which acts as a Brønsted base. [1]
The reaction is much less efficient in homogeneous systems such as dichloromethane, toluene and acetonitrile or even the solvent free reaction or even the water reaction but now at 50°C. The on water effect is also studied in cycloadditions of the type: [6] In this reaction the alkyne methyl 2-octynoate reacts with triphenylphosphine to an ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
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 .
Aminomethyl propanol (AMP) is an organic compound with the formula H 2 NC(CH 3) 2 CH 2 OH. It is colorless liquid that is classified as an alkanolamine. It is a useful buffer and a precursor to numerous other organic compounds. [2] Aminomethyl propanol is typically sold as a solution of the material in water, for which different concentrations ...
