α-Aminobutyric acid is one of the three isomers of aminobutyric acid. The two other are the neurotransmitter γ-Aminobutyric acid (GABA) and β-Aminobutyric acid (BABA) which is known for inducing plant disease resistance. The conjugate base of α-aminobutyric acid is the carboxylate α-aminobutyrate. This amino acid has been detected in ...
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.
The values below are standard apparent reduction potentials (E°') for electro-biochemical half-reactions measured at 25 °C, 1 atmosphere and a pH of 7 in aqueous solution. [1] [2] The actual physiological potential depends on the ratio of the reduced (Red) and oxidized (Ox) forms according to the Nernst equation and the thermal voltage.
One equivalent of PCl 3 can react with three equivalents of acid, producing one equivalent of H 3 PO 3, or phosphorus acid, in addition to the desired acid chloride. PCl 5 reacts with carboxylic acids in a 1:1 ratio, and produces phosphorus(V) oxychloride (POCl 3 ) and hydrogen chloride (HCl) as byproducts.
pK a H 2 CO 3 is the negative logarithm (base 10) of the acid dissociation constant of carbonic acid. It is equal to 6.1. [HCO − 3] is the concentration of bicarbonate in the blood [H 2 CO 3] is the concentration of carbonic acid in the blood; When describing arterial blood gas, the Henderson–Hasselbalch equation is usually quoted in terms ...
In organic chemistry, ammoxidation is a process for the production of nitriles (R−C≡N) using ammonia (NH 3) and oxygen (O 2). It is sometimes called the SOHIO process, acknowledging that ammoxidation was developed at Standard Oil of Ohio. [1] [2] The usual substrates are alkenes.

The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] (BOC group) is an acid-labile protecting group used in organic synthesis. The BOC group can be added to amines under aqueous conditions using di- tert -butyl dicarbonate in the presence of a base such as sodium hydroxide :
