1,3-Bisphosphoglyceric acid (1,3-Bisphosphoglycerate or 1,3BPG) is a 3-carbon organic molecule present in most, if not all, living organisms.It primarily exists as a metabolic intermediate in both glycolysis during respiration and the Calvin cycle during photosynthesis. 1,3BPG is a transitional stage between glycerate 3-phosphate and glyceraldehyde 3-phosphate during the fixation/reduction of ...

A typical oxidant is nitric acid, but catalytic oxidations have been developed also: [2] [3] HOCH 2 CH(OH)CH 2 OH + O 2 → HOCH 2 CH(OH)CO 2 H + H 2 O. As glycerol is prochiral, the oxidation of the two terminal alcohol groups gives distinct enantiomers of glyceric acid. Oxidation of both primary alcohols gives tartronic acid:

2,3-BPG is formed from 1,3-BPG by the enzyme BPG mutase.It can then be broken down by 2,3-BPG phosphatase to form 3-phosphoglycerate.Its synthesis and breakdown are, therefore, a way around a step of glycolysis, with the net expense of one ATP per molecule of 2,3-BPG generated as the high-energy carboxylic acid-phosphate mixed anhydride bond is cleaved by 2,3-BPG phosphatase.
The above photo shows the positive results of the number 2 Marquis reagent presumptive drug test when used with a sample of opium. It is the primary presumptive test used in Ecstasy reagent testing kits. It can also be used to test for such substances as opiates (e.g. codeine, heroin), and phenethylamines (e.g. 2C-B, mescaline).
An acid anhydride is a compound that has two acyl groups bonded to the same oxygen atom. [1] A common type of organic acid anhydride is a carboxylic anhydride, where the parent acid is a carboxylic acid, the formula of the anhydride being (RC(O)) 2 O. Symmetrical acid anhydrides of this type are named by replacing the word acid in the name of ...
