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 ...

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 molecular formula C 3 H 8 O 10 P 2 (molar mass: 266.035 g/mol) may refer to: 1,3-Bisphosphoglyceric acid (1,3-BPG) 2,3-Bisphosphoglyceric acid (2,3-BPG)
One of the molecules is 2,3-bisphosphoglycerate (2,3-BPG) and it enhances hemoglobin's ability to release oxygen. [13] 2,3-BPG interacts much more with hemoglobin A than hemoglobin F. This is because the adult β subunit has more positive charges than the fetal γ subunit, which attract the negative charges from 2,3-BPG.
His 11: the nucleophile of the 1,2-BPG to 1,3-BPG reaction. Rotates back and forth with the help of His-188 to get in an in-line position in order to attack the 1’ phosphate group. [3] His-188: involved in overall stability of protein, [4] as well as hydrogen bonding to substrate, as His-11, which it pulls into its catalytic position.
