The normal glycolytic pathway generates 1,3-BPG, which may be dephosphorylated by phosphoglycerate kinase (PGK), generating ATP, or it may be shunted into the Luebering-Rapoport pathway, where bisphosphoglycerate mutase catalyzes the transfer of a phosphoryl group from C1 to C2 of 1,3-BPG, giving 2,3-BPG. 2,3-BPG, the most concentrated organophosphate in the erythrocyte, forms 3-PG by the ...
In biochemistry, the Luebering–Rapoport pathway (also called the Luebering–Rapoport shunt) is a metabolic pathway in mature erythrocytes involving the formation of 2,3-bisphosphoglycerate (2,3-BPG), which regulates oxygen release from hemoglobin and delivery to tissues. 2,3-BPG, the reaction product of the Luebering–Rapoport pathway was first described and isolated in 1925 by the ...
2,3-Bisphosphoglycerate 3-phosphatase (EC 3.1.3.80, MIPP1, 2,3-BPG 3-phosphatase) is an enzyme with systematic name 2,3-bisphospho-D-glycerate 3-phosphohydrolase. [1] This enzyme catalyses the following reaction:
Because the main function of bisphosphoglycerate mutase is the synthesis of 2,3-BPG, this enzyme is found only in erythrocytes and placental cells. [2] In glycolysis, converting 1,3-BPG to 2,3-BPG would be very inefficient, as it just adds another unnecessary step. Since the main role of 2,3-BPG is to shift the equilibrium of hemoglobin toward ...
The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt or HMP shunt) is a metabolic pathway parallel to glycolysis. [1] It generates NADPH and pentoses (five- carbon sugars ) as well as ribose 5-phosphate , a precursor for the synthesis of nucleotides . [ 1 ]

Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
"9 to 5" singer Dolly Parton opened up on Bunnie Xo's 'Dumb Blonde' podcast about why her husband Carl Dean doesn't like to attend any events with her.
