This chemical is often termed '''PGA''' when referring to the Calvin cycle. 3-phosphoglycerate is the resultant of the split of 6 carbon intermediate that is so unstable it splits instantly. And two 3-phosphoglycerate is produced for each molecule of CO<sub>2</sub>. ==Glycolysis== {{Biochemical Reaction |reaction_A_major_substrate=[[1,3-bisphosphoglycerate|1,3-bisphospho-<small>D</small>-glycerate]] |reaction_A_major_substrate_image=1,3-bisphospho-D-glycerate_wpmp.png |reaction_A_foward_enzyme=[[3-phosphoglycerate kinase]] |reaction_A_reverse_enzyme=[[3-phosphoglycerate kinase]] |reaction_A_reaction_direction_(foward/reversible/reverse)=reversible |reaction_A_minor_reverse_product(s)=[[ADP]] |reaction_A_minor_reverse_substrate(s)=[[adenosine triphosphate|ATP]] |reaction_A_minor_foward_substrate(s)=[[adenosine triphosphate|ADP]] |reaction_A_minor_foward_product(s)=[[Adenosine triphosphate|ATP]] |reaction_A_major_product=[[3-phosphoglycerate|3-phospho-<small>D</small>-glycerate]] |reaction_A_major_product_image=3-phospho-D-glycerate_wpmp.png |reaction_B_foward_enzyme=[[Phosphoglyceromutase]] |reaction_B_reverse_enzyme=[[Phosphoglyceromutase]] |reaction_B_reaction_direction_(foward/reversible/reverse)=reversible |reaction_B_minor_foward_substrate(s)= |reaction_B_minor_foward_product(s)= |reaction_B_minor_reverse_product(s)= |reaction_B_minor_reverse_substrate(s)= |reaction_B_major_product=[[2-phosphoglycerate|2-phospho-<small>D</small>-glycerate]] |reaction_B_major_product_image=2-phospho-D-glycerate_wpmp.png }} {{KEGG compound|C00236}} {{KEGG enzyme|2.7.2.3}} {{KEGG compound|C00197}} {{KEGG enzyme|5.4.2.1}} {{KEGG compound|C00631}} ==Calvin cycle== In the Calvin cycle, two glycerate 3-phosphate molecules are reduced to form two molecules of [[glyceraldehyde 3-phosphate]] (PGAL). This is the first compound formed during the C3 or Calvin cycle. It is a reactive biomolecule which is easily reduced. ==Amino acid synthesis== Glycerate 3-phosphate is also a precursor for [[serine]], which in turn, can create [[cysteine]] and [[glycine]] through the [[homocysteine]] cycle. ==See also== {{Glycolysis}} {{metabolism-stub}} [[Category:Carboxylate anions]] [[Category:Organophosphates]] [[Category:Photosynthesis]] [[it:3-fosfoglicerato]] [[ja:3-ホスホグリセリン酸]] [[pl:3-Fosfoglicerynian]] [[zh:3-磷酸甘油酸]]
