Abstract

Formation of racemic pentose-2,4-bisphosphates is demonstrated, starting from glycolaldehyde phosphate and glyceraldehyde-2-phosphate, and induced by mixed valence double layer metal hydroxide minerals. The reactions proceed from dil. aq. reactant solns. (1.5 mM) at near neutral pH. Conditions have been established, where ribose-2,4-bisphosphate is the major product (.apprx. 48%) among the pentose-2,4-bisphosphates, which are formed with up to 25% yield. [on SciFinder (R)]

Glyceraldehyde 3-phosphate

Glyceraldehyde 3-phosphate, also known as triose phosphate or 3-phosphoglyceraldehyde and abbreviated as G3P, GA3P, GADP, GAP, TP, GALP or PGAL, is a metabolite that occurs as an intermediate in several central pathways of all organisms. With the chemical formula H(O)CCH(OH)CH2OPO32-, this anion is a monophosphate ester of glyceraldehyde. D-glyceraldehyde 3-phosphate is formed from the following three compounds in reversible reactions: Fructose-1,6-bisphosphate (F1,6BP), catalyzed by aldolase.

Pentose

In chemistry, a pentose is a monosaccharide (simple sugar) with five carbon atoms. The chemical formula of many pentoses is C5H10O5, and their molecular weight is 150.13 g/mol. Pentoses are very important in biochemistry. Ribose is a constituent of RNA, and the related molecule, deoxyribose, is a constituent of DNA. Phosphorylated pentoses are important products of the pentose phosphate pathway, most importantly ribose 5-phosphate (R5P), which is used in the synthesis of nucleotides and nucleic acids, and erythrose 4-phosphate (E4P), which is used in the synthesis of aromatic amino acids.

Ribose

Ribose is a simple sugar and carbohydrate with molecular formula C5H10O5 and the linear-form composition H−(C=O)−(CHOH)4−H. The naturally-occurring form, -ribose, is a component of the ribonucleotides from which RNA is built, and so this compound is necessary for coding, decoding, regulation and expression of genes. It has a structural analog, deoxyribose, which is a similarly essential component of DNA. -ribose is an unnatural sugar that was first prepared by Emil Fischer and Oscar Piloty in 1891.
