Metabolite Identification
Common NameD-erythrulose 4-phosphate
DescriptionD-erythrulose 4-phosphate is a carbohydrate metabolite belonging to the class of phosphorylated sugars. Its chemical structure features a four-carbon backbone with a phosphate group attached to the fourth carbon, making it a crucial intermediate in various metabolic pathways. D-erythrulose 4-phosphate is synthesized from glycolaldehyde through a series of enzymatic reactions involving transketolase and kinase, leading to its eventual conversion to D-erythrose 4-phosphate (PMID:3987693 ). The enzyme responsible for the interconversion of D-erythrose 4-phosphate and D-erythrulose 4-phosphate has been isolated from beef liver, highlighting its significance in metabolic processes (PMID:3987693 ). Analytical techniques such as gas chromatography/mass spectrometry have demonstrated that D-erythrulose 4-phosphate constitutes approximately 90% of the total tetrose 4-phosphate present after equilibration, indicating its predominance in the equilibrium state (PMID:6547672 ). Furthermore, this compound can also be formed from D-threose 4-phosphate, showcasing its role in the dynamic interconversion of tetrose phosphates (PMID:6547672 ). Overall, D-erythrulose 4-phosphate plays a pivotal role in carbohydrate metabolism and serves as an important precursor in various biosynthetic pathways.
