Metabolite Identification
Common NameD-Psicose
DescriptionD-Psicose is a rare sugar belonging to the class of monosaccharides, specifically a C-3 epimer of D-fructose. Its chemical structure features a six-carbon backbone with a hydroxyl group at the third carbon, distinguishing it from its isomeric counterparts. D-Psicose is synthesized through the enzymatic action of D-psicose 3-epimerase (DPEase), which catalyzes the conversion of D-fructose into D-psicose. This enzymatic pathway is critical for its production, as demonstrated by studies showing that purified DPEase achieves a maximum conversion rate of 17.03% under optimal conditions (PMID:40598404 ). The enzyme can be immobilized and reused, maintaining 83.38% relative activity over five cycles, which enhances its industrial viability (PMID:40598404 ). The stability and efficiency of DPEase make it a promising candidate for large-scale D-psicose production, potentially reducing energy costs and simplifying synthesis processes (PMID:40598404 ). D-Psicose's low-calorie nature and health benefits position it as a valuable sweetener in the food and pharmaceutical industries, further emphasizing the importance of understanding its chemical properties and production pathways (PMID:40598404 ).
