[Definition]

ChEBI: The D-enantiomer of psicose.
[Enzyme inhibitor]

This ketohexose (FW = 180.16 g/mol), also known as D-ribo-2-hexulose and reportedly fpound in cane molasses, has epimers of D-psicose are Dfructose, D-sorbose, and L-tagatose. D-Psicose is an alternative substrate for fructokinase. The structural composition of D-psicose at 27°C in D2O is 22% a-pyranose, 24% b-pyranose, 39% a-furanose, and 15% bfuranose. Target(s): ketohexokinase, or hepatic fructokinase; also alternative substrate.
