Xylulose is a ketopentose, a monosaccharide containing five carbon atoms, and including a ketone functional group. It has the chemical formula C₅H₁₀O₅. In nature, it occurs in both the L- and D-enantiomers.[3] 1-Deoxyxylulose is a precursor to terpenes via the nonmevalonic acid pathway.[4]

Pathology

L-Xylulose accumulates in the urine in patients with pentosuria, due to a deficiency in L-xylulose reductase. Since L-xylulose is a reducing sugar like D-glucose, pentosuria patients have been wrongly diagnosed in the past to be diabetic.

gollark: Those are not, as far as I know, actually that competitive.

gollark: There's just a lot of waste on stuff like advertising and reinventing things done by competitors which is at least theoretically avoidable.

gollark: No, we have perfectly functional competitive markets for things like food and TVs and furniture and whatever.

gollark: Central planning instead of our competitive systems could be way more efficient, except the incentives don't really work and nobody can be trusted to do it.

gollark: It's possible that I don't really like informal social/status-game-y methods of distributing things because I'm not very good at them and find them unpleasant. But I still don't really like them.
