ri·bu·lose

(rī'byū-lōs),
The 2-keto isomer of ribose. As the 5-phosphate, it participates in the pentose monophosphate shunt; as the 1,5-bisphosphate, it combines with CO2 at the start of the photosynthetic process in green plants ("carbon dioxide trap"); d-ribulose is the epimer of d-xylulose.

ribulose

a pentose sugar, found in syrup, which is important in carbohydrate metabolism. Formula: C5H10O5
