Ribulose 1,5-bisphosphate (RuBP) is an organic substance that is involved in photosynthesis, notably as the principal CO 2 acceptor in plants. [ 1 ] : 2 It is a colourless anion, a double phosphate ester of the ketopentose ( ketone -containing sugar with five carbon atoms) called ribulose .
For example, d-ribulose is an intermediate in the fungal pathway for d-arabitol production. Also, as the 1,5-bisphosphate, d-ribulose combines with carbon dioxide at the start of the photosynthesis process in green plants (carbon dioxide trap). [2] Ribulose has the same stereochemistry at carbons 3 and 4 as the five-carbon aldoses ribose and ...
Ribulose-5 phosphate can also be acted upon by phosphopentose epimerase to form xylulose 5-phosphate, which is used in the nonoxidative phase of the pentose phosphate pathway in humans to generate precursor molecules for the synthesis of aromatic amino acids and production of energy.

RuBisCO is important biologically because it catalyzes the primary chemical reaction by which inorganic carbon enters the biosphere.While many autotrophic bacteria and archaea fix carbon via the reductive acetyl CoA pathway, the 3-hydroxypropionate cycle, or the reverse Krebs cycle, these pathways are relatively small contributors to global carbon fixation compared to that catalyzed by RuBisCO.
