Ribose vs. Ribulose

Ribosenoun

(carbohydrate) A naturally occurring pentose sugar, which is a component of the nucleosides and nucleotides that constitute the nucleic acid biopolymer, RNA. It is also found in riboflavin.

Ribosenoun

a pentose sugar important as a component of ribonucleic acid

Ribose

Ribose is a simple sugar and carbohydrate with molecular formula C5H10O5 and the linear-form composition H−(C=O)−(CHOH)4−H. The naturally-occurring form, d-ribose, is a component of the ribonucleotides from which RNA is built, and so this compound is necessary for coding, decoding, regulation and expression of genes. It has a structural analog, deoxyribose, which is a similarly essential component of DNA. l-ribose is an unnatural sugar that was first prepared by Emil Fischer and Oscar Piloty in 1891.

Ribulosenoun

a ketopentose whose phosphate derivatives participate in photosynthesis

Ribulose

Ribulose is a ketopentose — a monosaccharide containing five carbon atoms, and including a ketone functional group. It has chemical formula C5H10O5.
