ribo-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Origin: Formed within English, by compounding. Etymons: ribose n., -o- connective.

Etymology: < rib- (in ribose n.) + -o- connective.Found in a small number of formations, apparently earliest in the 1920s in ribonucleotide n. Compare German ribo- (1935, in Riboflavin riboflavin n., or earlier).

Biochemistry.

Containing ribose; associated with ribose. Chiefly forming the names of compounds and macromolecules containing ribose. See also riboflavin n., ribonucleic acid n., etc.
