<prompt> The Pentose sugar in nucleic acid is:RibuloseRiboseXyluloseXylase  <response>: Ribose: Ref 204-R.S.7thPentoses D. Ribose is a constituents of nucleic acid RNA: also as constituents of certain coenzyme eg. FAD, NAD, coenzyme A D-2 deoxyribose is constituent of DNA Phosphate esters of ketopentoses - D-ribulose and D-xylulose occurs as intermediates in HMP-shunt L-xylulose is a metabolite of D-glucuronic acid and is excreted in urine of humans affected with a hereditary abnormality in metabolism called Pentosuria L-fucosa methyl pentose occurs in glycoproteins D-lyxose: forms a constituent of lyxoflavin isolated from human heart muscle whose function is not clear.
