JEE AdvancedChemistryBiomoleculesNumerical+4 / −1
A linear octasaccharide (molar mass =1024 g mol−1=1024 \mathrm{~g} \mathrm{~mol}^{-1}=1024 g mol−1) on complete hydrolysis produces three monosaccharides: ribose, 2-deoxyribose and glucose. The amount of 2-deoxyribose formed is 58.26%(w/w)58.26 \%(\mathrm{w} / \mathrm{w})58.26%(w/w) of the total amount of the monosaccharides produced in the hydrolyzed products. The number of ribose unit(s) present in one molecule of octasaccharide is \qquad. Use: Molar mass (\left(\right.( in g mol−1)\left.\mathrm{mol}^{-1}\right)mol−1): ribose =150,2=150,2=150,2-deoxyribose =134=134=134, glucose =180=180=180; Atomic mass (in amu): H=1,O=16\mathrm{H}=1, \mathrm{O}=16H=1,O=16
