Hydrolysis of sucrose (a non-reducing disaccharide) gives an equimolar mixture of glucose and fructose; D-ribose is a 5-carbon aldose sugar.

Glucose from sucrose: sucrose (a disaccharide of $\alpha$ -D-glucose and $\beta$ -D-fructose joined through their anomeric carbons) is hydrolysed by dilute acid or the enzyme invertase to give an equimolar mixture of glucose and fructose (this mixture, being dextrorotatory sucrose turning into a laevorotatory-dominated mixture, is called 'invert sugar'):

$C_{12}H_{22}O_{11} + H_2O \xrightarrow{H^+\ or\ invertase} C_6H_{12}O_6\,(glucose) + C_6H_{12}O_6\,(fructose)$
