A) Galactose
B) Gluconic acid
C) P-methyl galactoside
D) Sucrose
Correct Answer: A
Solution :
[a] Reducing sugar is any sugar that has an aldehyde group or is capable of forming one in solution through isomerisation. Reducing monosaccharides include glucose, fructose, glyceraldehyde and galactose. Many-disaccharides, like lactose and maltose also have a reducing form, as one of the two units may have an open- chain form with an aldehyde group. However, sucrose and trihalose in which the anomeric carbons of the two units are linked together, are non reducing disaccharides since neither of the rings is capable of opening.
