Reducing sugar is any sugar (all monosaccharides, some disaccharides, oligosaccharides, and polysaccharides) that is capable of acting as a reducing agent because it contains free aldehyde group or free ketone group.
Aldehyde group or alkanal is an organic compound containing formyl group. The formyl group is a functional group consisting of a carbonyl center bonded to hydrogen and an R group. This group can be readily reduced to primary alcohol with the help of catalyctic hydrogenation either applied directly or by transfer hydrogenation.
Ketone group unlike aldehyde group does not have a hydrogen atome bonded to the carbonyl group but it can still be hydrogenated.
When the body perspires, it cools itself due to the high specific heat capacity of water. Perspiration produces a cooling effect.
