MSH: Polyhydric alcohols having no more than one hydroxy group attached to each carbon atom. They are formed by the reduction of the carbonyl group of a sugar to a hydroxyl group.(From Dorland, 28th ed),CSP: all sugars are alcohols by virtue of their hydroxy groups, but this term applies to those which have gained a hydroxy group by reduction of a keto or acid group.
