a reducing site of a carbohydrate is found anywhere that the carbohydrate has
a a carbon 6 not involved in a glycosidic linkage
b a carbon 4 not involved in a glycosidic linkage
c a carbon 3 not involved in a glycosidic linkage
d a carbon 1 not involved in a glycosidic linkage

Explanation:

A reducing sugar has a free - aldehyde or free - hemiacetal group. In a carbohydrate, the carbon 1 (anomeric carbon) when not involved in a glycosidic linkage can open up to form a free aldehyde group, making it a reducing site.

Answer:

D. A carbon 1 not involved in a glycosidic linkage
