Role of Carbohydrates in Food

Abstract

Carbohydrates are polyhydroxyaldehydes (aldoses) or polyhydroxyketones (ketoses) composed of C, H, and O. They are classified into monosaccharides, oligosaccharides, and polysaccharides. Glucose is an aldohexose and the most important monosaccharide in humans, used as fuel by cells.
