HUMAN NUTRITION

Detailed explanation-1: -Simple Carbohydrates. Simple carbohydrates are grouped as either monosaccharides or disaccharides. Monosaccharides contain only one molecule; glucose, fructose, and galactose are all monosaccharides. Disaccharides contain two molecules; lactose, maltose, and sucrose are classified as disaccharides.

Detailed explanation-2: -Each of the three common monosaccharides is hexoses, containing 6 carbon, 12 hydrogen, and 6 oxygen molecules in slightly varied configurations. The three most common monosaccharides are glucose, fructose, and galactose.

Detailed explanation-3: -There are two major carbohydrate subgroups: simple and complex. Simple carbohydrates contain the monosaccharide and disaccharide groups. Monosaccharides are comprised of a single simple sugar unit, glucose, fructose, or galactose, and they cannot be broken down into simple sugar units.
