Carbohydrates

About 50% of diet. Provides energy. Protein sparing action. Normal fat metabolism. Three types.

Disaccharides

Double sugars. Hydrolysis to monosaccharides. Examples are sucrose maltose and lactose

Polysaccharides

Complex carbohydrates containing combinations of monosaccharides. Examples include starch dextrin cellulose and glycogen

Glycogen

Glucose that is stored in the liver and muscles. Approximately 1/2 day supply of energy is stored as glycogen in the liver and muscles

Fiber

Indigestible parts of plants; absorbs water in large intestine, helping to create soft stool.

Cellulose

May lead to osteomalacia which then can evolve into osteoporosis

riboflavin B2

essential for carbohydrate fat and protein metabolism. Necessary for tissue maintenance. And healthy eyes

vitamin b6

Essential for protein metabolism and absorption, aids in the release of glucose from glycogen, amino acids present in excessive amounts can be converted to those in which the body is temporarily deficient
