Metabolism:. In order to survive, the human body needs the nutrients found in food. These nutrients, which perform a number of life-sustaining functions in the body, are divided into 6 main categories: carbohydrates, proteins, fats, vitamins, minerals and water. Each has a unique function in the normal growth and repair of the body.. Starches, Cellulose, Gums. and Pectins. Starches. – . most abundant complex carbohydrate in diet.. Composed of glucose .

( Starch, Glycogen, Cellulose); for example of poly saccharides . . Simple types of carbohydrates such as ;Glyceraldehyde,. Dihydroxyacetone,(Triose;n=3) . . SIMPLE & COMPLEX.. They are called carbohydrates because, at the chemical level, they contain carbon, hydrogen and oxygen.. Unlike essential amino acids and fatty acids, there are no essential carbohydrates. This means we can obtain everything we need nutritionally from other food sources, so carbs are not necessary to maintain life..
