Protein
1 Composition
1.1 Carbon, hydrogen, oxygen & nitrogen
1.1.1 Arranged in small units called amino acids which are linked together to form chains
1.1.1.1 Digested into sigle amino acids which are easily absorbed
1.1.1.1.1 Used to make new cells or to repair damaged cells
2 Some of the amino acids in protein can only be taken into the body in the foods that we eat, these are essential amino acids - (10 essential amino acids for children)
2.1 High Biological Value (HBV) - contain more essential amino acids. - Mostly animal sources - meat, fish eggs, dairy, soya protein
2.1.1 Low Biological Value (LBV) - contain fewer essential amino acids and are cheaper to produce - mostly plant foods - pulses (beans, peas), Cereals (wheat, oats), Nuts, Bread, Pasta
3 Functions - growth of body cells e.g. blood, skin, bone. Repair of damaged cells. Heat and energy. Production of body chemicals such as hormones and enzymes.
