| Proteins are made up of the chemical composition of Hydorgen, Oxygen, Nitrogen and Carbon. Nitrogen is used for growth. | The chemical composition of proteins is element -> amino acid-> polypeptide chain. Two examples of amino acids are Cysteine and Glycine. |
| Essential amino acids cannot be made in the body. We can only get them from food. Examples- Valine, lyceine, luecine, methonine, tryptophan, isoleucine, Proline, Cysteine. | |
| Protein structure Primary-order and sequence- draw basic chain with shapes give examples Secondary-further linking-disulphide link and hydrogen bond. Give examples for protein this happens in. Tertiary-further cross-links; 3D shape- 2 types fibrous and globular. Examples. | Classification Simple- plant-LBV (prolamines and glutelins) and animal-HBV (fibrous and globular) eg’s Conjugated- non-protein material on chain (lipoprotein, lecithin in egg) |
| Functions Structural-growth and repair Physiologically active-produce hormones, enzymes, antibodies Nutrients-essential amino acids; excess energy | The sources of protein are from animal and plant. Animal proteins tend to have a higher biological value than plant proteins. This is why animal proteins are knows as hbv and plant proteins are known as lbv. |
