Document Summary

Atoms & ions | chemical bonding | water | acid & bases | organic compounds | carbohydrates | lipids | Proteins | enzymes | nucleic acids | atp. Proteins are made by building long chains of amino acids. The r side chain is attached to central carbon. Each r side chain has a different structure to it. Twenty different types of side chains (20 amino acids) Amino acids are linked together to form long chains. Linked together by peptide bonds a special covalent bond found in proteins. After the chains of amino acides are constructed, they can fold into more complex structures. Primary - exact sequence of amino acids before folding. Tertiary - folding results in complex 3d structures. Quaternary - multiple 3d subunits organized into a bigger structure. Carries oxygen in the blood- it"s made up of 4 specific 3d subunits. Proper protein function depends on correct 3d structure.
