Document Summary
Proteins: contain c,o,h,n and usually some sulfur also, polymers of amino acids, about 20 different kinds. Amino acids: all amino acids have the same basic structure, unbranched; long chains, amino acids are bonded together through condensation reactions, form "peptide bonds , polar covalent bonds, structurally complex, unlike carbohydrates and lipids, uniquely shaped; globular. Denaturation and renaturation: the 3-d shape of proteins is often very important to how they function, a change in a single amino acid may cause the final molecule to have a different shape, called denaturation. Nucleic acids: polymers of nucleotides (5 kinds) all nucleotides have the same basic structure. Nucleic acids: are polymers of nucleotides bonded together through condensation reactions. Similarities : large molecules are polymers of smaller subunits the reactions which join these monomers are condensation reactions the reactions which breakdown the polymers are hydrolysis reactions.
