AQA A-Level Biology - Proteins

AQA A-Level Biology - Proteins 1. Amino Acid - A monomer that will join with other amino acids to form a protein 2. Dipeptide - Two amino acids bonded together via a peptide bond 3. Polypeptide - Many amino acids bonded together via peptide bonds 4. Protein - A combination of polypeptides 5. Amine Group - -NH2, a basic group where the amino part of amino acid comes from 6. Carboxyl Group - -COOH, an acidic group where the acid part of amino acid comes from 7. R Group - A side group that can be comprised of different chemical groups 8. Condensation Reaction - The reaction that allows the formation of a peptide bond 9. Process of a Condensation Reaction - A H+ is removed from the amine group, and the OH- is removed from the carboxyl group on the other amino acid. This forms water and a dipeptide. 10. Primary Structure - The linear amino acid sequence of the polypeptide chain
