Lecture 6 Organic Compounds - Proteins and Nucleic Acids A. Basic Structure of Proteins 1. Complex - Have carbon, hydrogen, oxygen, and nitrogen ο Many of them also have sulfer - Structures have different levels ο Quaternary (10), Secondary (20), Tertiary (30), Quaternary (40) ο Have a three-dimensional shape 2. Amino acid (fig. 3-16) - Monomer (building block) ο Central carbon atom C (everything else is attached to it) ο Hydrogen -H ο Carboxyl group -COOH ο Amino Group -NH2 ο Side Chain -R (whatever else is attached to the molecule) ο There are 20 amino acids 3. Peptide Bond (fig. 3-18) - H H | | H2N--C--COOH H2N--C--COOH | | R R - Polypeptide = 3 or more amino acids together - Protein = several peptides (functional unit) 4. Hypersensitivity - Your allergic reactions to proteins ο Because your proteins are unique, when you come in contact with another person's
