1 Most structurally & functionally diverse group : involved in almost everything enzymes (pepsin, DNA polymerase) structure (keratin, collagen) carriers & transport (, aquaporin) cell communication signals (insulin & other hormones) receptors defense (antibodies) movement (actin & myosin) storage (bean seed proteins) Structure monomer = amino acids 20 different amino acids polymer = polypeptide protein can be one or more polypeptide chains folded & bonded together large & complex molecules complex 3-D shape Rubisco H 2 O growth hormones Amino acids Structure central carbon amino group carboxyl group (acid) R group (side chain) variable group different for each amino acid confers unique chemical properties to each amino acid like 20 different letters of an alphabet can make many words (proteins) H O H N C C OH H R Oh, I get it! amino = NH 2 acid = COOH Effect of different R groups: Nonpolar amino acids nonpolar & hydrophobic Effect of different R groups: Polar amino acids polar or charged & hydrophilic Why are these nonpolar & hydrophobic? Why are these polar & hydrophillic? 1
2 Ionizing in cellular waters H+ donors Ionizing in cellular waters H+ acceptors Sulfur containing amino acids Form disulfide bridges covalent cross links betweens sulfhydryls stabilizes 3-D structure H-S S-H Building proteins Peptide bonds covalent bond between NH 2 (amine) of one amino acid & COOH (carboxyl) of another C N bond You wondered why perms smell like rotten eggs? dehydration synthesis H 2 O peptide bond Building proteins Polypeptide chains have direction N-terminus = NH 2 end C-terminus = COOH end repeated sequence (N-C-C) is the polypeptide backbone can only grow in one direction Protein structure & function depends on structure 3-D structure twisted, folded, coiled into unique shape pepsin collagen 2
3 Primary (1 ) structure Order of amino acids in chain amino acid sequence determined by gene (DNA) slight change in amino acid sequence can affect protein s structure & its function even just one amino acid change can make all the difference! Sickle cell anemia Just 1 out of 146 amino acids! lysozyme: enzyme in tears & mucus that kills bacteria I m hydrophilic! But I m hydrophobic! Secondary (2 ) structure Local folding folding along short sections of polypeptide interactions between adjacent amino acids H bonds weak bonds between R groups forms sections of 3-D structure -helix -pleated sheet Secondary (2 ) structure Tertiary (3 ) structure Whole molecule folding interactions between distant amino acids hydrophobic interactions cytoplasm is water-based nonpolar amino acids cluster away from water H bonds & ionic bonds disulfide bridges covalent bonds between sulfurs in sulfhydryls (S H) anchors 3-D shape Quaternary (4 ) structure More than one polypeptide chain bonded together only then does polypeptide become functional protein hydrophobic interactions collagen = skin & tendons 3
4 Protein structure (review) 1 amino acid sequence peptide bonds determined by DNA 2 R groups H bonds R groups hydrophobic interactions disulfide bridges (H & ionic bonds) 3 multiple polypeptides hydrophobic interactions 4 Protein denaturation Unfolding a protein conditions that disrupt H bonds, ionic bonds, disulfide bridges temperature ph salinity alter 2 & 3 structure alter 3-D shape destroys functionality In Biology, size doesn t matter, SHAPE matters! some proteins can return to their functional shape after denaturation, many cannot EAT X! Let s build some Macromolecule Review Carbohydrates monosaccharide energy raw materials energy storage structural compounds glycosidic bond glucose, starch, cellulose, glycogen Lipids Structure / building block glycerol, fatty acid, cholesterol, H-C chains energy storage membranes hormones fat, phospholipids, steroids ester bond (in a fat) 4
