Objective Describe the bonds that cause a peptide to fold into a complex structure. Protein a type of large molecule, consisting of one or more chains of repeated elements, that builds structures or performs functions in an organism Protein a large molecule composed of one or more peptides folded into a complex structure charged charged nonpolar polar nonpolar polar nonpolar polar nonpolar primary secondary primary secondary tertiary disulfide bond (nonpolar covalent) disulfide bond (nonpolar covalent) cysteine cysteine nonpolar covalent bond alpha helix (1 turn) alpha helix (3 turns) alpha helix (2 turns) proinsulin disulfide bond proinsulin 1 helix 3 helices 2 helices proinsulin primary quaternary secondary tertiary Key Point The structure of a protein emerges from the interactions between R groups, as well as the interactions between R groups and water.
