Document Summary

Central carbon - alpha carbon- bonds to four different atoms or groups of atoms: a hydrogen atom, an amino functional group- nh2, cooh- a carboxyl functional group, a distinctive r group (side chain) Carboxyl group acts as an acid- can easily lose a proton to become coo- R-group/side chain- represent the part of the amino acid core structure that makes each of the. Vary from a single hydrogen atom to large structures containing carbon atoms linked into rings. Macromolecules- larger molecules made up of smaller molecular subunits joined together. Amino acids are the monomers that polymerize to form proteins. Peptide bond- the c-n covalent bond that results from a condensation reaction between a carboxyl group of one amino acid and the amino group of another. Polymers that contain 50 or more amino acids are called polypeptides. Primary structure- unique sequence of amino acids in a protein. Secondary structure- created in part by interactions between functional groups in the peptide-bonded backbone.
