WGU C785 Biochemistry Unit2 EXAM WITH CORRECT ANS

Amino Group Consists of hydrogen and nitrogen atoms (NH3+) Carboxyl Group Consists of carbons and oxygens (COO-) R Group The variable group within an Amino Acid Amino Acid Backbone Consists of the Amino Group (NH3+) the Carboxyl Group (COO-) and the Alpha Carbon that bonds to a Hydrogen Monomer A small chemical unit that makes up a polymer Polymer A long molecule consisting of many similar or identical monomers linked together. Polypeptide A polymer (chain) of many amino acids linked together by peptide bonds. Peptide Bond Bonds that connect amino acids. Primary Protein Structure Sequence of amino acids forming a protein or polypeptide chain, the most basic element of its structure. Alpha Carbon The central carbon atom of each amino acid Secondary Protein Structure Shape formed by hydrogen bonding of amino acid back bone- usually an alpha helix or beta sheet Tertiary Protein Structure The three-dimensional shape of a polypeptide due to interactions of the R groups of the amino acids by covalent bonds
