WGU C785 Biochemistry Unit2
Amino Group - Correct answer-Consists of hydrogen and nitrogen atoms (NH3+)
Carboxyl Group - Correct answer-Consists of carbons and oxygens (COO-)
R Group - Correct answer-The variable group within an Amino Acid
Amino Acid Backbone - Correct answer-Consists of the Amino Group (NH3+) the Carboxyl Group (COO-)
and the Alpha Carbon that bonds to a Hydrogen
Monomer - Correct answer-A small chemical unit that makes up a polymer
Polymer - Correct answer-A long molecule consisting of many similar or identical monomers linked
together.
Polypeptide - Correct answer-A polymer (chain) of many amino acids linked together by peptide bonds.
Peptide Bond - Correct answer-Bonds that connect amino acids.
Primary Protein Structure - Correct answer-Sequence of amino acids forming a protein or polypeptide
chain, the most basic element of its structure.
Alpha Carbon - Correct answer-The central carbon atom of each amino acid
Secondary Protein Structure - Correct answer-Shape formed by hydrogen bonding of amino acid back
bone- usually an alpha helix or beta sheet
Tertiary Protein Structure - Correct answer-The three-dimensional shape of a polypeptide due to
interactions of the R groups of the amino acids by covalent bonds
Products - Correct answer-The ending materials in a chemical reaction.

O- & NH3+ - Correct answer-ionic bond
SH +SH - Correct answer-disulfide bond
reducing agent - Correct answer-breaks disulfide bonds
OH and NH2 - Correct answer-hydrogen bond
Ch ch - Correct answer-non polar, hydrophobic
how can we break charged or Ionic bonds? - Correct answer-changes in pH or salt
how can we break polar (hydrogen) bonds? - Correct answer-changes in pH or salt
Quaternary Protein Structure - Correct answer-Multiple polypeptide subunits held together by R group
interactions
Beta Pleated Sheet - Correct answer-A secondary structure found in proteins in which "pleats" are
formed by hydrogen bonding between atoms on the backbone of the polypeptide chain
Alpha Helix - Correct answer-A spiral shape constituting one form of the secondary structure of proteins,
arising from a specific hydrogen-bonding structure.
Hydrophobic - Correct answer-Afraid of the water, wants to be on the inside
Hydrophilic - Correct answer-Water loving, wants to be on the outside
