Amino Group
correct ans:- Consists of hydrogen and nitrogen atoms (NH3+)

Carboxyl Group
correct ans:- Consists of carbons and oxygens (COO-)

R Group
correct ans:- The variable group within an Amino Acid

Amino Acid Backbone
correct ans:- Consists of the Amino Group (NH3+) the Carboxyl Group (COO-) and the Alpha
Carbon that bonds to a Hydrogen

Monomer
correct ans:- A small chemical unit that makes up a polymer

Polymer
correct ans:- A long molecule consisting of many similar or identical monomers linked
together.

Polypeptide
correct ans:- A polymer (chain) of many amino acids linked together by peptide bonds.

Peptide Bond
correct ans:- Bonds that connect amino acids.

Primary Protein Structure
correct ans:- Sequence of amino acids forming a protein or polypeptide chain, the most
basic element of its structure.

Alpha Carbon
correct ans:- The central carbon atom of each amino acid

Secondary Protein Structure
correct ans:- Shape formed by hydrogen bonding of amino acid back bone- usually an alpha
helix or beta sheet

Tertiary Protein Structure
correct ans:- The three-dimensional shape of a polypeptide due to interactions of the R
groups of the amino acids by covalent bonds

Quaternary Protein Structure
correct ans:- Multiple polypeptide subunits held together by R group interactions

Beta Pleated Sheet
correct ans:- A secondary structure found in proteins in which "pleats" are formed by
hydrogen bonding between atoms on the backbone of the polypeptide chain
