Monomer - ANSWER✔✔ A simple compound whose molecules can join together
to form polymers
Cation - ANSWER✔✔ A positively charged ion
Anion - ANSWER✔✔ A negatively charged ion
primary protein - ANSWER✔✔ linear sequence of amino acids
secondary protein structure - ANSWER✔✔ coiling or folding of a polypeptide due
to H-bonding between amino acids
tertiary structure - ANSWER✔✔ The third level of protein structure; the overall,
three-dimensional shape of a polypeptide due to interactions of the R groups of the
amino acids making up the chain.
quaternary structure - ANSWER✔✔ The fourth level of protein structure; the
shape resulting from the association of two or more polypeptide subunits.
Polymer - ANSWER✔✔ A long molecule consisting of many similar or identical
monomers linked together.
ionic bond - ANSWER✔✔ A chemical bond resulting from the attraction between
oppositely charged ions.
covalent bond - ANSWER✔✔ A chemical bond that involves sharing a pair of
electrons between atoms in a molecule
