The document describes the four protein conformations: primary, secondary, tertiary, and quaternary. It also states the first law of thermodynamics as energy can be transferred and transformed, and the second law as entropy where energy transfer and transformation results in increased disorder.

 Name and describe the 4 protein
conformations.
 State
the first and second laws of
thermodynamics.

2. Answers
 Primary – unique sequence of amino acids
 Secondary – coils and folds resulting from the
hydrogen bonds
 Tertiary – overall shape resulting from interactions
on the (R groups) side chains
 Quaternary – overall protein structure of two or
more polypeptide chains – functional molecule
 1st– Energy can be transferred and transformed
 2nd – Entropy – energy transfer/transformation
results in increased disorder
