proteins

Question 1

what is the formation order of a protein?

Answer 1

amino acid

peptide

polypeptide

protein

Question 2

what are proteins comprised of and what does their shape determine?

Answer 2

C, H, O, N, S (only some)

shape determines function

Question 3

what is the general structure of an amino acid?

Answer 3

amino group, carboxyl group, unique side chain (R group)

Question 4

how can side chains be grouped?

Answer 4

non polar (hydrophobic)

polar (hydrophilic)

charged/ionic (hydrophilic)

Question 5

functions of proteins

Answer 5

antibodies

enzymes

messengers (hormones)

structural

transport/storage

Question 6

primary structure

Answer 6

linear chain of amino acids

dictates secondary and tertiary forms

Question 7

secondary

Answer 7

coils and folds due to h bonds within polypeptide backbone

beta sheet

alpha helix

Question 8

tertiary

Answer 8

3D folding to due interactions between side chains and AAs

Question 9

quaternary

Answer 9

association of two or more polypeptides

only in some proteins
