Secondary proteins structure is characterized by:
a. interactions between side chains of AA
b.overall structure of polypeptide chain
c.coiling for folding of polypeptide backbone
d.the unique sequence of aa
e. strong covalent bonds called disulfide bridges

can anyone give examples of each.. orwhere they belong, because its hard to wiki and get a straight forward answer. disulfide bridges i thought were in peptidoglycan.. but ia m probably wrong. If any one could explain each of the choices it would be of great help.

the answer is C.

i believe proteins have 4 diff types.
2ndary is called alpha and beta ****.

out of my head:
primary: the unique sequence of aa
secondary: coiling for folding of polypeptide backbone
Tertiary:interactions between side chain and strong covalent between disulfide
Last is interaction between polypeptide chains like hemoglobin.

doc, btw, will give u much nicer explanation than this😛

I would same the same as above.

Plus.
Quateranary structure would be a very large structures such as globular proteins where it folds over itself to compact into smaller structure.

From what I understand a quateranary structure requires 2 or more 3` structures..

Also proteins can display activity once they reach the 3` structure (remember form dictates function)

so hemoglobin has disulfide bridges since its a protein.??? achilles??

I doubt "EVERY" protein has disulfide bridges. However, disulfide bridges are a characteristic of a tertiary protein structure.

And, who cares/knows if hemoglobin, a specific protein, has disulfide bridges. :|
