Protein Organization

Question 1

How many levels of organization are there?

Answer 1

Four; Primary, Secondary, Tertiary, and Quaternary

Question 2

Primary Structure

Answer 2

• linear sequence of amino acids linked by peptide bonds (backbone of polypeptide chain)
• polar peptide bonds make hydrogen bonding possible between C=O and N-H

Question 3

Secondary Structure

Answer 3

• polypeptide forms a coil-like shape (alpha helix shape)
• polypeptide forms a folded-fan shape (beta pleated shape)

Question 4

Tertiatry Structure

Answer 4

• three-dimensional structure from complex folding
• ## hydrophobic effect on peptide bonds and r qroups interact in polypeptide chain

Question 5

Quatenary Structure

Answer 5

• proteins compose of more than one polymer chain of amino acids
• multiple polypeptide with their one structure that chain together
