Protein Structure
BIology Based
Question | Answer |
---|---|
Three Levels | Primary, Secondary, teritiary |
Quaternary Structure | arises when two or more polypeptides join forming proteins. |
Primary Sructure | sequence of amino acids |
Secondary structure | regular pattern of twists/kinks of polypeptide chain, regularity because of hydrogen bonds forming between atoms of amino acid backbones of chain |
Two most common types of secondary structure | Alpha Helix (coils) and B pleated sheet (folds) |
Tertiary Structure | helices and sheets of secondary structure fold upon thmselves |
Collagen | Quaternary, fibrous protein of three polypeptides |
Hemoglobin | Quaternary, fibrous protein of four polypeptides |
