Long protein chain folded upon itself like a hollow woolen ball and gives us a 3-dimensional view of a protein belongs to
1. Primary structure
2. Secondary structure
3. Tertiary structure
4. Quaternary structure
Which of the following statements is not correct about proteins?
1. The first amino acid of all the proteins is also known as N-terminal amino acid
2. In proteins, only right handed helics are observed
3. - helics are tertiary structures of proteins
4. Primary structure of a protein dictates its secondary and tertiary conformations
Identify the incorrect statement regarding the structure of proteins:
| 1. | They are heteropolymers containing strings of amino acids. |
| 2. | The first amino acid in the primary structure is the N-terminus amino acid |
| 3. | Only left helices are observed in proteins |
| 4. | Tertiary structure is absolutely essential for many biologic functions of the proteins |

(1)Act as hormones
(2)act as enzymes
(3)act as genetic material
(4)fight against infections

1. Alpha helix
2. Beta pleated sheet
3. Triple helix
4. Icosahederon
The quaternary structure of a protein:
| 1. | Consists of 4 subunits - hence the name quaternary |
| 2. | Is unrelated to the function of the protein |
| 3. | Both (a) and (b) |
| 4. | Depends on the 1° structure of subunits |
