The “primary structure” of a protein refers to:
1. coiling due to hydrogen bonding between amino acids
2. the alpha helix or pleated sheets
3. the side groups of the amino acids
4. the number and sequence of amino acids
1. they are linear chains.
2. they are polymers of peptide monomers.
3. successive amino acids are joined by peptide bonds.
4. they can assume many conformations.
An example of protein with quaternary structure is
1. Myoglobin
2. Hemoglobin
3. Keratin
4. All of these
| Statement I: | A protein is imagined as a line, the left end represented by first amino acid (C-terminal) and the right end represented by last amino acid (N-terminal). |
| Statement II: | Adult human haemoglobin, consists of 4 subunits (two subunits of \(\alpha\) type and two subunits of ẞ type.) |
