Question

Explain the primary structure of proteins.

Answer 1

Primary structure of proteins:

1. Primary structure of proteins is the sequence of constituent α-amino acid residues linked by peptide bonds.
2. Any change in the sequence of amino acid residues results in a different protein.
3. Primary structure of proteins is represented by writing the three-letter symbols of amino acid residues as per their sequence in the concerned protein.
4. The symbols are separated by dashes. According to the convention, the N-terminal amino acid residue is written at the left end and the C-terminal amino acid residue at the right end.
