The given structure of protein corresponds to:

Step-by-step solution

Structure of protein has upto 4 levels : 1 . Primary structure - Linear sequence of amino acids with 2 terminals : A. N- terminal : On left side and is represented by the first amino acid (also known as N- terminal amino acid). B. C- terminal : On right side and is represented by the last amino acid (also known as C- terminal amino acid). - This structure appears like a thread and is non-functional. 2 . Secondary structure - The above mentioned thread is folded in staircase like helix at some portions and in some o
