Notes from NEET topper
Structure of Proteins:
-
Proteins have a hierarchical structure consisting of four levels:
-
Primary Structure: The linear sequence of amino acids in a protein chain.
-
Secondary Structure: Local folding patterns in a protein chain, often forming alpha helices or beta sheets.
-
Tertiary Structure: The overall three-dimensional arrangement of the protein’s polypeptide chain, including the folding of secondary structures.
-
Quaternary Structure: The arrangement of multiple protein subunits (polypeptide chains) in a complex protein with multiple subunits.
