Primary sequence of amino acids
Secondaryis shape formed by amino acids, when amino acids bend
and twist to form a stable shape common form= a helix!
Tertiary overall shape of polypeptide chain, weak bonds( mainly
hydrogen but sometimes ionic/sulphide bridges) form
Globular proteins= enzymes denature@ high temperatures
Quaternary how polypeptides…
