What is Which structure of Protein is not denatured after heating upto100 degree? and explain in detail?
Primary structure of protein is not denatured after heating upto100 degree. Heat coagulation result in loss of higher level of structures other than primary structure. Difference between various protein structures Features 1o 2o 3o 4o Bond Covalent/ Peptide/ Amide Hydrogen- bond (H-bond) S~S HydrophobicHydrogenIonic HydrophobicH-bondIonic Functional activity Absent Absent Present Present Denaturation Retained because peptide bond is very strong.
