Explain the terms primary and secondary structure of proteins. What is the difference between α− helix and β− pleated sheet structure of proteins?
Explain the terms primary and secondary structure of proteins. What is the difference between α− helix and β− pleated sheet structure of proteins?
Primary structure of proteins proteins consist of one or more polypeptide chains. Each polypeptide is a protein contains amino acids joined with each other in a specific sequence. Secondary structure of proteins it refers to the shape in which a long polypeptide chain can exist.
α−helix structure β−pleated sheet structureA structure of twisting of all a polypeptide chainAll peptide chains are stretched out to nearlyformed by possible H−bonds into a rightmaximum extension and then laid side by sidehanded screw (helix) with the−NH group ofwhich are held together by intermoleculareach amino acid, and residue hydrogenhydrogen bonds. This structure resembles thebonded to the−CO−of an adjacent turn ofpleated folds of the drapery. Hence, calledthe helix.Hence, called α−helix.β−pleated sheet structure.
