1.	The structure in which all peptide chains are stretched out to full extension and laid side by sidethrough intermolecular hydrogen bonds is called ______(a) α-helix(b) β-pleated sheet(c) tertiary structure(d) quaternary structureI had been asked this question by my college director while I was bunking the class.My enquiry is from Biomolecules topic in chapter Biomolecules of Chemistry – Class 12
Answer» CORRECT answer is (b) β-pleated sheet For explanation I would say: β-pleated sheet is one of the secondary STRUCTURES of proteins formed due to intermolecular HYDROGEN bonding. The STRUCTURE resembles the pleated folds of DRAPERY and hence the name.
