17. Denaturation of proteins results in __C. Destruction of hydrogen bondsDenaturation of proteins involves the disruption of the secondary and tertiary structures of the protein molecule, which are stabilized by hydrogen bonds. The primary structure, which is the sequence of amino acids, remains intact. The peptide bonds between amino acids are not broken during denaturation.18. Proteins that constitute keratin, collagen and elastin in body are known as __C. ScleroproteinsKeratin, collagen, and elastin are structural proteins that provide strength and support to tissues. They are classified as scleroproteins, which are proteins that provide structural support to cells and tissues.19. __ is a fatty acid which is NOT synthesized in the body and has to be supplied in the dietC. Linolenic acidLinolenic acid is an essential fatty acid, meaning it cannot be synthesized by the body and must be obtained through the diet. The other fatty acids listed can be synthesized by the body.20. __ is a phospholipid that acts as surfactant.C. LecithinLecithin is a phospholipid that acts as a surfactant in the body. It helps to reduce surface tension and prevent the coagulation of blood cells.
