WebThe simpler carbohydrates resemble water molecules in one important respect. Their primary hydrogen-bonding function comes from the hydroxyl group which can have both donor and acceptor properties (Box 13.1). For this reason, their hydrogen-bonding patterns have features in common with those of the ices and the high hydrates. WebIn a β pleated sheet, two or more segments of a polypeptide chain line up next to each other, forming a sheet-like structure held together by hydrogen bonds. The hydrogen bonds form between carbonyl and amino groups of backbone, while the R groups extend above and below the plane of the sheet ^3 3.
