Hydrogen bonds in biological molecules
WebEach molecule participates in a total of six hydrogen bonds. Two amino hydrogen atoms and one hydroxyl hydrogen atom participate in hydrogen bonds to other molecules and three nitrogen atoms (two in the ring and one in the long side-chain) participate in hydrogen bonds which have the hydrogen atom chemically bound to adjacent molecules.
