Proteins and Enzymes

ID #1628

Among the forces that contribute to the tertiary structure of proteins, which one of the following is least frequently used? The choices were: Glycosidic Linkages, ionic bonds, hydrogen bonds, covalent bonds (Disulfide bridges) or Van der waals forces. I know that Disulfide bridges are covalent bonds that are involved in determining tertiary structures...but I'm not sure if there are a lot of specific cysteine side chains in them...my guess is that there are not a of specific cysteine side chains so they (disulfide bridges) are less likely used. Am I correct?

Yes, disulfide bridges are part of tertiary structure. And since they are dependent on cysteine amino acids, which is only 1 of 20, they aren't going to happen very often. So they are the least likely to be used of the choices given.
