| Phenols are a subgroup of alcohol in which the hydroxyl groups are attached directly to the carbon atoms of a ring structure. |
| The trajectories of movement of the hydroxyl and hydroxonium ions are cycloids. |
| The presence of two hydroxyl groups permits the formation of hydrogen with water, thereby favoring miscibility with the latter. |
| Glycerol is a polyhydroxy alcohol containing three carbon atoms and three hydroxyl groups. |
| When this hydroxyl group is then methylated to give there is a very significant, 3000-fold, decrease in inhibitor binding. |
| Water always contains small quantities of two ions, hydronium ions and hydroxyl ions. |
