| An effect on the permeability of other small uncharged solutes such as monohydric alcohols, amides and acetone was not detectable. |
| Alcohols have one, two, or three hydroxyl groups attached to their molecules and are thus classified as monohydric, dihydric, or trihydric, respectively. |
| If a compound possesses only one hydroxyl group then it is said to be a monohydric alcohol. |
| Subsequently, the polyphenol was further separated into dihydric phenols and monohydric phenol. |
