Monohydric, mon-ō-hī′drik, adj. containing one atom of hydrogen.

Cholesterol and phytosterol are empirical names for certain closed-ring, monohydric alcohols which are found in relatively small amounts in all fats, the former term designating those found in animal fats and the latter those of plant origin.

Open-chain monohydric alcohols, higher members of the ethyl alcohol series, such as cetyl, C16H33OH, carnaubyl, C24H49OH, ceryl, C26H53OH, and melissyl, C30H61OH, are found in the esters which constitute the major proportion of the common waxes.

They are similar to fats in chemical composition, except that, instead of being glycerides, they are esters of monohydric alcohols of high atomic weight.

Field groups the solvents of pyroxyline into classes thus: Two of the monohydric alcohols; compound ethers of the fatty acids with monohydric alcohols, aldehydes; simple and mixed ketones of the fatty acid series.
