R, R' and R'' are saturated or unsaturated chains. Thus, he described fats as combinations of fatty acids with a substance which adds water under the influence of alkali to form glycerin, this substance being analogous to alcohol. Later confirmation was given that natural fats and oil are formed of complex mixtures of various molecular species. This complexity can be deduced from the fatty acid analyses of purified triacylglycerols from vegetal or animal origin. These compounds, analogs of triacylglycerols, are found in liver oils from marine organisms, particularly elasmobranchs but are also found in mammalian tumor lipids .
Saponification cleaves the two esters bonds and frees monoalkyl glycerols .
