A saponifiable lipid is part of the ester functional group. They are made up of long chain carboxylic (of fatty) acids connected to an alcoholic functional group through the ester linkage which can undergo a saponification reaction. The fatty acids are released upon base-catalyzed ester hydrolysis to form ionized salt... | https://en.wikipedia.org/wiki/Saponifiable_lipid |
Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali . Typically aqueous sodium hydroxide solutions are used.

The saprobic system is a tool to measure water quality, and specifically it deals with the capacity of a water body to self-regulate and degrade organic matter. The saprobic system derives from so-called saprobes — organisms that thrive through degradation of organic matter, which is called saprotrophic nutrition .
