A white, crystalline, nitrogenous substance formed in the decomposition of albuminous matter by pancreatic digestion, by the action of boiling dilute sulphuric acid, and by putrefaction. It is also found as a constituent of various tissues and organs, as the spleen, pancreas, etc., and likewise in the vegetable kingdom…

and other sources, as a colorless, spongy, amorphous material. It is so called because by decomposition it yields levulose. [Written also lævulin.]
