Leucomaines were thought to be alkaloids formed in living animal tissue, while ptomaines were believed to be produced during putrefaction after death. Both terms are now largely historical.
No. The term is archaic. Modern biochemistry uses specific names for individual alkaloids and metabolic products.
It represents a stage in the historical development of physiological chemistry, reflecting earlier classifications of nitrogenous compounds before modern analytical techniques.
