Chapter 13, Problem 19E
Interpretation Introduction
Interpretation:
Alkaloids are to be defined.
Concept Introduction:
It is a class of nitrogenous organic compounds of plant origin, which has a notable action on humans. This class includes many drugs (morphine, quinine) and poisons (atropine). Although majority of alkaloids are basic in nature, there are some exceptions that show neutral and even slightly acidic properties.
