Alkaloids are naturally occurring toxic amines produced by plants mainly as a defense mechanism to protect themselves against herbivores. The main toxic effects of alkaloids result in disturbances of the central nervous system, digestive processes, reproduction, and the immune system.
alkaloid, Basic ( see base) organic compounds of plant origin, containing combined nitrogen. Alkaloids are amines, so their names usually end in “ine” (e.g., caffeine, nicotine, morphine, quinine). Most have complex chemical structures of multiple ring systems. They have diverse, important physiological effects on humans and other animals ...
Jun 28, 2020 · Alkaloids are nitrogen-containing natural products found in bacteria, fungi, animals, and plants with complex and diverse structures. The widespread distribution of alkaloids along with their...
Nov 13, 2019 · Alkaloids are a huge group of naturally occurring organic compounds which contain nitrogen atom or atoms (amino or amido in some cases) in their structures. These nitrogen atoms cause alkalinity of these compounds. These nitrogen atoms are usually situated in some ring (cyclic) system.
Jan 1, 2015 · Alkaloids can act as defense compounds in plants, being efficient against pathogens and predators due to their toxicity. Fast perception of aggressors and unfavorable environmental conditions, followed by efficient and specific signal transduction for triggering alkaloid accumulation, are key steps in successful plant protection.
Jun 28, 2020 · Alkaloids are nitrogen-containing natural products found in bacteria, fungi, animals, and plants with complex and diverse structures. The widespread distribution of alkaloids along with their wide array of structures makes their classification often difficult.
Jun 22, 2021 · There are the alkaloids we love as spices (capsaicin, piperine, and the Murraya alkaloids), those we fear as toxins (batrachotoxin, strychnine, and aconitine), those which affect perceptions in the brain (psilocin, N, N -dimethyltryptamine, and ibogaine), and there is caffeine, the global stimulant of coffee, tea, maté, and guarana.
