Alkaloids are a broad class of naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. [2] Alkaloids are produced by a large variety of organisms including …

2025年1月4日 · Alkaloid, any of a class of naturally occurring organic nitrogen-containing bases. Alkaloids have diverse and important physiological effects on humans and other animals. Well-known alkaloids include morphine, strychnine, quinine, ephedrine, and nicotine.

2024年7月30日 · Alkaloids are a diverse group of naturally occurring organic compounds that predominantly contain basic nitrogen atoms. These compounds are primarily found in plants and are known for their significant pharmacological effects on humans and animals.

Alkaloids are secondary metabolites originally defined as pharmacologically active compounds, primarily composed of nitrogen (Croteau et al., 2000; Ziegler & Facchini, 2008). They are synthesized from one of the few common amino acids: lysine, tyrosine and tryptophan.

2018年5月14日 · Alkaloids are natural, organic substances that are predominantly found in plants and normally contain at least one nitrogen atom in their chemical structure. Their basic (alkaline) nature has led to the term alkaloids.

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.

2023年2月3日 · Alkaloids can be defined as naturally occurring large groups of pharmacologically active nitrogen-containing secondary metabolites present in plants, microbial, or animals. The term alkaloid was derived from alkali and the Greek word oeides which means like. It means these are water-soluble bases.

Alkaloids meaning can be defined as any naturally occurring organic nitrogen-containing class bases. Alkaloids contain diverse and essential physiological effects on humans and on other animals. A few of the well-known alkaloids can be given as strychnine, morphine, ephedrine, quinine, and nicotine. Alkaloids originated from the word alkali.

Alkaloids are a large cluster of molecules found in Mother Nature all over the world. They are all secondary compounds and collection of miscellaneous elements and biomolecules, derived from amino acids or from transamination.

2025年2月3日 · The meaning of ALKALOID is any of numerous usually colorless, complex, and bitter organic bases (such as morphine or caffeine) containing nitrogen and usually oxygen that occur especially in seed plants and are typically physiologically active.
