Alkaloid - Wikipedia [1] 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 bacteria, fungi, plants, and animals [3]
Alkaloid | Definition, Structure, Classification | Britannica 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
What is Alkaloids? - Health Benefits 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
Alkaloid - an overview | ScienceDirect Topics Alkaloids are defined as a group of naturally occurring chemical compounds that mostly contain basic nitrogen atoms [1] Alkaloid molecules are extremely important for biomedical science
Alkaloids in food: a review of toxicity, analytical methods, occurrence . . . Alkaloids are naturally occurring nitrogen-containing compounds that are found in plants, fungi, bacteria and animals (Cushnie et al , 2014) The presence of nitrogen atoms in their structures is responsible for their alkaline nature, and Fig 1 shows the structures of some main alkaloids
The role of alkaloids in natural products chemistry Alkaloids are a class of naturally occurring organic compounds that are primarily composed of nitrogen atoms, typically within a heterocyclic ring structure
Alkaloids | SpringerLink This chapter addresses the complex field of alkaloids, their definition and classification, as well as their significance in nature and industry Despite nearly 50 years of discussion, a uniform definition for alkaloids remains difficult due to their diversity of
Alkaloid - New World Encyclopedia Alkaloids are usually derivatives of amino acids, and many have a bitter taste They are found as secondary metabolites in plants (such as potatoes and tomatoes), animals (such as shellfish), and fungi In many cases, they can be purified from crude extracts by acid-base extraction
Analysis of alkaloids (indole alkaloids, isoquinoline alkaloids . . . There are three central types of alkaloids: (1) true alkaloids, (2) protoalkaloids, and (3) pseudoalkaloids True alkaloids and protoalkaloids are produced from amino acids, whereas pseudoalkaloids are not derived from these compounds
