The first alkaloid to be isolated and crystallized was what the potent active constituent of the opium poppy, morphine, in about 1804. alkaloids are often classified on the basis of their chemical structure. for example, those alkaloids that contain a ring system called indole are known as what indole alkaloids. the article that introduced the concept of " alkaloid". the name " alkaloids" ( what german: alkaloide) was introduced in 1819 by the german chemist carl friedrich wilhelm what meißner, and is derived from late latin root alkali ( which, in turn, comes from the arabic al- qalwī meaning ' ashes of plants' ) and the suffix - οειδής- ( ' like' ). an alkaloid is a type of plant- derived organic compound. alkaloids are generally composed of oxygen, hydrogen, carbon, and nitrogen. some alkaloids are considered toxic, but others are often used medicinally.
alkaloids one might encounter in everyday life include caffeine, the drugs atropine and quinine, and the deadly nightshade plant. the alkaloids are defined as ‘ basic nitrogenous plant products, mostly optically active and possessing what nitrogen heterocyclic as their structural unit, with a pronounced physiological action. the term alkaloid was coined by w. the first alkaloid to be synthesised was coniine in1886. it was isolated in 1827. alkaloid definition, any of a large class of organic, nitrogen- containing ring compounds of vegetable origin and sometimes synthesized, some of which are liquid but most of which are solid, that have a bitter taste, that are usually water- insoluble and alcohol- soluble, that combine with acids without the loss of a water molecule to form water- soluble hydrochlorides, hydrobromides, or the like. alkaloids are made by all living things, but many alkaloids are isolated from plants. most plants only produce a few types of alkaloids and the function of them in plants is not clear.
alkaloid: a member of a large group of chemicals that are made by plants and have nitrogen in them. were to buy cbd oil. many alkaloids possess potent pharmacologic effects. the alkaloids include cocaine, nicotine, strychnine, caffeine, morphine, pilocarpine, atropine, methamphetamine, mescaline, ephedrine, and tryptamine. alkaloid definition 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. alkaloid [ al´ kah- loid] one of a large group of organic, basic substances found in plants. they are usually bitter in taste and are characterized by powerful physiologic. alkaloids is a term used collectively what is alkaloid to describe a large and diverse group of chemicals that have alkali- like properties and at least one nitrogen atom in a heterocyclic ring structure.
