PiperinePiperine is an alkaloidextracted from the plant, Piper nigrum. Responsible for the pungency of black pepper, it is used in food flavorings as a spice, in fragrances, as an insecticide, and as an animal pest repellent. Along with its isomerchavicine, piperine from black pepper and long pepper has pungency effects via activation of TRPV1. Piperine also inhibits CYP2J2. It has been used in some forms of traditional medicine.
Black pepperBlack pepper (Piper nigrum) is a floweringvine in the family Piperaceae, cultivated for its fruit (the peppercorn), which is usually dried and used as a spice and seasoning. The fruit is a drupe (stonefruit) which is about 5 mm (1⁄4 in) in diameter (fresh and fully mature), dark red, and contains a stone which encloses a single pepper seed.
SolenopsinSolenopsin is a lipophilicalkaloid with the molecular formula C17H35N found in the venom of fire ants (Solenopsis). It is considered the primary toxin in the venom and may be the component responsible for the cardiorespiratory failure in people who experience excessive fire ant stings. Structurally solenopsins are a piperidine ring with a methyl group substitution at position 2 and a long hydrophobic chain at position 6.
Thomas Anderson (chemist)Thomas Anderson (2 July 1819 – 2 November 1874) was a 19th-century British chemist. In 1853 his work on alkaloids led him to discover the correct formula/composition for codeine. In 1868 he discovered pyridine and related organic compounds such as picoline through studies on the distillation of bone oil and other animal matter.
AmineIn chemistry, amines (, UK also ) are organic compounds that contain carbon–nitrogen bonds. Amines are formed when one or more hydrogen atoms in ammonia are replaced by alkyl or aryl groups. The nitrogen atom in an amine possesses a lone pair of electrons. Amines can also exist as heterocyclic compounds.
Heterocyclic compoundA heterocyclic compound or ring structure is a hydrocarbon-based cyclic compound that contains at least one heteroatom as member(s) of its ring(s). Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles. Examples of heterocyclic compounds include all of the nucleic acids, the majority of drugs, most biomass (cellulose and related materials), and many natural and synthetic dyes.
AlkaloidClass of naturally occurring chemical compoundsThe first individual alkaloid, morphine, was isolated in 1804 from the opium poppy (Papaver somniferum).Alkaloids are a broad class of naturally occurringorganic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large variety of organisms including bacteria, fungi, plants, and animals.
Organic compoundOrganic compounds are a subclass of chemical compounds of carbon. Little consensus exists among chemists on the exact definition of organic compound; the only universally accepted definition is the quasi-tautological "organic compounds are the subject matter of organic chemistry". Generally, any large chemical compound containing a carbon–hydrogen or carbon–carbon bond is accepted as an organic compound.
Methylene bridgeIn chemistry, a methylene bridge is part of a molecule with formula −CH2−. The carbon atom is connected by single bonds to two other distinct atoms in the rest of the molecule. A methylene bridge is often called a methylene group or simply methylene, as in "methylene chloride" (dichloromethaneCH2Cl2). As a bridge in other compounds, for example in cyclic compounds, it is given the name methano.
HumanSpecies of hominid in the genus HomoHumans (Homo sapiens, meaning 'thinking man' or 'wise man') are the most abundant and widespread species of primates, characterized by bipedalism, minimal body hair, and large, complex brains enabling the development of advanced technology, culture, and language.
SpermSperm (pl.: sperm or sperms) is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one). Sperm cells contribute approximately half of the nuclear genetic information to the diploid offspring (excluding, in most cases, mitochondrial DNA).
Piper (plant)Piper, the pepper plants or pepper vines, is an economically and ecologically important genus in the family Piperaceae. The genus contains about 1,000–2,000 species of shrubs, herbs, and lianas, many of which are dominant species in their native habitat. The diversification of this taxon is of interest to understanding the evolution of plants.*As an Amazon Associate I earn from qualifying purchases.
