Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken and/or new bonds formed. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, usi ...

Momordicine
A momordicine is any of several compounds found in the bitter melon vine, ''Momordica charantia''. They are glycosides of cucurbitane derivatives.Daniel Bisrat Mekuria, Takehiro Kashiwagi, Shin-ichi Tebayashi, and Chul-Sa Kim (2006)"Cucurbitane Glucosides from ''Momordica charantia'' Leaves as Oviposition Deterrents to the Leafminer, ''Liriomyza trifolii''". ''Z. Naturforsch.'', volume 61c, pages 81–86 They include * Momordicine II * Momordicine IV, 7-''O''-''D''-glucopyranosyl-3,23-dihydroxycucurbita-5,24-dien-19-al Momordicine II and IV can be extracted from the leaves of ''M. charantia'' by methanol. They have been found to deter egg-laying of the leaf mining fly (''Liriomyza trifolii'') at a combined concentration of 96 µg/cm2.

Ethanol
Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a hydroxyl group). Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, the active ingredient in alcoholic drinks. Ethanol is naturally produced by the fermentation process of sugars by yeasts or via petrochemical processes such as ethylene hydration. It has medical applications as an antiseptic and disinfectant. It is used as a chemical solvent and in the synthesis of organic compounds, and as a fuel source. Ethanol also can be dehydrated to make ethylene, an important chemical feedstock. As of 2006, world production of ethanol was , coming mostly from Brazil and the U.S. Etymology ''Ethanol'' is the systematic name defined by the Interna ...
