The similarity-based [4] virtual screening (a kind of ligand-based virtual screening) assumes that all compounds in a database that are similar to a query compound have similar biological activity. Although this hypothesis is not always valid, [5] quite often the set of retrieved compounds is considerably enriched with actives. [6]
Azoth – initially this referred to a supposed universal solvent but later became another name for Mercury. Bitumen – highly viscous liquid or semi-solid form of petroleum. Blende; Brimstone – sulfur; Flowers of sulfur – formed by distilling sulfur. Caustic potash/caustic wood alkali – potassium hydroxide, formed by adding lime to potash.
People who are sensitive to urushiol can also experience a similar rash from mangoes. Mangoes are in the same family (Anacardiaceae) as poison ivy; the sap of the mango tree and skin of mangoes has a chemical compound similar to urushiol. [41] A related allergenic compound is present in the raw shells of cashews. [42]
Chemical substance – Form of matter; List of alchemical substances; List of chemical elements; List of minerals – List of minerals with Wikipedia articles; List of named alloys; List of straight-chain alkanes; Polyatomic ion – Ion containing two or more atoms; Exotic molecule – a compound containing one or more exotic atoms
Flowers on the periphery are zygomorphic and the corolla has one large lobe (the so-called "petals" of a daisy are individual ray flowers, for example). Either ray or disk flowers may be absent in some plants: Senecio vulgaris lacks ray flowers [4] and Taraxacum officinale lacks disk flowers. [4] [5] The individual flowers of a pseudanthium in ...
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.
Compound Umbel – an umbel where each stalk of the main umbel produces another smaller umbel of flowers. Corymb – a grouping of flowers where all the flowers are at the same level, the flower stalks of different lengths forming a flat-topped flower cluster. Cyme – is a cluster of flowers where the end of each growing point produces a flower.
