Hydroxytyrosol
Hydroxytyrosol is an organic compound with the formula . It is a phenylethanoid, i.e. a relative of phenethyl alcohol. Its derivatives are found in a variety of natural sources, notably olive oils and wines. Hydroxytyrosol is a colorless solid, although samples often turn beige during storage. It is a derivative, formally speaking, of catechol. Hydroxytyrosol and its derivatives occur in olives and in wines. Occurrence Olives left, ester.html" ;"title="Oleuropein, bitter compound, an ester">Oleuropein, bitter compound, an ester of hydroxytyrosol found in green olive skin The olives, leaves, and olive pulp contain large amounts of hydroxytyrosol derivative oleuropein, more so than olive oil. Unprocessed, green (unripe) olives contain between 4.3 and 116 mg of hydroxytyrosol per 100 g of olives, while unprocessed, black (ripe) olives contain up to 413.3 mg per 100 g. The ripening of an olive substantially increases the amount of hydroxytyrosol. Processed olives, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methacrylic Anhydride
Methacrylic anhydride is a liquid which reacts with water exothermically. It can also react with hydroxyl and amino groups present in some organic compounds leading to covalent attachment of methacryloyl moieties. These functional groups could be successfully used either in subsequent polymerisation or reactions with thiols. For example, chitosan modified by methacryloylation exhibits better ability to adhere to mucosal surfaces ( mucoadhesion) due to its reactivity with thiols groups present in cysteine domains of mucins. Uses Methacrylic anhydride is used as an intermediate agent in plastics, material, and resin A resin is a solid or highly viscous liquid that can be converted into a polymer. Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, predominantly terpenes. Commo ... manufacturing.

Syringol
Syringol is the organic compound with the formula HO(CH3O)2C6H3. The molecule is a phenol, with methoxy groups in the flanking (2 and 6) positions. It is the symmetrically dimethylated derivative of pyrogallol. It is a colorless solid, although typical samples are brown owing to air-oxidized impurities. Together with guaiacol, syringol and its derivatives are produced by the pyrolysis of lignin. Specifically, syringol is derived from the thermal decomposition of the sinapyl alcohol component. As such, syringol is an important component of wood smoke. Syringyl/guaiacyl ratio Lignin, comprising a major fraction of biomass, is sometimes classified according to the syringyl component. Pyrolysis of lignin derived from sinapyl alcohol affords syringol. The conversion involves replacement of the propenyl alcohol substituent of the sinapyl alcohol by hydrogen. A high syringyl (or S) content is indicative of lignin from angiosperms. In contrast, pyrolysis of lignin from gymn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanillyl Alcohol
Vanillyl alcohol is derived from vanillin. It is used to flavor food. Chemistry Vanillyl alcohol can be produced by reducing vanillin with sodium borohydride under basic conditions, then quenching using a strong acid such as hydrochloric acid. See also * Anisyl alcohol * Guaiacol Guaiacol () is an organic compound with the formula C6H4(OH)(OCH3). It is a phenolic compound containing a methoxy functional group. Guaiacol appears as a viscous colorless oil, although aged or impure samples are often yellowish. It occurs wid ... References {{alcohol-stub Primary alcohols Phenols Phenol ethers ...

Molecular Formula
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and ''plus'' (+) and ''minus'' (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name since it does not contain any words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than chemical names and structural formulae. The simplest types of chemical formulae are called '' empirical formulae'', which use letters and numbers indicating the numerical ''proportions'' of atoms of ...
