Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C6H5OH. [5] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH).
This article is about the class of organic compounds containing a phenol group. For the parent compound, see Phenol. In biochemistry, naturally occurring phenols are natural products containing at least one phenol functional group. [ 1 ][ 2 ][ 3 ] Phenolic compounds are produced by plants and microorganisms. [ 4 ]
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the ...
Phenol (C 6 H 5 OH) is a water-soluble compound consisting of a phenyl group (-C 6 H 5) bonded to a hydroxyl group (-OH). Phenol extraction is a widely used technique for purifying nucleic acid samples from cell lysates. [1] To obtain nucleic acids, the cell must be lysed, and the nucleic acids separated from other cell components.
A polyphenol antioxidant is a hypothesized type of antioxidant studied in vitro. Numbering over 4,000 distinct chemical structures mostly from plants, such polyphenols have not been demonstrated to be antioxidants in vivo. [1][2][3] In vitro at high experimental doses, polyphenols may affect cell-to-cell signaling, receptor sensitivity ...
Phenol coefficient. The Phenol coefficient, is now largely of historical interest, although the principles upon which it is based are still used. [1] It is a measure of the bactericidal activity of a chemical compound in relation to phenol. When listed numerically, the figure expressing the disinfecting power of a substance by relating it to ...
Chemical structure and properties. Phenol red exists as a red crystal that is stable in air. Its solubility is 0.77 grams per liter (g/L) in water and 2.9 g/L in ethanol. [1] It is a weak acid with p Ka = 8.00 at 20 °C (68 °F). A solution of phenol red is used as a pH indicator, often in cell culture.
Scientists have used a food coloring dye used in Doritos and other products to create mice with see-through skin, a low-cost way to assess the body's internal operations. Before you start ...
