In female elephants, the two compounds 3-ethyl phenol and 2-ethyl 4,5 dimethylphenol have been detected in urine samples. [70] Temporal glands secretion examination showed the presence of phenol, m-cresol and p-cresol (4-methyl phenol) during musth in male elephants. [71] [72] [73] p-Cresol and o-cresol are also components of the human sweat.
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).
Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction. The paper also initiated the development of the planetary Rutherford model of the atom and eventually the Bohr model. Rutherford scattering is now exploited by the materials science community in an analytical technique called ...
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.
Folin–Ciocalteu reagent. The Folin–Ciocâlteu reagent (FCR) or Folin's phenol reagent or Folin–Denis reagent, is a mixture of phosphomolybdate and phosphotungstate used for the colorimetric in vitro assay of phenolic and polyphenolic antioxidants, also called the gallic acid equivalence method (GAE). [1] It is named after Otto Folin ...
Phenol red was used by Leonard Rowntree and John Geraghty in the phenolsulfonphthalein test to estimate the overall blood flow through the kidney in 1911. [9] It was the first test of kidney function and was used for almost a century but is now obsolete. The test is based on the fact that phenol red is excreted almost entirely in the urine.
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 ...
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 ...
