Vinegar test Vinegar test Vinegar test is a cervical cancer testing method that uses acetic acid, a major component of vinegar. It has been found to be useful as an effective and inexpensive screening test. It has the potential, say researchers from the University of Zimbabwe and Johns Hopkins University, to improve the chances of preventing cancer in developing world. The technique, termed VIA (Visual Inspection with Acetic Acid)/Cryo, was endorsed by the World Health Organization in 2010. Vinegar is brushed on a woman’s cervix and precancerous spots turn white. These can be instantly frozen off with a metallic probe cooled with
Organic compound insulin—are manufactured industrially using organisms such as bacteria and yeast. Typically, the DNA of an organism is altered to express compounds not ordinarily produced by the organism. Many such biotechnology-engineered compounds did not previously exist in nature. A great number of more specialized databases exist for diverse branches of organic chemistry. The main tools are proton and carbon-13 NMR spectroscopy, IR Spectroscopy, Mass spectrometry, UV/Vis Spectroscopy and X-ray crystallography. Organic compound In chemistry, an organic compound is generally any chemical compound that contains carbon. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds
