Thus, the two substrates of this enzyme are (−)-menthol and NADP +, whereas its 3 products are (−)-menthone, NADPH, and H +. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD + or NADP + as acceptor. The systematic name of this enzyme class is (−)-menthol:NADP ...
Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol has been demonstrated to cause a subjective nasal decongestant effect without any objective decongestant action, and administration of menthol via a nasal inhaler in humans has also been shown to cause nasal congestion ...
This process suggested that carbon dioxide and hydrogen could be reacted to produce methanol. [9] German chemists Alwin Mittasch and Mathias Pier, working for Badische-Anilin & Soda-Fabrik (BASF), developed a means to convert synthesis gas (a mixture of carbon monoxide , carbon dioxide , and hydrogen ) into methanol and received a patent.
One-dimensional crystalline nanowires are then grown by a liquid metal-alloy droplet-catalyzed chemical or physical vapor deposition process, which takes place in a vacuum deposition system. Au-Si droplets on the surface of the substrate act to lower the activation energy of normal vapor-solid growth.
Menthone was first synthesized by oxidation of menthol in 1881, [6] [needs update] [7] before being found as a component in essential oils in 1891. [ citation needed ] Of the isomers possible for this chemical structure (see below), the one termed l -menthone —formally, the (2 S ,5 R )- trans -2-isopropyl-5-methylcyclohexanone (see infobox ...
[15] [16] Menthol, hinokitiol and thymol are also used in oral hygiene products. Thymol also has antiseptic and disinfectant properties. [17] Volatile monoterpenes produced by plants can attract or repel insects, thus some of them are used in insect repellents, such as citronellol, eucalyptol, limonene, linalool, hinokitiol, menthol and thymol ...
Medicine: Organic synthesis plays a vital role in drug discovery, allowing chemists to develop and optimize new drugs by modifying organic molecules. [9] Additionally, the synthesis of metal complexes for medical imaging and cancer treatments is a key application of chemical synthesis, enabling advanced diagnostic and therapeutic techniques. [10]
