Hydrogenation is a chemical reaction between molecular hydrogen and an element or compound, ordinarily in the presence of a catalyst. The reaction may be one in which hydrogen simply adds to a double or triple bond connecting two atoms in the structure of the molecule or one in which the addi...
Hydrogen peroxide is chemical commonly used as a mild antiseptic in its diluted form to treat cuts and scrapes, killing germs at the site of an injury before bandaging the wound. It also has several uses around the home, primarily as a stain fighting and cleansing agent.Answer and Explanation...
Explain what is meant by molecules having an ionic bond, a covalent bond, and a polar bond. How does this make the molecules different in terms of their chemical behavior? Two hydrogen atoms interact to form a hydrogen molecule. Classify the following statements that ...
Apolipoprotein E4 (APOE4) is the strongest known genetic risk factor for late-onset Alzheimer’s disease (AD). Conditions of stress or injury induce APOE expression within neurons, but the role of neuronal APOE4 in AD pathogenesis is still unclear. Here
The agents which lead to induction in cultured human skin fibroblasts fall into two categories: (a) those which are oxidants or can generate active intermediates (ultraviolet A radiation, hydrogen peroxide, menadione, and the tumor promoter, 12-O-tetradecanoylphorbol-13-acetate); (b) agents which...
However, they did not relate the inhibition only to the production of lactic and acetic acids, but again to the combined action of a wide range of compounds. A similar approach was done by Le Lay et al. (2016), who suggested a weak antifungal effect of hydrogen peroxide and ethanol ...
Dihydrogen monoxide is some layman's obvious attempt to try and fabricate a scientific name for water, but didn't know the basic principles of naming compounds! The correct 'scientific' name for water is hydrogen oxide! H2O is a 2 element, nonmetal-nonmetal compound and the prefixes mon-, ...
Upon opening, SOC channels promote calcium entry through the plasma membrane (PM), a major mechanism for Ca2+ influx.6,7 So far, two major molecular components of the SOC channel signalling pathway have been identified: stromal interaction molecule 1 (STIM1) and Orai1.8,9 STIM1 serves as ...
hydrogen peroxide; Xylenol Orange; catalase; semiquinone radical; cytotoxicity; SKOV-3; PEO11. Introduction Hydrogen peroxide (H2O2) is an oxidizing compound mainly used in industry for bleaching cotton, other textiles and wood pulp, as a rocket propellant and for cosmetic and medicinal purposes [...
Apart from searching for new structures of potential drugs, there is a second approach based on a combination of two or more well-known pharmacophores into one molecule with synergistic activities. Nasr et al. [13] described synthesis and antimicrobial effects of tiophene, acrylamide, aryl...
