The final diversity step required that the masked anomeric hydroxyl group be. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'hydroxyl.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. The aminoethyl-photolinker AM resin was chosen because earlier studies had. 2018 More proof: Glycerin, one of the best moisturizers available, is a polyol, a type of alcohol with multiple hydroxyl groups. In this review, we describe the versatile applications of 4-fluoro-3-nitrophenyl azide, one of the oldest photolinkers used for photoaffinity labeling in the late 1960s. 2019 In the end, the team will end up with estimates of atmospheric hydroxyl concentrations that date back to about 1880. used photolinker to produce the desired chemical linkage upon their photo-irradiation. Finally, photolytic cleavage of the resin (XIII). Korey Haynes, Discover Magazine, 19 Mar. dimethoxytritylated at the aliphatic hydroxyl and attached through the phenol. The invention relates to a photolinker macromolecule comprising photoactivable groups and sulfur-containing groups, which is attached to a metallic substrate, and optionally covalently bonded to a ligand, and the use thereof in biosensor systems, microarrays, nanoparticles, nanoassemblies and microparticles useful in bioanalytics, or the pharmaceutical, or textile industry. Elizabeth Gamillo, Smithsonian Magazine, Seconding this theory, Ryugu also shows signs of being covered in hydroxyl, a material made up of hydrogen and oxygen. 2023 After each lightning flash, the researchers found the concentrations of hydroxyl and hydroperoxyl increased by thousands of parts per trillion, Science News reports. 2018 During photocatalysis, light is absorbed by photocatalysts that have the ability to create electron-hole pairs, which generate free hydroxyl radicals that are able to react with target pollutants and degrade them. It appears that the milk enhanced the cell uptake of stilbenoids with multi-hydroxyl groups and weakened the cell uptake of stilbenoids with methoxyl group. This study addresses the selection of photolinker and the adjustment of reaction conditions, such as the concentration of biomolecule applied, and irradiation time. 2020 The goal of this latest expedition, which is scheduled to return mid-February, is to see whether concentrations of an atmospheric molecule called hydroxyl, or OH, has changed over time since the industrial revolution. The use of photolinkers (photoactivatable heterobifunctional crosslinkers) is a popular method to attach biomolecules to polymer surfaces. 2020 Those measurements focused on a shorter, three-micron wavelength that was more ambiguous, unable to differentiate between a water molecule, which consists of two hydrogen atoms and one oxygen atom or hydroxyl, which has one hydrogen atom and one oxygen atom. Leonard David, Scientific American, 26 Oct. Recent Examples on the Web Previous studies have revealed that protons from the solar wind that bombards the moon can absorb electrons from materials at its surface, forming atomic hydrogen that then reacts with oxygen atoms from silicate rocks to make hydroxyl-a molecule just one hydrogen atom short of water.
