The hydroxyl radical can damage virtually all types of macromolecules: carbohydrates, nucleic acids , lipids (lipid peroxidation) and amino acids (e.g. conversion of Phe to m-Tyrosine and o-Tyrosine). The hydroxyl radical has a very short in vivo half-life of approximately 10 −9 seconds and a high reactivity. [5]
In recent years, RTSH has upgraded TV studios and broadcasting equipment, launched a number of digital TV channels, added live online TV and radio streams, and has uploaded TV programs on YouTube. Their old YouTube channel with dozens of videos was shut down in June 2021, losing historical documentaries and a new one was created which holds ...
In chemistry, hydroxylation refers to the installation of a hydroxyl group (−OH) into an organic compound. Hydroxylations generate alcohols and phenols, which are very common functional groups. Hydroxylation confers some degree of water-solubility. Hydroxylation of a hydrocarbon is an oxidation, thus a step in degradation.
The corresponding electrically neutral compound HO • is the hydroxyl radical. The corresponding covalently bound group –OH of atoms is the hydroxy group . Both the hydroxide ion and hydroxy group are nucleophiles and can act as catalysts in organic chemistry .
Hydroxy can refer to: . In chemical nomenclature, the prefix "hydroxy-" shows the presence of a hydroxyl functional group (−OH).; An abbreviation for the medication hydroxyzine, which is commonly sold under the brand names Atarax, Ucerax, Serecid, and Vistaril.
