P 029 - Free radical transformations of hydroxyl-containing amino acids and related compounds in aqueous solutionsN-centered radicalsfree radical destructionserinethreonineglucosamineIt is well known that reactive oxygen species (ROS), generated via various enzymatic and non-enzymatic pathways, can cause ...
The hydroxyl radical, ·OH, is the neutral form of thehydroxideion.Hydroxyl radicalsare highly reactive and consequently short lived; however, they form an important part ofradical chemistry. Most notablyhydroxyl radicalsare produced from the decomposition of hydro-peroxides(ROOH) or, inatmospheric ch...
Amino acids are the building blocks of proteins. Both serine and threonine are amino acids containing the hydroxyl group. Serine Threonine There are several other functional groups in addition to -OH that give organic molecules their specific properties. Hydroxyl...
Additional investigations using penicillin-G aqueous solutions containing DOM showed that the deactivation efficiency was decreased, as expected. In contrast, the presence of bicarbonate/carbonate improved the deactivation efficiency, which implied that carbonate radicals are more efficient at breaking the β...

Molecularly well-defined Aza-CMP-Co catalysts, containing Co2+ active sites on a regular CMP matrix, provide an excellent platform for mechanistic studies. Aza-CMP-Co (exfoliated) showed the highest geometric current density but suffered from active site decomposition during catalysis. In addition, ...
Sodium periodate also reacts with 2-aminoethanol derivatives—compounds containing a primary amine and a secondary hydroxyl group on adjacent carbon atoms. Oxidation cleaves the carbon–carbon bond, forming a terminal aldehyde group on the side that had the original hydroxyl residue (Reaction 3.40)....

Useful as catalysts for the reaction of a polyisocyanate or a partially blocked polyisocyanate with a hydroxyl-containing compound are hydroxyl-containing organotins such as, for example, compounds of
As water-soluble compounds they are of preferred interest for dyeing hydroxyl- and amido-containing textile materials, in particular materials made of natural and regenerated cellulose and synthetic polyamide and polyurethane fibres, wool and silk. ...
