A simplified scheme of analysis is presented for the determination of free and esterified cholesterol, the phospholipids, and the neutral fats (triglycerides) of blood serum. The hydroxamic acid reaction is used to determine total esterified fatty acids. The phospholipids are determined after acid digestion of a trichloroacetic acid precipitate of protein-phospholipid, and both total and free c...

Reactive oxygen species, along with reactive nitrogen species, may play an important role in the pathogenesis and progress of many diseases, including cancer, diabetes and sickle cell disease. It has been postulated that hydroxyurea, one of the main treatments in sickle cell disease, achieves its activity partly also through its antioxidant properties. A series of hydroxyurea derivatives of L- ...

Long-chain alkanehydroxamic acids adsorb on the native oxides of metals and formed oriented selfassembled monolayers (SAMs). This study examined SAMs of hydroxamic acids on the native oxides of copper, silver, titanium, aluminum, zirconium, and iron. These SAMs were characterized usingwettability, X-ray photoelectron spectroscopy (XPS), and polarized infrared external reflectance spectroscopy (...

Fatty hydroxamic acid derivatives were synthesized using Lipozyme TL IM catalyst at biphasic medium as the palm kernel oil was dissolved in hexane and hydroxylamine derivatives were dissolved in water: (1) N-methyl fatty hydroxamic acids (MFHAs); (2) N-isopropyl fatty hydroxamic acids (IPFHAs) and (3) N-benzyl fatty hydroxamic acids (BFHAs) were synthesized by reaction of palm kernel oil and N-...
