Oleoylethanolamide (OEA) is an endogenous peroxisome proliferator-activated receptor alpha (PPAR-α) agonist.It is a naturally occurring ethanolamide lipid that regulates feeding and body weight in vertebrates ranging from mice to pythons.
Oleylamine reacts with carboxylic acid to form its carboxylate salt through an exothermic reaction. [8] [9] Its carboxylate salt can further condensate into amides through the loss of one water molecule. In the presence of acetic acid, oleylamin forms with DNA insoluble complexes with the radii of the particles equal 60–65 nm. [10]
Fatty amines are commonly prepared from fatty acids; which are themselves obtained from natural sources, typically seed-oils.The overall reaction is sometimes referred to as the Nitrile Process [3] and begins with a reaction between the fatty acid and ammonia at high temperature (>250 °C) and in the presence of a metal oxide catalyst (e.g., alumina or zinc oxide) to give the fatty nitrile.
The original toilet cleaner was invented by Harry Pickup (hence the origin of the name Harpic [2]), who was based in Roscoe Street, Scarborough, in North Yorkshire.He also invented Oxypic, which was a sealant used in cast iron heating systems, and patented the Lock & Lift circular manhole covers, which were used initially by the British Military.
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.

Examples are N‑tert‑butylhydroxylamine or the glycosidic bond in calicheamicin. N,O‑Dimethylhydroxylamine is a precursor to Weinreb amides. Similarly to amines, one can distinguish hydroxylamines by their degree of substitution: primary, secondary and tertiary.
When bleaching cotton-polyester blends, NMEA is used as a brightener. [5] By methylation of N-methylaminoethanol, dimethylaminoethanol and choline [(2-hydroxyethyl)-trimethyl-ammonium chloride] can be prepared. In the reaction of N-methylaminoethanol with fatty acids, long-chain N-methyl-N-(2-hydroxyethyl)amides are formed upon elimination of ...
