Straight chain fatty acids,
mono basic, aliphatic, terminating in a single carboxyl group and of reduced
hydrogen content than their saturated counterparts, constitute the ethylenic
family of unsaturated fatty acids. They are of considerable importance since
linkage with other chemical radicals is readily accomplished at the double
bond positions. Multiple unsaturation is found in almost all natural occurring
vegetable and animal fats. Research in recent years has shown them to be of
great significance.
Double bonds are susceptible to oxidation so that stability is a factor to
be reckoned with (especially polyunsaturated compounds) when researching unsaturated
fatty acids or their corresponding esters.
Highly purified unsaturated compounds prepared in our laboratory are always
flushed several times with nitrogen, sealed in glass under vacuum and stored
under cold conditions until ready for shipment.
Nu-Chek suggests that when your shipment is received, they should be stored
under cold conditions until ready for use. Once vial is opened protect with
N2 and use as soon as possible.
NU-CHEK
ALSO PRODUCES AN UNSATURATED SERIES OF FATTY ACIDS AND ESTER HOMOLOGS. AS
SEEN BELOW, NU-CHEK PREPARES MANY OMEGA 3 AND OMEGA 6 POLYUNSATURATED FATTY
ACIDS. BELOW ARE A FEW OF NU-CHEK'S CORE PRODUCTS, ARACHIDONIC ACID, EICOSAPENTAENOIC
ACID, DOCOSAPENTAENOIC ACID, AND DOCOSAHEXAENOIC ACID. ALL ARE >99% BY
GC AND TLC ANALYSIS. FOR MORE INFORMATION ON OUR POLYUNSATURATED SERIES PLEASE

Indeed, the use of soap-cosmetics and oil lubricants dates back thousands of years. While we at Nu-Chek do not profess to go back quite that far, we would like to say that we have been synthesizing pure gylceride standards for the scientific community for over thirty years.
The general procedure for all our triglyceride preparations is well exemplified in Nu-Chek's Triolein. Our starting material is chromatographically pure Methyl Oleate (isolated from the best virgin olive oil available) which is interesterified for the production of crude Triolein. To assure geometric stability of cis double bonds, the material is further purified by such physical techniques as low temperature crystallization and column chromatography. The final purity is followed both by gas liquid and thin layer chromatography.
Other triglycerides are prepared in a similar manner commencing with the particular oil which contains the best concentrates of the specific ester required.
