UNSATURATED SERIES
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 REPARES MANY OMEGA 3 AND OMEGA 6 POLYUNSATURATED FATTY ACIDS.

ALL ARE >99% BY GC AND TLC ANALYSIS.

GLYCERIDES
The distribution of random fatty acids in naturally occurring fats and oils in the form of triglycerides dates back to antiquity.
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 geometricstability 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.

NU-CHEK HAS BEEN PREPARING GLC AND TLC STANDARDS FOR OVER 38 YEARS. WE START BY
PURIFYING EACH INDIVIDUAL FATTY ACID METHY LESTER TO >99%, THEN INCORPORATING THEM INTO
OUR STANDARDS. WE HAVE OVER 130 DIFFERENT STANDARDS TO CHOOSE FROM.
