The last four peaks of GC represented the following compounds: Dodecanoic acid
methyl ester, Tetradecanoic acid methyl ester, 8,11,14-Eicosadienoic acid methyl ester and 9,10-Dihydroxy octadecanoic acid methyl ester.
Analytically pure dodecanoic acid
(AR) and acetone (AR) were purchased from Beijing Chemical Reagents Company.
Schmidt (1984) evaluated the influence of saturated fatty acids on spore germination of brown- and white-rot basidiomycetes and determined that caprylic or ocanoic (C8), pelargonic or nonanoic (C9), and decanoic (C 10) acids (100 ppm) destroyed spores of test fungi, whereas dodecanoic acid
(C12) was effective against brown-rot but not white-rot fungal spores.
Fatty acid composition of feed and soybean oil Fatty acids Feeds and soybean oil (% of total fatty acid) Concentrate Ryegrass hay Dodecanoic acid
All of the volatile hips oil compositions for these species were dominated by following components: vitispiran (isomer), [alpha]-E-acaridial, dodecanoic acid
, hexadecanoic acid, docosane (C22), _-ionone, 6-methyl-5-hepten-2-one, 2-heptanone, heptanal, myristic acid and linolic acid.
2000) identified propionic acid, butyric acid, decanoic acid, and dodecanoic acid
in aroma of two White grape varieties.

After 100 days, methyl ester dodecanoic acid
and methyl tetradecanoate were detected with a 94% match.
Comment on "Whole blood levels of dodecanoic acid
, a routinely detectable forensic marker for a genetic disease often misdiagnosed as sudden infant death syndrome (SIDS): MCAD deficiency" [Letter; Comment].
Of several chemicals positively identified at day 16, only dodecanoic acid
was found solely in the inoculated fermentation.
