Positional distribution of isomers of monoenoic fatty acids in animal glycerolipids
Journal of Lipid Research, 1967 The distributions of the following monoenoic acids were determined [notation: (position of double bond)-(chain length): (no. of double bonds)]: 7-, 9-, and 11-16: 1; 7-, 9-, 11-, and 13-18:1 ; 9-, 11-, and 13-20:1 ; 9 + 11-22:1 and 13-22:1.

Journal of Lipid Research, 2012 Retinol (vitamin A) circulates at 1–4 μM concentration and is easily measured in serum. However, retinol is biologically inactive. Its metabolite, retinoic acid (RA), is believed to be responsible for biological effects of vitamin A, and hence the ...

Benchmark Studies on the Isomerization Enthalpies for Interstellar Molecular Species
Journal of Nigerian Society of Physical Sciences, 2023 With the well-established correlation between the relative stabilities of isomers and their interstellar abundances coupled with the prevalence of isomeric species among the interstellar molecular species, isomerization remains a plausible formation ...

Synthesis of isomers of eugenol
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1963 In connection with an investigation of the correlation between structure and reactivity of eugenol isomers, o-eugenol, 3-allyl-2-methoxyphenol and chavibetol were synthesized. A five-step synthesis was found to be most suitable for the preparation of 3-allyl-2-methoxyphenol.

Computer generation of isomers [PDF]
Computers & Chemistry, 1982 Abstract A computer program is developed for the enumeration of the isomers of polysubstituted compounds with b1 subtituents of the type 1, b2 subtituents of the type 2,.…, bn subtituents of the type n. The procedure is illustrated with octahedral molecules containing 4 kinds of subtituents (such as F, Cl, Br, and I) and the isomers of polysubtituted

‘Melatonin isomer’ in wine is not an isomer of the melatonin but tryptophan‐ethylester
Journal of Pineal Research, 2014 AbstractMelatonin is a neurohormone, chronobiotic, and antioxidant compound found in wine and deriving directly from grapes and/or synthesized by yeast during alcoholic fermentation. In addition, a melatonin isomer has been detected in different foods, wine among them.
