Volatile Cuprous and Silver Salts of Fatty Acids

Nature, 1948
IN a communication in Nature1, one of us (F. K.) reported on a volatile copper compound obtained by thermal decomposition of cupriformate. J. G. Maltby2 directed attention to the work of A. Angel and A. V. Harcourt3, according to whom cuprous acetate forms as a white sublimate when cupriacetate is heated.

Volatile fatty acids, “copulins”, in human vaginal secretions

Psychoneuroendocrinology, 1975
Abstract (1) In a double-blind study using a new tampon method, 682 samples of vaginal secretions were collected from 50 healthy young women attending a university. (2) Samples were analyzed by gas chromatography for the volatile fatty acids (C2-C6) that have sex-attractant properties in infra-human primates.

Volatile Fatty Acids in Portal Blood of Sheep

Nature, 1949
VOLATILE fatty acids—chiefly acetic, propionic and butyric acids—are formed as a result of the fermentation processes in the rumen of sheep and are absorbed through its wall. With the purpose of investigating the concentration of these acids and other constituents in the portal blood during a digestion cycle, that is, the 12-hour period after feeding ...

Volatile fatty acids in normal human physiological fluids

Clinica Chimica Acta, 1970
Abstract A relatively simple gas Chromatographic technique is described which makes possible the identification and quantitation of free volatile fatty acids containing up to 6 carbon atoms in physiological fluids. Values are shown for the concentrations of these acids in the urine, serum, cerebrospinal fluid, and sweat of normal human subjects.

Pretreatment of macroalgae for volatile fatty acid production

Bioresource Technology, 2013
In this study, a novel method was proposed for the biological pretreatment of macroalgae (Laminaria japonica, Pachymeniopsis elliptica, and Enteromorpha crinita) for production of volatile fatty acid (VFA) by anaerobic fermentation. The amount of VFA produced from 40 g/L of L.

VOLATILE FATTY ACIDS AND FATTY ACID COMPOSITION OF SILAGE SPECIES

2015
In this study, total fatty acid composition and volatile fatty acid of silage species in Turkey was determined by using Gas Chromatography (Shimadzu 15-A). Total lipids were extracted from the corn silage, alfalfa silage and figure silage samples by the method of Folch et al. Silage species were a total of 15 different fatty acids.

Volatile fatty acids in stored animal slurry

Journal of the Science of Food and Agriculture, 1978
AbstractVolatile fatty acids (VFAs) were measured in slurry stored in farm and laboratory conditions. All slurries from farm sources contained VFAs; acetic acid was predominant, followed by propionic, n‐butyric, iso‐butyric, iso‐valeric and n‐valeric. On average, pig slurry contained more total VFAs than did cow slurry.

Volatile Fatty Acid Production in Ruminants

2017
Volatile fatty acids (VFA) are important products of ruminal fermentation. The VFA are not only the major source of energy to the ruminant animals but also influence methane production in the rumen. Therefore it is important to understand mechanism controlling VFA production and to depict VFA production in a model.
