Origin of fatty acids

Milk Fat Origin of Fatty Acids and Influence of Nutritional Factors Thereon... 

The origin of fatty acids and civetone in panda is unknown. Based on four samples of bladder urine obtained between 1999 and 2003, which were not from the days of peak excretion, decanoic acid and traces of octanoic and dodecanoic acid were also detectable in bladder urine. In addition, civeton was also demonstrated in bladder urine. Those findings might rule out the possibility of an extra-renal source from acessory glands of the reproductive tract. Octanoic and decanoic acid were also detected in a cotton wool swab from the female s anal gland three days after urinary peak excretion.
