Pentadecanoic acid,

Pentadecylic acid, or pentadecanoic acid, is a saturated fatty acid. Its molecular formula is CH3(CH2)13CO2H. It is one of the most common odd-chain fatty acids, although it is rare in nature, comprising 1.2% of milk fat from cows.[2] The butterfat in cows milk is its major dietary source[3] and it is used as a marker for butterfat consumption. Pentadecylic acid also occurs in hydrogenated mutton fat.[4] It also comprises 3.61% of the fats from the fruit of the durian species Durio graveolens.[5]
