Pentadecanoic acid is a saturated fatty acid. Its molecular formula is CH3(CH2)13COOH. It is rare in nature, being found at the level of 1.2% in the 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.[4] Pentadecanoic acid also occurs in hydrogenated mutton fat.[5]

Pentadecanoic acid may increase mother-to-child transmission of HIV through breastfeeding.[6]
