title = "Refined structure of hipposudoric and norhipposudoric acids, pigments of the red sweat of the hippopotamus",
abstract = "The tautomeric structures of hipposudoric and norhipposudoric acids were investigated using a computational method. The results indicated that the most appropriate canonical structures for these compounds were different; hipposudoric acid possessed an enol form at the C9-carboxy group, while norhipposudoric acid had an enol form at the C5-oxo group.",
