Hipposudoric acid is a red pigment found in the skin secretions of the hippopotamus;[1] although the secretions are often known as "blood sweat" (thus the name "hipposudoric", referring to "hippo sweat"), they are neither blood nor sweat.
Like its orange-colored analog norhipposudoric acid, hipposudoric acid functions both as a natural sunscreen and as an antimicrobial agent. It is derived from the oxidative dimerization of homogentisic acid.[2]
