WebJun 1, 2003 · Thereafter, sepiapterin (6-lactoyl-7,8-dihydropterin) accumulates as yellow pigment in xanthophores, together with 7-oxobiopterin, isoxanthopterin and 2,4,7-trioxopteridine. Sepiapterin is the key intermediate in the formation of 7-oxopteridines, which depends on the availability of enzymes belonging to the xanthine oxidoreductase family. WebTwo of the pigment classes commonly found in animal integument are carotenoids and pterins. Carotenoids are well known in physiology, behavior, and evolution studies for their roles in visual communication as condition-dependent signals (Kodric- . Pterins are much less known but may also serve a signaling role in visual communication .
