Carausius morosus

The end products of tryptophan metabolism in the stick insect, Carausius morosus, are the ommochromes ommin and xanthommatin (58) in the epidermis, and kynurenic acid (53) in the feces. During larval development of this insect kynurenic acid (53) is the major end product of tryptophan metabolism (Table V) (109,110). Additionally, this insect contains five pteridines (Table VI), of which leucopterin (68), xanthopterin (65), and isoxanthopterin (67) are the origin of the yellow-white color of the insect (111). 

Carotenoid Metabolism and Metabolites. A scheme has been proposed for the metabolism of /3-carotene by the stick insect Carausius morosus to give /3,/8-caroten-2-ol (20) and /3,/3-carotene-2,2 -diol (21) via intermediate 2-oxo-compounds such as (27)." " Feeding experiments have shown that in the goldfish lutein [ S, -carotene-3,3 -diol (150)] and zeaxanthin are converted into astaxanthin (60) whereas /8-carotene and canthaxanthin (130) are not. Further studies suggest that marine red fish such as sea bream cannot oxidize the 3- and 4-positions of the /8-ring.
