Fig. 2.27. Representative HPLC chromatograms of carotenoids found in the plasma of green iguanas after being fed with a carotene-deficient diet (a) or a diet supplemented with /3-carotene (b), can-thaxanthin (c) and /f-apo-8 -carotenoic acid ethyl ester (d) recorded at 450 nm. Enumerated peaks are (1) lutein (21.3min) (2) zeaxanthin (22.2min) (3) undefined peak co-eluted with zeaxanthin (22.2min) (4) canthaxanthin (23.1min) and (5) apo-8 -carotenoic acid ethyl ester (26.7min).

Hatchling green iguanas. Iguana iguana, recognize kin by the odor of their feces, but also by their body odor (Werner et al, 1987).

Hoshita et al. have shown that liver microsomes from the green iguana, in which the major biliary bile salt is tauroallocholate, convert 7a,12a-dihydroxycholest-4-en-3-one (XVII) into 5a-cholestane-3a,7a,12a-triol (XVIII) rather than into 5)8-choles-tane-3 ,7a,12a-triol (VIII) which is involved in cholic acid biosynthesis [164]. On the basis of this result and that obtained from studies with carp liver [151], it can be assumed that 5a-bile acids and alcohols are formed from cholesterol by a modification of the biosynthetic pathway to the corresponding 5y8 isomers in which the only difference is the stereospedfic saturation of the A double bond of the intermediate XVII.
