Abstract: | Background Carotenoids are pigment molecules produced mainly in plants and heavily exploited by a wide range of organisms higher up in
the food-chain. The fundamental processes regulating how carotenoids are absorbed and metabolized in vertebrates are still
not fully understood. We try to further this understanding here by presenting a dynamic ODE (ordinary differential equation)
model to describe and analyse the uptake, deposition, and utilization of a carotenoid at the whole-organism level. The model
focuses on the pigment astaxanthin in Atlantic salmon because of the commercial importance of understanding carotenoid dynamics
in this species, and because deposition of carotenoids in the flesh is likely to play an important life history role in anadromous
salmonids. |
