Question: what is vitamin a for
I found the following answer on Google: In general, carnivores are poor converters of ionine-containing carotenoids, and pure carnivores such as cats and ferrets lack 15-15'-dioxygenase and cannot convert any carotenoids to retinal (resulting in none of the carotenoids being forms of vitamin A for these species).
Is that a correct answer? Yes or no.
