Wide variety of substances and essential in minute quantities. Initially fish are very different for vit requirements, but they have very similar metabolisms, similar enzymes, identical metabolic reactions. Since vitamins are coenzymes, they should require vitamins in the same amount. However, the their requirements can be higher than mammals. If deficient or excess, there is improper development (early in development) Bind to nuclear receptor to form dimer and affect expression of genes. Body stores retinal in the liver but this form is transformed into. Guides the development and orientation of the body. Important in development when deficient and in excess. Creates dimer with retinoic acid to affect gene expression. Missing an electron so it is very reactive. Will steal another electron from another molecule to create another free radical. A double bond within a molecule is the weak point. Pufa are prone to free radical damage = rancidity. Vit e is able to become a free radical.
