    In this lecture I'll cover everything that you need to know for your exams about fat soluble vitamins. Go ahead pull up the visual. How do we remember, what the fat soluble vitamins are? Well I hope you remembering the big fat naked lady on the beach. Because we have a little "n" then we start with "A." So A is retinol or retinoic acid or retinal. In the fat soluble vitamins, again we generally go with the latter. But I'm giving you the names so you have some associations. But depending on it's form, it could have a different name so it can get a little confusing. So I really recommend keeping track of the latter name for these vitamins. Retinol is involved in the retina and rhodopsin. So it's involved in the pigment of rhodopsin. And thus, associated with night vision. We also know that vitamin A is involved in skin issues. Treatment with retina or retinoic acid. It is common for acne and the renewal of the skin. And it's also involved in cell differentiation. So in cell differentiation, I have an example here where vitamin A can be used as a treatment for acute myeloid leukemia. What happens in that case is, we end up with a number of progenitor cells or over abundance of progenitor cells that are not maturing. And this has to do with a retinol receptor. And the retinol receptor is defective. So there is some thought that treatment with additional vitamin A can increase the production of these erythrocytes and mast cells and so on and so forth. Maturation of the red blood cell, I mean, white blood cell line. So next we'll look at vitamin A deficiency. Clearly you can guess what those deficiencies result in based on the role...
