      Not very understandable for me. I find it very difficult to read through the accents...especially without official captions.

    My understanding is that the nuclear thyroid hormone (T3) receptor is a dimer and requires both vitamin A (form?) in combination with T3 for activation. Have you come across this information? Thyroid function is critical for hormonal and metabolic health. I recall learning about the thyroid hormone dimeric structure but I can't seem to find the reference again. Thank you.

  • @susanstewart1402
    @susanstewart1402 Рік тому

    Thank you for the succinct, thorough biochemistry overview. Could night blindness, and other symptoms of vitamin A deficiency, actually be zinc deficiency? Retinol DH and Retinal DH are both zinc-dependent enzymes. Some medical practitioners find that night-blindness responds better to a good dietary supplement of zinc (such as zinc picolinate) than to supplementation with vitamin A. Many areas of the world have low levels of zinc in the soil. Zinc is also found to be highly absorbable in meat sources which may have a relationship to protein synthesis as well. China, in particular is a country with both low zinc soil as well as low dietary meat consumption. Do you have any observations regarding the zinc vs vitamin A deficiency question?

    • @susanstewart1402
      @susanstewart1402 Рік тому

      Based on a brief search just now, I see that many areas of Africa also have low zinc in the soil. I always wondered why vitamin A deficiency would be such a problem in Africa given that their diet is very high in beta carotene foods. Interesting isn't it?
