The skin, liver, and kidneys participate in synthesizing the active form of vitamin D.
Yes. In presence of ultraviolet rays cholesterol in blood is converted into vitamin D. Witch get one hydrogen atom attached in liver and another in kidney to from active form of vitamin D.
Type your answer here... VItamin k is required by the liver to synthesize proteins for blood clotting purposes you get vitamin k from leafy greens or an injection.
I suppose that you think to vitamin A; but also vitamin D, vitamin B12, vitamin K are stored in liver.
No. human body can not synthesize vitamin B 12. You have to consume the same through your food only. Only non-veg food contains the most of the vitamin B 12 you get. Strict vegans should be given injections of vitamin B 12.
Vitamin D? No. Vitamin D is not manufactured, rather, it is chemically altered by UV rays on the skin, and thereby, capable of utilization by the liver, and then by the kidneys; the organ responsible for maintenance of calcium levels. Interestingly enough, however, the active form of vitamin D is plentiful in the western diet, and only about 5-10% of vitamin D is actually utilized by the UV ray induced alteration from the skin. The skin produces many substances, however, most substances are consider paracrine (affecting neighboring cells) rather than endocrine (affecting distant organ systems). More commonly, hormones or endocrine substances, affect the skin, causing pathologic states. An example of paracrine: - Inflammatory markers- Sites of trauma, or areas of potential infection; cells within the skin induce several chemicals that increase the migration of specialized cells of the immune system, as well as cells from the vasculature (platelts) and other cells that are responsible for healing - Endocrine: Insulin (acanthosis nigricans) immune complexes (vitiligo, bullae)
Humans are not primarily photosynthetic. Plants are. Plants use sunlight to synthesize chemicals that they need. They do not eat. Humans, in comparison, are omnivorous. We eat food to gain energy, so we do not need photosynthetic skin. However, we humans do synthesize vitamin D with the help of sunlight, so to that small extent we do engage in photosynthesis.
beef liver have small amounts of vitamin D.

epiderm cell
Because they don't get enough sunlight to synthesize it normally. So they need to take Vitamin D for that.
Vitamin D comes from sunshine exposure and works with the mineral calcium. "Sunshine vitamin" is the nickname for vitamin D because the human body produces vitamin D through exposure to the UV rays of the Sun.
Yes

Cells of our body synthesize Vitamin D in the presence of sunlight.
The sunshine rays allows one's body to get vitamin D
Vitamin d
Vitamin D is found in eggs, liver, milk, oily fish and margarine. Vitamin E -
Sun exposure and cholesterol. Sun exposure converts 7-dehydrocholesterol to previtamin D3, which is then converted to Vitamin D.
