There are 4 forms of vitamin D, and the important ones are synthesized by the reaction between UV rays and cholesterol in our skin.

Vitamin B7 Biotin is synthesized in small amounts by gut bacteria.

Vitamin D is synthesized when modified Cholesterol molecules. . .
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.
Cholesterol is the precursor of bile acid, steroid hormones and vitamin D.
Vitamin D is not synthesized in the body when a person is confined to a dark cell for a long time. However, it can be obtained through diet or supplements. Vitamin D is primarily synthesized in the skin in response to sunlight exposure, so lack of sunlight would hinder its natural production in the body.
Vitamin D is synthesized when modified Cholesterol molecules. . .
Vitamin D would not be synthesized in a person confined to a dark cell for a long time. Vitamin D is primarily synthesized in the skin in response to sunlight exposure. Without access to sunlight, the body would not be able to produce vitamin D naturally.
Vitamin D is synthesized in the skin with the help of sunlight.
