Sunlight and Vitamin D Synthesis. Exposure to the sunâs ultraviolet (UV) rays is required for vitamin D3 (cholecalciferol) to be produced. Vitamin D3 is synthesized in the skin once your unprotected skin receives exposure to sunlights UV rays. The sun emits three different types of radiation, UVA, UVB and UVC. The ozone layer is good at blocking all of the UVC radiation and most of the UVB, however, none of the UVA radiation.
NAD(H) is a relatively large and complex molecule, as coenzymes go. It is vitamin B3 (niacinamide) combined with a ribose (5-carbon sugar), a phosphate group and an adenine nucleotide (a DNA component). NAD(H) can be made in the liver and other cells from vitamin B3. coenzyme is the active, or working form of a vitamin. NADH is the reduced (electron-energy rich) coenzyme form of vitamin B3, while NAD is the oxidized (burned) coenzyme form of B3.
