                                Did you know the skin produces up to 90% of the body's vitamin D? This is only possible because of a crucial compound called 7-dehydrocholesterol, which is used for synthesizing this essential nutrient when exposed to sunlight. Beyond its role as a provitamin, this vital molecule has other important functions within the body and is a key diagnostic marker for a rare genetic disorder.
