Without changing the size of the shot glass, however, the amount of alcohol in a shot can go as high as 95%, or 2.85 standard drinks. This means, for instance, that if you have one shot of 190-proof Everclear, you have consumed 2.85 times as much alcohol as you would if you had one shot of 72-proof whisky.
Pigments that contribute to skin color are called carotene, a yellowish hemoglobin, in blood vessels (pink-red), and melanin (black, brown, red). Darker skins are dominated by melanin, which is produced from the amino acid tyrosine, by pigment cells (melanocytes) in the skin.igments that contribute to skin color are called carotene, a yellowish hemoglobin, in blood vessels (pink-red), and melanin (black, brown, red).

Melanin is produced by special cells called melanocytes. More melanin is produced when the skin is not exposed to sunlight. Melanin ranges in color from yellow to brown to black. The stratum basale cells phagocytize the melanin produced by the melanocytes and it accumulates within them. Freckles and moles are seen where melanin is concentrated in one spot.
