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 the substance that gives skin, hair, and eyes their color. Melanin is also found in the light-sensitive tissue at the back of the eye (the retina), where it plays a role in normal vision. Melanocytes make two forms of melanin, eumelanin and pheomelanin.
