Alpha-galactose allergy

Alpha-gal allergy or Alpha-gal syndrome also known as meat allergy or mammalian meat allergy (MMA) is a reaction to galactose-alpha-1,3-galactose (alpha-gal). The body is overloaded with innunoglobuline E (IGE) or contact with the carbohydrate.

The alpha-gal molecule is found in all mammals except apes, humans, and Old World monkeys.
