Alpha-gal syndrome (AGS), also known as alpha-gal allergy or mammalian meat allergy (MMA), [1] is a type of acquired allergy characterized by a delayed onset of symptoms (3–8 hours) after ingesting mammalian meat. The condition results from past exposure to certain tick bites and was first reported in 2002.
α-Galactosidase ( EC 3.2.1.22, α-GAL, α-GAL A; systematic name α-D-galactoside galactohydrolase) is a glycoside hydrolase enzyme that catalyses the following reaction: [1] Hydrolysis of terminal, non-reducing α- D -galactose residues in α- D -galactosides, including galactose oligosaccharides, galactomannans and galactolipids
Galactose-α-1,3-galactose, commonly known as alpha gal and the Galili antigen, is a carbohydrate found in most mammalian cell membranes. It is not found in catarrhines , [ 1 ] including humans, who have lost the glycoprotein alpha-1,3-galactosyltransferase ( GGTA1 ) gene.

This galactose molecule is called the H antigen. [28] [29] [30] Blood type A, B, AB, and O differ only in the sugar (red molecule in the illustration) linked with the penultimate galactose. For blood type B, this linked sugar is an α-1‐3‐linked galactose. Using α-GAL, this terminal galactose molecule can be removed, converting RBC to type O.
Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
Raffinose can be hydrolyzed to D-galactose and sucrose by the enzyme α-galactosidase (α-GAL), an enzyme synthesized by bacteria found in the large intestine. α-GAL also hydrolyzes other α-galactosides such as stachyose, verbascose, and galactinol, if present. In plants, raffinose plays a significant role in stress responses, particularly ...
A segment of galactomannan showing mannose backbone (below) with a branching galactose unit (top) Galactomannans are polysaccharides consisting of a mannose backbone with galactose side groups, more specifically, a (1-4)-linked beta-D-mannopyranose backbone with branchpoints from their 6-positions linked to alpha-D-galactose, (i.e. 1-6-linked alpha-D-galactopyranose).
