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.
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.
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).
The Beutler test, also known as the fluorescent spot test, [1] is a screening test used to identify enzyme defects. [2] [3] [4] Uses. It can be used in screening for:
A galactosemia test is a blood test (from the heel of the infant) or urine test that checks for three enzymes that are needed to change galactose sugar that is found in milk and milk products into glucose, a sugar that the human body uses for energy. A person with galactosemia does not have one of these enzymes.
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
