  2. Alpha-gal syndrome - Wikipedia

    en.wikipedia.org/wiki/Alpha-gal_syndrome

    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.

  3. Galactose-α-1,3-galactose - Wikipedia

    en.wikipedia.org/wiki/Galactose-α-1,3-galactose

    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.

  4. GLA (gene) - Wikipedia

    en.wikipedia.org/wiki/GLA_(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.

  5. Fabry disease - Wikipedia

    en.wikipedia.org/wiki/Fabry_disease

    Deficient activity of lysosomal alpha-galactosidase results in progressive accumulation of globotriaosylceramide (GL-3) within lysosomes, that is believed to trigger a cascade of cellular events. [15] The demonstration of marked alpha-galactosidase deficiency is the conclusive method for the diagnosis in homozygous males.

    If this second result is still in the normal range, the child is said to have passed their galactose challenge, and dietary galactose restrictions are typically relaxed or discontinued. If the second test shows elevated Gal-1P levels, the parent/guardian may be advised to resume galactose restriction for the child, and the challenge may be ...

  7. α-Galactosidase - Wikipedia

    en.wikipedia.org/wiki/Α-Galactosidase

    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

  8. Galactokinase - Wikipedia

    en.wikipedia.org/wiki/Galactokinase

    Galactokinase is an enzyme (phosphotransferase) that facilitates the phosphorylation of α-D-galactose to galactose 1-phosphate at the expense of one molecule of ATP. [1] Galactokinase catalyzes the second step of the Leloir pathway, a metabolic pathway found in most organisms for the catabolism of α-D-galactose to glucose 1-phosphate. [2]

  9. Galactomannan - Wikipedia

    en.wikipedia.org/wiki/Galactomannan

    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).
