The old cliché about finding rare and valuable coins is that you should start by digging around in your sofa. That's not necessarily bad advice. However, chances are the only loose change you'll ...
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 GGTA1 gene.
The front of a U.S. Marine Corps birthday ball medallion Huguenot méreau used as a challenge coin during 17th century Protestant persecution in France. A challenge coin is a small coin or medallion, bearing an organization's insignia or emblem and carried by the organization's members. Traditionally, they might be given to prove membership ...
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.
A challenge coin, tucked in the palm of the United States president, is passed to a member of the military in a seemingly ordinary handshake. ... ranging in price from $3.50 to $21.95.
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

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]
