Orosomucoid (ORM) or alpha-1-acid glycoprotein (α 1 AGp, [1] AGP or AAG) is an acute phase protein found in plasma. It is an alpha-globulin glycoprotein and is modulated by two polymorphic genes. It is synthesized primarily in hepatocytes and has a normal plasma concentration between 0.6–1.2 mg/mL (1–3% plasma protein). [ 2 ]

The alpha-2 (α 2) adrenergic receptor (or adrenoceptor) is a G protein-coupled receptor (GPCR) associated with the G i heterotrimeric G-protein. It consists of three highly homologous subtypes, including α 2A-, α 2B-, and α 2C-adrenergic. Some species other than humans express a fourth α 2D-adrenergic receptor as well. [1]
In enzymology, a beta-galactoside alpha-2,3-sialyltransferase (EC 2.4.99.4) is an enzyme that catalyzes the chemical reaction CMP-N-acetylneuraminate + beta-D-galactosyl-1,3-N-acetyl-alpha-D-galactosaminyl-R ⇌ {\displaystyle \rightleftharpoons } CMP + alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,3-N-acetyl-alpha-D- galactosaminyl-R
In enzymology, a lactosylceramide alpha-2,3-sialyltransferase (EC 2.4.99.9) is an enzyme that catalyzes the chemical reaction CMP-N-acetylneuraminate + beta-D-galactosyl-1,4-beta-D-glucosylceramide ⇌ {\displaystyle \rightleftharpoons } CMP + alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,4-beta-D- glucosylceramide
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite .
The human alpha globin gene cluster is located on chromosome 16 and spans about 30 kb, including seven alpha like globin genes and pseudogenes: 5'- HBZ - HBZP1 - HBM - HBAP1 - HBA2 - HBA1 - HBQ1-3'. The HBA2 (α 2) and HBA1 (α 1) coding sequences are identical. These genes differ slightly over the 5' untranslated regions and the introns, but ...
There are 3 alpha-1 adrenergic receptor subtypes: alpha-1A, -1B and -1D, all of which signal through the Gq/11 family of G-proteins. Different subtypes show different patterns of activation. The majority of alpha-1 receptors are directed toward the function of epinephrine, a hormone that has to do with the fight-or-flight response.
