| beta | Entry pre fix is generally ignored for alphabetical reference, look for main portion of word. (18 Nov 1997) |
| beta (1)-anticollagenase | <chemical> A serum protein inhibitor (26 Jun 1999) |
| beta-(2-furyl)-acryloyl phosphate hydrolase | <enzyme> Used as synthetic substrate for atpase assay Registry number: EC 3.6.1.- Synonym: bfa phosphatase (26 Jun 1999) |
| beta 2-microglobulin | An 11 kD protein associated with the outer membrane of many cells including lymphocytes. It is the small subunit of the MHC class I molecule. Association with beta 2-microglobulin is generally required for the transport of class I heavy chains from the endoplasmic reticulum to the cell surface. Beta 2-microglobulin is present in small amounts in serum, csf, and urine of normal people, and to a much greater degree in the urine and plasma of patients with tubular proteinaemia, renal failure, or kidney transplants.

| beta-adrenergic blocking agent | A class of drugs that compete with beta-adrenergic agonists for available receptor sites; some compete for both b1 and b2 receptors (e.g., propranolol) while others are primarily either b1 (e.g., metoprolol) or b2 blockers; used in the treatment of a variety of cardiovascular diseases where beta-adrenergic blockade is desirable. Synonym: beta-adrenergic receptor blocking agent, beta-adrenoreceptor antagonist, beta-blocker. (05 Mar 2000) |

| beta-adrenergic receptor kinase | <enzyme> Cyclic-AMP protein kinase which specifically phosphorylates the agonist-occupied form of beta-adrenergic receptor Registry number: EC 2.7.1.- Synonym: beta-ar kinase, beta-adrenergic receptor kinase 1, g-protein-coupled receptor kinase 2, grk2 (kinase), beta-adrenergic receptor kinase 2, beta-ar kinase 2 (26 Jun 1999) |
| beta-adrenergic receptors | Adrenergic receptor's in effector tissues capable of selective activation and blockade by drugs; conceptually derived from the ability of certain agents, such as propranolol, to block only some adrenergic receptor's and of other agents, such as isoproterenol, to activate only the same adrenergic receptor's. Such receptor's are designated as beta-receptors. Their activation results in physiological responses such as increases in cardiac rate and force of contraction (b1), and relaxation of bronchial and vascular smooth muscle (b2). (05 Mar 2000) |
| beta-adrenoreceptor antagonist | A class of drugs that compete with beta-adrenergic agonists for available receptor sites; some compete for both b1 and b2 receptors (e.g., propranolol) while others are primarily either b1 (e.g., metoprolol) or b2 blockers; used in the treatment of a variety of cardiovascular diseases where beta-adrenergic blockade is desirable. Synonym: beta-adrenergic receptor blocking agent, beta-adrenoreceptor antagonist, beta-blocker. (05 Mar 2000) |
| beta-alanine | <chemical> Beta-alanine. An amino acid formed in vivo by the degradation of dihydrouracil and carnosine. Since neuronal uptake and neuronal receptor sensitivity to beta-alanine have been demonstrated, the compound may be a false transmitter replacing gaba. A rare genetic disorder, hyper-beta-alaninaemia, has been reported. Chemical name: beta-Alanine (12 Dec 1998) |
| beta-alanine-pyruvate aminotransferase | <enzyme> An enzyme that reversibly transfers the amino group of beta-alanine to paruvate, thus producing l-alanine and malonate saemialdehyde. A deficiency of this enzyme is believed to be the cause of hyper-beta-alaninaemia. (05 Mar 2000) |
| beta-alanyl-arginine hydrolase | <enzyme> Also hydrolyzes carnosine, at a lower rate; requires mn2+; inhibited by bestatin; stabilised by sulfhydryl reagents Registry number: EC 3.4.13.- Synonym: ala-arg hydrolase (26 Jun 1999) |
| beta alcoholism | Jellinek's term for the physical complaints associated with excessive use of alcohol, such as polyneuropathy, gastritis, and liver cirrhosis. (05 Mar 2000) |
