| alpha-amino acid | Typically, an amino acid of the general formula R-CHNH2-COOH (i.e., the NH2 in the a position); the l forms of these are the hydrolysis products of proteins. In rarer usages, this class of molecules also includes alpha-amino phosphoric acids and alpha-aminosulfonic acids. (05 Mar 2000) |
|---|---|
| alpha-amino acid esterase | <enzyme> Converts alpha-amino acid esters and water to alpha-amino acids and alcohol Registry number: EC 3.1.1.43 Synonym: alpha-amino acid ester hydrolase (26 Jun 1999) |
| alpha-aminoadipic acid | 2-amino-1,6-hexanedioic acid;an intermediate of lysine biosynthesis in higher fungi and bacteria, but not in algae and higher plants. Also in degradation of lysine in mammals. (05 Mar 2000) |
| alpha-amino-beta-ketoadipic acid | 2-Amino-3-oxo-1,6-hexanedioic acid;an intermediate of porphobilinogen synthesis formed by d-aminolevulinic acid synthase from succinyl-CoA and glycine; it rapidly decarboxylates to d-aminolevulinic acid. (05 Mar 2000) |
| alpha-aminoglutaric acid | <amino acid> One of the 20 _ amino acids commonly found in proteins. Plays a central role in amino acid metabolism, acting as precursor of glutamine, proline and arginine. Also acts as amino group donor in synthesis by transamination of alanine from pyruvate and aspartic acid from oxaloacetate. Glutamate is also a neurotransmitter, the product of its decarboxylation is the inhibitory neurotransmitter amino butyrate (GABA). (18 Nov 1997) |
| alpha-aminoisobutyric acid | 2-amino-2-methylpropionic acid;a synthetic amino acid useful in the study of amino acid transport across cell membranes and in the study of cytokine effects; it is not metabolised by the cell. (05 Mar 2000) |
| alpha-aminosuccinic acid | <amino acid> One of the twenty naturally occurring amino acids. Has the following chemical characteristics: pKa1 pKa2 pKa3 pI Water Solubility (30deg C)2.09-3.86 9.82 2.97 0.6 (09 Oct 1997) |
| alpha-hydroxymethyl-alpha'-(N-acetylaminomethylene)succinic acid hydrolase | <enzyme> Involved in degradation of vitamin b6; forms acetic acid plus ammonia plus carbon dioxide plus alpha-hydroxymethyl-succinic monoaldehyde Registry number: EC 3.5.1.- Synonym: compound b hydrolase (26 Jun 1999) |
| alpha-keto acid dehydrogenase | See: alpha-keto acid dehydrogenase.

(05 Mar 2000) |
| alpha-keto acid dehydrogenase complex | See: alpha-keto acid dehydrogenase. Anaerobic dehydrogenase, an enzyme (usually a pyridinoenzyme) catalyzing the transfer of hydrogen from some metabolite to some acceptor molecule (e.g., NAD+, cytochrome) other than oxygen; e.g., lactate dehydrogenase's, isocitrate dehydrogenase's, and others in EC class 1, excluding those listed under aerobic dehydrogenase. (05 Mar 2000) |
| alpha-ketoglutaramic acid | H2N-COCH2CH2COCOOH;a metabolite of glutamine formed by the action of glutamine aminotransferase; elevated in certain cases of hepatocoma. Synonym: 2-oxoglutaric acid. (05 Mar 2000) |
| alpha-ketosuccinamic acid | NH2-CO-CH2-CO-COOH;the transamination product of asparagine; acted upon by ω-amidase. (05 Mar 2000) |
| alpha-linolenic acid | <chemical> (z,z,z)-9,12,15-octadecatrienoic acid. A fatty acid that is found in plants and involved in the formation of prostaglandins. Chemical name: 9,12,15-Octadecatrienoic acid, (Z,Z,Z)- (12 Dec 1998) |
| alpha-(N-acetylaminomethylene)succinic acid hydrolase | <enzyme> Involved in degradation of vitamin b6; forms acetic acid plus ammonia plus carbon dioxide plus succinic monoaldehyde Registry number: EC 3.5.1.- Synonym: compound a hydrolase (26 Jun 1999) |

| lactic acid bacteria |
A large group of beneficial bacteria that have similar properties and all produce lactic acid as an end product of the fermentation process. They are widespread in nature and are also found in our digestive systems. Lactic acid bacteria have been used to ferment foods for at least 4000 years eg yoghurt, cheese... They may also be responsible for food spoilage.

| lactic acid |
Lactic acid builds up in the muscles as a byproduct of oxygen use and can cause cramping. Aerobic conditioning can prevent excessive lactic acid build up. Left wing lock: The left wing lock is a defensive strategy in which the left wing drops back to play parallel to the defense when the other team begins their breakout. Lift pass: A lift place clears the ice by a few inches on its way to another player. ...
