| Adenosylhomocysteinease from Human, Recombinant | S-adenosylhomocysteine hydrolase belongs to the adenosylhomocysteinase family. It catalyzes the reversible hydrolysis of S-adenosylhomocysteine (AdoHcy) to adenosine (Ado) and L-homocysteine (Hcy). Thus, it regulates the intracellular S-adenosylhomocysteine (SAH) concentration thought to be important for transmethylation reactions. Deficiency in this protein is one of the different causes of hypermethioninemia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. Adenosylhomocysteinase is an enzyme that converts S-adenosylhomocysteine to homocysteine and adenosine. This enzyme catalyses the following chemical reaction: S-adenosyl-L-homocysteine + H2O<-> L-homocysteine + adenosine. The enzyme contains one tightly bound NAD+ per subunit. Group: Enzymes. Synonyms: Adenosylhomocysteinase; S-adenosylhomocysteine synthase; S-adenosylhomocysteine hydrolase; adenosylhomocysteine hydr. Enzyme Commission Number: EC 3.3.1.1. CAS No. 9025-54-1. AHCY.

| Hypaconitine | Hypaconitine is a cytosolic Ca2+ antagonist that can be used to study the mechanism of cardiac arrhythmias. Hypaconitine binds to the sarcoplasmic reticulum and blocks the release of Ca2+, which increases the concentration of intracellular Ca2+. This increase in intracellular Ca2+ inhibits cardiac contractility, leading to cardiac arrest. Hypaconitine has also been shown to inhibit growth factor-β1 (GF-β1). It has a chemical structure similar to aconitine, which is a toxic compound found in plants such as monkshood. Aconitine inhibits mitochondrial function by binding to polymerase chain reaction (PCR) DNA polymerase and blocking DNA synthesis. Hypaconitine also binds to PCR DNA polymerase and inhibits DNA synthesis, but does not inhibit mitochondrial function. Group: Other alkaloids.

| L+Lactic Acid, Calcium Salt, Pentahydrate | Lactic acid (2-hydroxypropanoic acid), also known as milk acid, is a chemical compound that plays a role in several biochemical processes. It was first isolated in 1780 by a Swedish chemist, Carl Wilhelm Scheele, and is a carboxylic acid with a chemical formula of C3H6O3. It has a hydroxyl group adjacent to the carboxyl group, making it an alpha hydroxy acid (AHA). In solution, it can lose a proton from the acidic group, producing the lactate ion CH3CH(OH)COO?. It is miscible with water or ethanol, and is hygroscopic. Lactic acid is chiral and has two optical isomers. One is known as L-(+)-lactic acid or (S)-lactic acid and the other, its mirror image, is D-(-)-lactic ac...or Hartmann's Solution in the UK). This intravenous fluid consists of sodium and potassium cations, with lactate and chloride anions, in solution with distilled water in concentration so as to be isotonic compared to human blood. It is most commonly used for fluid resuscitation after blood loss due to trauma, surgery, or a burn injury. Group: Biochemicals.

| Methamphetamine (BSA) | Methamphetamine (METH) is closely related chemically to amphetamine (AMPH). METH is a potent central nervous system stimulant with additional peripheral sympathomimetic effects. METH and AMPH have been used clinically in the treatment of obesity, minimal brain dysfunction, narcolepsy, depression and to counter fatigue. They are also subjected to widespread abuse. METH is an indirect agonists. It causes the release of newly synthesized norepinephrine and dopamine and it blocks the re uptake of these transmitters from the synapse. This can lead to an increase in the concentration of catecholamines in the synapse as well as an overall increase in catecholaminergic activity in the brain. The mechanism of METH induced neurotoxicity for all monoaminergic cell types may lie primarily with the dopaminergic system in the striatum. It may also lie with the interaction between METH induced release of dopamine and its ability to inhibit monoamine oxidase. Group: Biochemicals. Grades: Highly Purified. Pack Sizes: 1mg.
