Description

2-Deoxy-D-galactose is a deoxy hexose that inhibits synthesis of glycoproteins in Influenza virus, such as hemagglutinin and neuraminidase, by blocking glycosylation. 2-Deoxy-D-galactose also inhibits the glycosylation of mammalian proteins involved in neurotransmitter release and synaptogenesis in the hippocampus. It has been used for isolating galactose permease mutants of Salmonella typhimurium and in the inhibition of glycolysis in Saccharomyces cerevisiae. It has also been used to isolate and elucidate the activity of a system for galactose uptake into E. coli.

2-keto-D-gluconic acid is found in the carrageenan polysaccharide of Irish moss and can be used as a stabilizer in the storage of biological materials. 2-keto-D-gluconic acid exhibits antimicrobial properties against species of Pseudomonas that cause plant disease. Genes for metabolism of 2-keto-d-gluconic acid are controlled by the UxuR regulon in E. coli. 2-keto-D-gluconic acid is converted to D-mannonate by the enzyme fructuronate reductase (EC 1.1.1.57). 2-keto-D-gluconic acid hemicalcium salt can be used to make D-erythorbic acid using an α-amylase enzyme. It can also be used to prepare D-ribulose and D-arabinose by heating in pyridine with a nickel acetate catalyst.

A-082-25 25 g $ 76.00

Description

Adenosine-5'-monophosphate (AMP) plays an important role in cellular metabolic processes as it is a precursor to adenosine-5'-triphosphate (ATP).

The phosphate in AMP can be correlated with ATP and ADP. AMP contains only one phosphate group attached at the 5’ position, whereas ATP consists of three phosphate groups attached in series to the 5’carbon location, and ADP contains two phosphate groups attached to the 5’ position. AMP can also have an activating effect on a class of protein kinases known as AMP-activated protein kinases, or AMPKs.

Description

Adenosine-5'-triphosphate (ATP) is an important molecule in vivo for energy storage and metabolism and is often called the "molecular unit of currency" of intracellular energy transfer. ATP is a coenzyme in multiple reactions as well as a substrate for multiple kinases where it helps to propagate a signal either inside or outside of the cell.

The three phosphates in ATP can be correlated with ADP and AMP. ATP consists of three phosphate groups attached in series to the 5’carbon location, whereas ADP contains two phosphate groups attached to the 5’ position, and AMP contains only one phosphate group attached at the 5’ position.

Adonitol, also known as ribitol, is the reduced alcohol form of ribose. Adonitol is found in plants of the genus Adonis, from which the molecule takes its name. It is a component of teichoic acids found in the cell walls of Gram positive bacteria. Adonitol is also a moiety present in riboflavin (vitamin B2). Adonitol is commonly used in media for cryopreservation and lyophilization of cells. It is metabolized by some microbes, but not others so an adonitol fermentation test can be used to help identify an unknown microbial organism.

Description

Idebenone is a synthetic analog of ubiquinone (CoQ10). It scavenges free radicals and acts as an antioxidant. Idebenone differs from ubiquinone by having a shorter, less lipophilic tail and thus can function in multiple cellular environments. In contrast to ubiquinone, idebenone acts as a competitive inhibitor of complex I in the electron transport chain and is capable of facilitating cellular respiration that is independent of a functioning complex I. It can accept electrons from the glycerophosphate shuttle, NADH-quinone oxidoreductase, and complex II of the electron transport chain. Idebenone was originally developed to treat cognitive disorders such as Alzheimer’s disease, but was not found to be effective so other uses are being explored.

Description

L-Arabinose is an arabinose isomer widely found in nature, while D-arabinose is less common. L-Arabinose is a constituent of many biopolymers that make up plant cell walls.

This monosaccharide is often used in cell culture media, serving as a bacterial carbon source, and can be used to distinguish between bacteria based on their fermentation abilities.

L-Arabinose, in the absence of glucose, induces transcription of the ara operon in E. coli that encodes L-arabinose catabolizing enzymes. It does this by binding to the AraC protein and activating the PBAD promoter. The PBAD promoter is used in plasmid vectors as a switch for protein expression that can be turned on by L-arabinose or turned off by addition of glucose.
