Description
α-D-Fucose is a six-carbon deoxy monosaccharide. It is equivalent to 6-deoxy-D-galactose. D-fucose acts as a non-metabolizable analogue of L-arabinose and inhibits induction of the L-arabinose operon in some bacteria. Some resistant bacteria possess a mutant araC gene where D-fucose acts as a gratuitous inducer of the L-arabinose operon. D-fucose induces β-galactosidase to some extent in Lactobacillus plantarum. α-D-fucose inhibits the eukaryotic enzyme Lysine-specific demethylase 1 (LSD1A), thereby causing gene repression. α-D-fucose is being explored in treatments for neurodegenerative diseases because of its effect on gene repression. Seen upregulated in many cancers, LSD1A overexpression pushes the cell cycle of otherwise non-transformed View product page →

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.

Description
2-Deoxy-D-ribose is a reducing sugar that is incorporated into deoxyribonucleic acid (DNA). It is a degradation product of thymidine generated by thymidine phosphorylase. 2-Deoxy-D-ribose inhibits apoptosis induced by hypoxia by suppressing hypoxia-inducible factor 1a. It also promotes angiogenesis and the chemotactic activity of endothelial cells. Thus, inhibition of 2-Deoxy-D-ribose is being explored in anti-cancer treatments. 2-Deoxy-D-ribose also induces apoptosis in human fibroblasts by depleting intracellular levels of reduced glutathione and causing oxidative stress while disturbing the cytoskeletal structure.

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. Product Specifications 2-Keto-D-gluconic View product page →

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.Product Specifications Adenosine-5'-monophosphate, Disodium hexahydrate, Ultra Pure AMPFormula: C10H12N5O7PNa2 ∙ 6 H2OMW: 499.19 g/mol Storage/Handling: Store at - View product page →

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
Chenodeoxycholic acid is one of the primary bile acids produced by humans. Bile acids or bile salts are intestinal, natural detergents; their main function is to solubilize lipids in the digestive processes. The major action of a bile salt, such as chenodeoxycholic acid, is to form micelles in order to emulsify fats and oils. Chenodeoxycholic acid also acts as a hormone-like ligand for the nuclear farnesoid X receptor which regulates transcription of many genes. Bile acids are used in bacteriological culture media as a selective inhibitory agent. Most aerobic enteric bacteria are resistant to the inhibitory effects of chenodeoxycholic acid.
