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.

Description

Homocysteine is a cysteine homolog,and only differs by having an additional methylene bridge. It is often used in vitro as a reference to measure L-homocysteine in plasma in order to diagnose homocystinuria. This genetic disorder causes the body to be unable to process certain amino acids.

Higher levels of homocysteine found in the body is due to having vitamin B6 or B12 deficiencies. Finding higher levels may indicate possible cardiovascular disease; however, reducing the levels of homocysteine in the body does not appear to remedy the situation.

Description

Tryptophan is an essential amino acid in the human diet. Its functions as a serotonin precursor have increased interest in its ability to treat depression and epilepsy; however, there has been inconclusive evidence in clinical trials regarding its efficacy in humans. Safety has also been a concern.

It is widely used in molecular genetics as an auxotrophic genetic marker in yeast gene disruption experiments.

Description

Nalidixic acid is a naphthyridone antibiotic that is similar in structure and mechanism to quinolones and is effective against both gram-positive and gram-negative bacteria. It acts as a bacteriostatic in lower concentrations but can be bacteriocidal at higher concentrations. Nalidixic acid indirectly inhibits proteins synthesis by binding DNA and interfering with enzymes involved in DNA replication and transcription and is commonly used in the treatment of urinary tract infections.

S-117-500 500 g $ 66.00

Description

Pyruvic acid is the simplest alpha-keto acid, and is considered to be key in several metabolic processes. Because pyruvate, which is the carboxylate ion of pyruvic acid, can be converted into carbohydrates, fatty acids or energy, it is a uniting intermediate compound and its fate depends on the organism and environment.

It is produced during glycolysis, and through the Krebs cycle (citric acid cycle), it supplies cells with energy. Two molecules of pyruvate are produced from one glucose molecule. Pyruvate is then converted into acetyl-coenzyme A used in the Krebs cycle.

In gluconeogenesis, pyruvic acid can be converted back into glucose or glycogen, and in environments with low oxygen, pyruvic acid is broken down anaerobically into lactic acid.

Clinically, the lactate-to-pyruvate ratio can assist in diagnosing mitochondrial respiratory chain disorders because the ratio is often, but not always elevated in these cases. There is also a lower ratio typically observed in inherited pyruvate metabolic disorders.
