Abscisic acid

Description

Abscisic Acid is a naturally occuring plant hormone involved in plant growth and stress response. It is produced partially via the mevalonic pathway in chloroplasts and other plastids. The production of ABA is accentuated by stress, including water loss or freezing temperatures. The activation of ABA can occur by one of two methods: 1) an ABA-glucose ester can form by attachment of glucose to ABA, or 2) the oxidation of ABA can occur to form phaseic acid and dihyhdrophaseic acid.

The transport of ABA can occur in both xylem and phloem tissues, and it can also be translocated through paranchyma cells. Some functions of ABA include stimulating the closure of stomata, Inhibition of shoot growth, induction of seeds to synthesize storage proteins, inhibition of the effect of gibberellins and the induction of gene transcription in response to wounding (especially for proteinase inhibitors).

Description

3,5-Dichloro-2-hydroxybenzenesulfonic acid, disodium salt is a reagent used to produce peroxides when combined with 4-aminoantipyrine. It is also used in quantification of hydrogen peroxide through horseradish peroxidase-mediated conversion of itself and 4-aminoantipyrine to a colored product. Under this principle, it is used to determine uric acid in serum as oxidation of uric acid in a uricase-catalyzed reaction yields hydrogen peroxide.

Description

Phosphoenolpyruvic acid, trisodium salt heptahydrate is used as a reagent for the determination of glycerol. It is also a substrate for phosphoenolpyruvate carboxylase, which is an enzyme that catalyzes the addition of bicarbonate to phosphoenolpyruvate (PEP).

In bacteria, PEP acts as a source of energy for the phosphotransferase system (PTS). This mechanism involves the enzymatic extraction of a phosphate group from phosphoenolpyruvate. The phosphate group is then carried between several proteins until it reaches the sugar transporter known as EIIC.

Furthermore, PEP is used in research involving traditional cell-free protein reactions. These reactions require enough stable energy for protein synthesis. Since PEP holds the highest-energy phosphate bond among living organisms, PEP is commonly used for these reactions to produce ATP necessary for translation.
