Produto descontinuadoDL-Lactic acid sodium salt, 60% w/w syrup
CAS:Lactic acid is a natural product that has been used for many years as an antimicrobial agent in wastewater treatment. It is also used in the food industry to prevent the growth of bacteria and fungi, and as a preservative. Lactic acid has been shown to have a physiological effect on locomotor activity, which may be due to its ability to convert pyruvate into lactate. Lactic acid also inhibits the growth of some bacterial strains by increasing the disulfide bond formation between two cysteine residues. The sodium salt form of lactic acid is more soluble than the acid form and can be used as an experimental model for studying sodium-lactate interactions. Sodium lactate is used in maternal blood transfusions to increase blood pH levels during labor, and is also added to water vapor for humidification purposes.

CAS:Sodium metabisulfite is a preservative used to inhibit microbial growth in food and drinks. This chemical has been shown to cause bronchoconstriction in animals, but the mechanism for this effect is not well understood. Sodium metabisulfite may also cause anaphylactic reactions in humans. There are no toxicity studies available for sodium metabisulfite injection solutions, but it has been shown that anhydrous sodium metabisulfite can be toxic at high doses. The effects of sodium metabisulfite on human cells have been studied using a surface methodology and cytotoxicity assay. These experiments showed that sodium metabisulfite significantly reduced cellular viability and had significant cytotoxic effects on cells. The mechanism of this cell death was found to be due to the enzyme activity of sulfite oxidase, which produces hydrogen peroxide as a by-product. This hydrogen peroxide causes oxidative stress and leads to the production of reactive oxygen species (ROS) that induce DNA damage

CAS:Produto ControladoCalcium is a chemical element with the symbol Ca and atomic number 20. It has an atomic weight of 40.078, which means that it is 40.078 times heavier than hydrogen. Calcium is an alkaline earth metal, as are magnesium and barium. Calcium is classified as a hard metal because it has a high melting point and its oxide layer resists corrosion by water and air. The ionized form of calcium (Ca2+) may be found in the cytosol, or in transport vesicles in muscle cells or other types of cells such as those of the intestine or bone cells. The main biological role of calcium ions is to maintain the potential difference across excitable cell membranes, enabling normal nerve transmission and muscle contraction, including the contraction of heart muscles. The concentration of calcium ions in extracellular fluid is tightly regulated by the kidneys under instruction from parathyroid hormone (PTH) and calcitonin hormones to keep blood calcium levels within a narrow range

CAS:Sodium linoleate is a model system for studying the effect of radiation on tumorigenesis. Sodium linoleate is used to study the relationship between light exposure and cancer. It has been shown to inhibit Cox-2 expression in carcinoma cell lines, which may be due to its ability to inhibit cox-2 activity by preventing the production of prostaglandins E2 (PGE2). The increased levels of PGE2 can lead to an increase in inflammation and cancer growth. Sodium linoleate has also been shown to have a synergic effect with sodium carbonate in inhibiting tumour growth, which is due to the inhibition of nuclear DNA transcription and protein synthesis.
