CAS:D(+)-Lactic acid lithium salt is a dipolar molecule with an activation energy of about 44 kJ/mol. It has been studied by NMR techniques and found to have a resonance in the range of 1.8-2.0 ppm, which is characteristic of protons on the oxygen atom. The proton magnetic resonance (PMR) study showed that the d-lactate resonances were very broad and shifted to higher frequencies, whereas the l-lactate resonances were sharp and shifted to lower frequencies. This may be due to the different number of protons on each type of lactate molecule. The magnetic resonance (NMR) study showed that lithium salt was a radical with a spin density distribution around 2.6 ppm in the nmr spectrum.

Producto descatalogadoCalcium
CAS:Producto 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
