Citric acid - Wikipedia

Synthesize solid materials from small molecules. In materials science, the Citrate-gel method is a process similar to the sol-gel method, which is a method for producing solid materials from small molecules. During the synthetic process, metal salts or alkoxides are introduced into a citric acid solution.

US Patent for Metal amino acid chelate Patent …

A water soluble metal amino acid chelate is prepared by adding a metal salt to deaerated water, mixing the salt solution with a mixture of an amino acid and an organic acid and adjusting the pH of the resulting composition to a range of from about 4.5 to about 8.5 to produce a clear solution. The resultant clear solution can then be applied to plants or it can be dried for storage.

Infrared Spectra and Characteristic Frequencies of

In a crystal composed solely of monatomic ions, such as sodium chloride, potassium bromide, and calcium fluoride, the only vibrations are “lattice” vibrations, in which the individual ions undergo translatory oscillations. The resulting spectral bands are broad and are responsible for the long wave-length cutoff in transmission.

Calcium in biology - Wikipedia

Calcium ions (Ca 2+) contribute to the physiology and biochemistry of organisms cell.They play an important role in signal transduction pathways, where they act as a second messenger, in neurotransmitter release from neurons, in contraction of all muscle cell types, and in fertilization.Many enzymes require calcium ions as a cofactor, including several of the coagulation factors.

Secondary transporters of citrate in complex with metal ions belong to the bacterial CitMHS family, about which little is known. The transport of metal-citrate complexes in Streptomyces coelicolor has been investigated. The best cofactor for citrate uptake in Streptomyces coelicolor is Fe 3+, but uptake was also noted for Ca 2+, Pb 2+, Ba 2+, and Mn 2+.
