Fonctionnalisation of calcium-zinc hydroxyapatite by tartaric acid

Inhibition of growth of urinary type calcium hydrogen phosphate dihydrate crystals by tartaric acid and tamarind

Urinary stone is one of the oldest and the most common afflictions in humans, animals and birds. A number of people suffer from urinary stones. Brushite or calcium hydrogen phosphate dihydrate (CHPD) crystals are frequently found in urinary stones. Many fruits contain high amount of tartaric acid. Therefore, the effect of tartaric acid on the growth of CHPD crystals is presented in this article...

Nucleation and Growth of Tin-Zinc Electrodeposits on a Polycrystalline Platinum Electrode in Tartaric Acid

Medidas de transientes de corrente e microscopia eletrônica de varredura foram utilizados para caracterizar o processo de eletrocristalização e morfologia de ligas de estanho-zinco eletrodepositadas sobre Pt, na ausência e na presença de ácido tartárico. O modelo de Scharifker e Hills foi utilizado para analisar os transientes de corrente e revelou que o processo de eletrocristalização da liga ...

Glycochenodeoxycholic acid inhibits calcium phosphate precipitation in vitro by preventing the transformation of amorphous calcium phosphate to calcium hydroxyapatite.

Calcium hydroxyapatite can be a significant component of black pigment gallstones. Diverse molecules that bind calcium phosphate inhibit hydroxyapatite precipitation. Because glycine-conjugated bile acids, but not their taurine counterparts, bind calcium phosphate, we studied whether glycochenodeoxycholic acid inhibits calcium hydroxyapatite formation. Glycochenodeoxycholic acid (2 mM) totally ...

Diastereoselective encapsulation of tartaric acid by a helical aromatic oligoamide.

A helical aromatic oligoamide foldamer encapsulates tartaric acid with exceptional affinity, selectivity, and diastereoselectivity. The structure of the complex has been elucidated both in solution by NMR spectroscopy and in the solid state by X-ray crystallography, making it possible to rationalize the strong effects observed, particularly the role of hydrogen bonds between the hydroxyl and ca...
