Calcium tartrate
Calcium tartrate is also known as mn(iii) tartrate or tartaric acid, calcium salt, (r-r*,r*)-isomer. Calcium tartrate is soluble (in water) and a moderately acidic compound (based on its pKa). Calcium tartrate can be found in tamarind, which makes calcium tartrate a potential biomarker for the consumption of this food product. Calcium tartrate is a byproduct of the wine industry, prepared from wine fermentation dregs. It is the calcium salt of tartaric acid, an acid most commonly found in grapes. Its solubility decreases with lower temperature, which results in the forming of whitish (in red wine often reddish) crystalline clusters as it precipitates. It finds use as a food preservative and acidity regulator. Like tartaric acid, calcium tartrate has two asymmetric carbons, hence it has two chiral isomers and a non-chiral isomer (meso-form). Most calcium tartrate of biological origin is the chiral levorotatory (‚Äì) isomer . Calcium tartrate is also known as mn(iii) tartrate or tartaric acid, calcium salt, (r-r*,r*)-isomer.
