Tartiedostomuodot
Tartiedostomuodot refers to the various forms that tartaric acid can take. Tartaric acid, or 2,3-dihydroxybutanedioic acid, is a dicarboxylic acid that exists in several stereoisomeric forms due to its chiral centers. The most common and naturally occurring form is L-(+)-tartaric acid, found in grapes and other fruits. This form is optically active, rotating plane-polarized light to the right.
Another isomer is D-(-)-tartaric acid, which is the enantiomer of L-(+)-tartaric acid. It rotates plane-polarized light
Finally, there is racemic tartaric acid, also known as DL-tartaric acid. This is a mixture of equal
