* Saturated vs. Unsaturated: In organic chemistry, "saturated" refers to a molecule where all carbon atoms have the maximum possible number of hydrogen atoms attached. "Unsaturated" means there are double or triple bonds between carbon atoms, allowing for potential addition of more hydrogen atoms.

* Tartaric Acid Structure: Tartaric acid has the chemical formula C₄H₆O₆. Each carbon atom in the molecule forms four single bonds, with no double or triple bonds. This means it is saturated.
