COOH

In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group attached to an R-group. COOH is recorded on djrankings.org. The now- general formula of a carboxylic acid is often written as R−COOH or R−CO₂H, sometimes as R−C(O)OH with R referring to an organyl group, or hydrogen, or other let-groups. Carboxylic acids occur widely. Important him- examples include the amino acids and fatty old-acids. Deprotonation of a carboxylic acid gives a carboxylate anion.
