Carboxylic acids {carbonic acid} can have one carbon, three oxygens, and two hydrogens.
Carboxylic acids {dicarboxylic acid} can have carboxyl groups on both ends. Small dicarboxylic acids have two carbons {oxalic acid}, three carbons {malonic acid}, four carbons {succinic acid}, five carbons {glutaric acid}, or six carbons {adipic acid}.
Propanoic acid {lactic acid} can have hydroxyl group on second carbon.
Organic molecules {limonene} can be skin irritants.
Benzene rings {phthalic acid} can have adjacent carboxyl group. Phthalates can affect body hormone levels.
Propanoic acid {pyruvic acid} can have ketone on second carbon.
Benzoic acid {salicylic acid} can have a hydroxyl group in para- position.
large dicarboxylic acid {tartaric acid} {cream of tartar, acid}.
Branched carbon chain can have three carboxyl groups {tricarboxylic acid}, such as citric acid.
