an organic acid containing a carboxyl group; the general formula is RCOOH.
an organic acid characterized by one or more carboxyl groups
one of the sticky ends on an amino acid.
A substance containing the carboxyl group. The carboxylic hydrogen can be lost as a hydrogen ion, so these substances are also acidic. An example includes acetic acid.
an organic compound containing the carboxyl group.
Simply, a compound present in living organisms or organic, non-living substances that contains one or more carboxyl groups (COOH).
carboxyl; carboxyl group. A carboxylic acid is an organic molecule with a -(C=O)-OH group. The group is also written as -COOH and is called a carboxyl group. The hydrogen on the -COOH group ionizes in water; carboxylic acids are weak acids. The simplest carboxylic acids are formic acid (H-COOH) and acetic acid (CH3-COOH).
Acids containing a carboxyl group, COOH.
Carboxylic acids are organic acids characterized by the presence of a carboxyl group, which has the formula -C(=O)OH, usually written -COOH or -CO2H.
