amino acid
No. A carboxyl group is made up off carbon, oxygen, and hydrogen.
The molecule with only a carboxyl group is called formic acid, with the formula HCOOH. It consists of a carboxyl group, COOH, where the hydrogen atom is attached to the carbon and the hydroxyl group (-OH) is attached to the same carbon.
ester
The carboxyl group is a functional group that consists of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group. In water, the hydrogen atom on the hydroxyl group can ionize and release a hydrogen ion (H+), making carboxyl groups acidic. Carboxyl groups are common in organic molecules found in living organisms.

An amino group and an R group
Chemical molecules.Amino acids have a two-carbon bond. One of the carbons is part of a group called the carboxyl group. A carboxyl group is made up of one carbon (C), two oxygens (O), and one hydrogen atom (H). The carboxyl group is acidic. The second carbon is a part of the amino group. Amino means there is an NH2 group bonded to the carbon atom.
In an amino acid, the central carbon atom is attached to an amino group, a carboxyl group, a hydrogen atom, and an R group (side chain). Therefore, the central carbon atom is not attached to a phosphate group in an amino acid.
This wording of this question sounds like you may be confused. In the term "carboxyl group", group refers to a specific group of atoms (COOH), not to a group of similar types of compounds. Since hydrocarbons by definition contain only carbon and hydrogen, a hydrocarbon cannot contain a carboxyl group.
The shape of acetic acid (CH3CO2H) is primarily determined by its molecular geometry, which includes a central carbon atom bonded to three hydrogen atoms and one carboxyl group (COOH). The carboxyl group exhibits a planar structure due to the double bond between carbon and oxygen, resulting in a trigonal planar arrangement around the carbon atom of the carboxyl group. Overall, the molecule can be considered as having a combination of tetrahedral geometry around the methyl group (CH3) and a planar structure around the carboxyl group.
A simple fat molecule is composed of one glycerol molecule, which is a simple sugar, and three fatty acid chains, which are chains of carbon and hydrogen with a carboxyl group at one end.
