A functional group that is acidic and part of the amino acid backbone: ____________

The amino acid backbone is common/ primary to all amino acids and the R-group is what makes each amino acid unique. The alpha-carbon is central and is connected to the amino group (NH3+), Carboxylic acid group (COOH), Hydrogen (H) which form the backbone and the R-group which differs in each amino acid.

A carboxylic group is a functional group that is acidic and part of the amino acid backbone.

An amino acid residue consists of an amine group (-NH2), a carboxylic acid group (COOH), a hydrogen atom (H), and a variable group as a side chain (-R).

A carboxylic acid (COOH) group is a functional group in which a carbon (C) atom is double-bonded with an oxygen (O) atom and single bonded with a hydroxy (OH) group.

In an amino acid, both NH2 and COOH groups are linked to the same carbon (C) atom.

In conclusion, a carboxylic group is a functional group that is acidic and part of the amino acid backbone.
