What is the monomer of a protein? could you possibly give me an example?

Thanks!

What is an amino acid? Answer...a monomer of a protein.

The monomer of a protein is called an amino acid. An amino acid is a small molecule that contains an amine group (-NH2) and a carboxylic acid group (-COOH) connected to the same carbon atom, called the alpha carbon. There are 20 different amino acids commonly found in proteins, each characterized by a unique side chain, also known as the R-group.

To provide an example, let's consider the amino acid called glycine. Glycine is the simplest amino acid and its side chain consists of just a single hydrogen atom. Its chemical structure is H2N-CH2-COOH. Glycine, along with other amino acids, serves as a building block for proteins. By joining several amino acids together through peptide bonds, proteins are formed.
