Monomeric Proteins
A monomeric protein is a single protein molecule. The monomers are the individual protein molecules that make up the polymeric proteins.
The Monomers of Protein Bonds
The monomers of protein bonds are amino acids. These are organic compounds that contain a carboxyl group (COOH), an amino group (NH2), a hydrogen atom, and a variable side chain. The side chain determines the particular amino acid. There are 20 different amino acids in humans.
Proteins
are made up of amino acids. The sequence of amino acids in a protein is determined by the sequence of codons in the gene that codes for that protein.
A gene is a section of DNA that codes for a specific protein. The sequence of codons in a gene is determined by the sequence of nucleotides in the DNA molecule. Each codon is a three-nucleotide sequence that codes for a specific amino acid.
The sequence of amino acids in a protein is determined by the sequence of codons in the gene that codes for that protein.
Building Blocks Monomers of Proteins
A protein is a molecule composed of amino acids. The sequence of amino acids in a protein is its primary structure. Proteins are built from monomers called amino acids. There are 20 standard amino acids, and the sequence of amino acids in a protein determines its secondary and tertiary structure, as well as its function.
