What is the definition of “amino acid” according to MPEP 2412.03(b)?

According to MPEP 2412.03(b), the definition of “amino acid” is broad and inclusive. The section states:

“‘Amino acid’ includes any D- or L-amino acid or modified amino acid as defined in paragraph 3(a) of WIPO Standard ST.26.”

This definition encompasses not only standard L-amino acids but also D-amino acids and modified amino acids with synthetic side chains. It’s important to note that peptide nucleic acid (PNA) residues are considered nucleotides, not amino acids.
