    Biochem/physiol Actions

    N-Acetyl-D-penicillamine (NAP or NAPA), a thiol compound, is often used as a control molecule in studies involving nitric oxide donor molecules such as S-nitroso-N-acetyl-dl-penicillamine (SNAP) and sodium nitroprusside (SNP). N-acetyl-D-penicillamine (NAPA) is also used as a heavy metal chelator.
