     Furthermore, wedelolactone also increased the activities of superoxidase dismutase (SOD) and glutathione peroxidase (GSH-Px) and decreased the level of the lipid peroxidation product malondialdehyde (MDA) in the liver, therefore decreasing the activity of alanine aminotransferase (ALT).

2. (countable) A specific residue, molecule, or isomer of this amino acid

   Two alanines are replaced by prolines.
