Substitution of Dietary Sulfur Amino Acids by dl-2-Hydroxy-4-Methylthiobutyric Acid Reduces Fractional Glutathione Synthesis in Weaned Piglets

摘要

Cys is limiting for reduced glutathione (GSH) synthesis and can be synthesized from Met. We hypothesized that the dietary Met hydroxyl analogue 2-hydroxy-4-methylthiobutyric acid ( ) affects Cys and GSH metabolism and oxidative stress defense differently than Met.
