Sorbic acid-13C2 is the 13C-labeled Sorbic acid (HY-N0626). Sorbic acid is an effective, safe, and non-toxic food preservative. It can effectively inhibit most molds, yeasts, and certain bacteria. Sorbic acid is orally active and can enhance the growth performance of economically important animals (Duroc * Landrace * Yorkshire piglets) by activating the insulin-like growth factor system (IGF), and it can also lead to lipid accumulation by disrupting lipid clearance pathways[1][2][3][4].
