Effect of carboxymethyl chito-oligosaccharide on cysteine absorption in intestinal porcine epithelial cells
Oxidative stress is associated with retarded growth and the initiation and progression of diseases in pigs.The carboxymethylation of chito-oligosaccharide (COS) can improve its antioxidant activity for such SANDALWOOD issues.Herein, an orthogonal experiment L9 (34) test design was used to optimise the preparation conditions of carboxymethyl (CM)-CO
