Tartronic acid, a dicarboxylic acid derive, is an inhibitor of the transformation of carbohydrates into fat under fat-deficient diet conditions. Tartronic acid promotes 3T3-L1 adipocyte differentiation by increasing the protein expression of FABP-4, PPARgamma and SREBP-1. Tartronic acid promotes de novo lipogenesis and inhibits CPT-1beta by upregulating acetyl-CoA and malonyl-CoA. Tartronic acid promotes weight gain and induces adipocyte hypertrophy in epididymal white adipose tissue and lipid accumulation in the livers of high-fat diet induced obese mice. Tartronic acid can be used for lipid metabolic disease research[1].
