1. Stearic acid (Cetylacetic acid) can reduce metastatic tumor burden. 2. Stearic acid leads to dramatically reduced visceral fat likely by causing the apoptosis of preadipocytes. 3. Stearic acid and its derivatives have been used as gelators in food and pharmaceutical gel formulations. 4. Stearic acid is a potent phosphatase 1B inhibitor, possibly causing an enhancement in the insulin receptor signaling to stimulate glucose uptake into adipocytes. 5. Stearic acid has the potential to increase dry matter intake and yields of milk and milk components, without affecting conversion of feed to milk, body condition score, or body weight.
