Palmitoleic acid（Cat No.:R042729）is a monounsaturated omega-7 fatty acid with the chemical structure 16:1(n-7), meaning it has 16 carbon atoms and one double bond at the seventh position from the methyl end. Naturally found in macadamia oil, sea buckthorn oil, and human adipose tissue, it plays a role in metabolic regulation and cellular signaling. Palmitoleic acid has been studied for its anti-inflammatory, insulin-sensitizing, and lipid-lowering properties, making it of interest in cardiovascular and metabolic health research. It is also used in cosmetics for its moisturizing and skin-repairing benefits.
