Cat.No.S3794

Palmitic acid (Hexadecanoic acid, Cetylic acid) is the most common saturated fatty acid found in animals, plants and microorganisms with anti-tumor activity. This compound is a fatty acid that is almost insoluble in water-soluble solvents such as culture medium. It needs to be emulsified before use in cell experiments. It is recommended to purchase it in powder form.

Mechanism of Action

In vitro	Palmitic acid (PA) binds TLR4 via the adaptor protein MD2 and that the TLR4 signal induced by this compound stimulates dendritic cells activation and maturation accompanied by a robust IL-1β response. It is a TLR4/MD-2 ligand. This chemical exerts pro-inflammatory activity through TLR4.
In vivo	In a dose-dependent fashion, palmitic acid rapidly reduces mouse locomotor activity by a mechanism that did not rely on TLR4, MyD88, IL-1, IL-6 or TNFα but is dependent on fatty acid chain length. This compound induces anxiety-like behavior in mice while increasing amygdala-based serotonin metabolism.
