General description

Palmitic acid, a long-chain saturated fatty acid, is frequently incorporated into biologic formulations, especially in the development of liposomes and other lipid-based delivery systems. In microbiology, it contributes to enhancing the solubility and stability of hydrophobic drugs, ensuring that biologic therapies retain their efficacy and are delivered effectively to the target site in the body.

The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.
