What are liposomes？

Liposomes are tiny vesicles composed of a bilayer of phospholipids with a structure similar to a cell membrane. Phospholipid molecules have an amphiphilic property, hydrophilic at one end and lipophilic at the other, which enables liposomes to form a bilayer membrane structure that encapsulates and protects their internal contents, such as drugs and nutrients.

Main features of liposomes

High histocompatibility: Phospholipid bilayer structure similar to cell membrane, reducing immune rejection.
Low toxicity: composed of natural phospholipids, suitable for long-term use with few side effects.
Strong encapsulation ability: effectively encapsulates hydrophilic and lipophilic substances, such as drugs and proteins.
Controlled release: Regulate the release rate of active ingredients to achieve slow release or targeted delivery.

Hydrophilicity and lipophilicity

Hydrophilicity: The aqueous core of liposomes encapsulates hydrophilic nutrients, such as water-soluble vitamins and drugs, protecting them from destabilization in the digestive tract and facilitating their efficient transport to the small intestine.
Lipophilicity: The phospholipid bilayer of liposomes protects lipophilic substances, such as fat-soluble vitamins and drugs, from destruction in the digestive tract and facilitates their direct entry into cells and tissues through the liposome structure.
