Descrizione generale

Poly(ethylene glycol) (PEG) is a linear polyether of ethylene glycol (ethane-1,2-diol). It is soluble in water, benzene, ethanol, acetonitrile, and dichloromethane. However, it is insoluble in diethyl ether and hexane. This non-ionic polymer can exist in the monomer and aqueous phases.

Applicazioni

Poly(ethylene glycol) has been used:

  • to grow the crystals of HLA-A∗02:01-N222-230 LLLDRLNQL (pHLA) complex
  • in the fabrication of ultrathin, free-standing, and porous polymer membranes for retinal tissue engineering
  • to grow the crystals of the C2c2-crRNA complex
  • to grow the crystals of the apo-C2c2 thermolysin-resistant core

Azioni biochim/fisiol

Poly(ethylene glycol) (PEG) is used in several pharmaceutical applications. This polymer occurs as a preservative and is used in biomedical applications like drug delivery systems, biosensing, and tissue engineering. PEG is also used in cosmetic ointments and creams. It is used as a binding and dispersing agent in chemical and other industries.
