英语释义

1. any of a series of polymers H(OCH2CH2)nOH where n is greater than three that vary from viscous liquids to waxy solids and are used especially as lubricants and in medical and biotechnological applications —abbreviation PEG

2. any of a series of polymers H(OCH2CH2)nOH where n is greater than three that vary from viscous liquids to white solids and are used in medicine especially as laxatives and as bases for pharmaceutical ointments and cosmetic creams —abbreviation PEG Note: The covalent attachment of polyethylene glycol chains to biomolecules ((see pegylation)) is used especially to improve the bioavailability, solubility, and stability of therapeutic agents and to reduce their immunogenicity.
