Amino-PEG-acid
Amino-PEG-acid compounds (also known as Acid-PEG-Amine compounds) are a class of bifunctional molecules featuring an amine (NH2) group on one end and a carboxylic acid (COOH) group on the other. The PEG (Polyethylene Glycol) chain between these functional groups provides flexibility, water solubility, and biocompatibility, making this class of compounds highly versatile in chemical, biological, and material science applications.
Key Features:
- Amine Group (NH2): Reacts with carboxyl groups and other electrophilic sites.
- Carboxylic Acid Group (COOH): Bonds with amine or hydroxyl groups via amide or ester formation.
- PEG Chain: Adds flexibility and improves solubility in water and organic solvents.
Key Applications:
- Bioconjugation: Amino-PEG-acid compounds effectively link biomolecules such as proteins, peptides, and drugs.
- Surface Modification: Used to functionalize surfaces like nanoparticles or polymers to enhance biological compatibility.
- Polymer Cross-Linking: Connects polymer chains for increased stability or to introduce specific functional groups.
This class of compounds plays a critical role in drug delivery systems, biomedical research, and material science due to their versatility and functional properties.
