How do hydrophobic molecules enter a cell
WebMethods for removing contaminants from aqueous media using polyelectrolyte complexes having a heterogeneous charge distribution are provided. The polyelectrolyte complexes are formed from an amphiphilic anionic random copolymer and a cationic random copolymer are provided. The polyelectrolyte complexes absorb cationic, anionic, or hydrophobic … WebGlycoproteins and Glycolipids are proteins and lipids, with various carbohydrate molecules attached to them. The carbohydrate groups project out of the cell, and one of their main functions is to act as receptor molecules for certain substances such as hormones. Detergents are made of a long hydrophobic side chain and a charged polar head.
