How would a protein that resides in the nonpolar interior of a membrane fold compared with the water-soluble protein just discussed?
Glycolids are nonionic lipids that can orient themselves into bilayers in a manner similar to the phospholipids. Suggest a reason why they can accomplish this feat despite their lack of ionic group similar to that found in phospholipids
The terms nonpolar and polar as well as hydrophilic andhydrophobic can also be used to describe molecules. Howare these terms related to lipid-soluble and non-lipid-soluble?
