WebSince our cell membrane has a very large hydrophobic region, it prefers nonpolar molecules. And since these phospholipids are packed so closely together, our cell membrane also prefer small molecules to pass through. So our cell membrane is semi-permeable, allowing, generally, small and nonpolar molecules to pass through the cell membrane. WebAug 18, 2024 · Although some components of the cell membrane are different, one of the most uniformly important and conserved components of a cell membrane is an important molecule that has a dual...

WebApr 11, 2024 · The biological membrane is one of the basic structures of the cell. It consists of a phospholipid bilayer that acts as a physical barrier to separate distinct intracellular compartments (such as the endoplasmic reticulum (ER), Golgi apparatus, and nucleus), and separates the cell from the external environment [ 1 ]. WebThe efficiency of tumor cell targeting of fluorescent prodrugs remains unsatisfactory, especially for small-molecule drugs in the human body. To address this challenge, the large-scale screening of cell-specific receptors, targets, or inhibitors that can be efficiently targeted by fluorescent prodrugs is of particular promise for precision ...
