The LDL-receptor (red) is a membrane protein found in almost every human cell. It binds to the apoprotein B100 from LDL-particles and mediates their internalization (endocytosis) in the cell. This occurs in almost all cells but mainly in the liver where it removes about 70 % of LDL from the circulation.
Chromosome structure with telomeres at the ends.
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
Inside protein molecule
Molecules of collagen serum and cream applied to skin and absorbed. 3D rendering.
A ribbons model of an antibody, also known as immunoglobin. The immune system produces antibodies (using white blood cells) which then identify and attack viruses and bacteria.
Host cells with spores (mold) are inside wood under the microscope for education.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
From left to right: the NMDA and  AMPA receptors transport calcium cations into neurons after being activated by the neurotransmitter glutamate and  the GABA receptor (right) transport chloride anions after the activation by gamma aminobutyrate. PDB entries: 6wht,  3kg2, 6d6u
