Isolated cholesterol molecule between phospholipid molecules membrane 3d rendering
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.
A carboxypeptidase is a protease enzyme that hydrolyzes a peptide bond at the carboxy-terminal end of a protein or peptide. 3D cartoon model, secondary structure color scheme, PDB 2v77, white background.
Orange colored ball standing on the twisted wavy purple colored ribbon with blocks. (3d render)
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.
Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
