Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
A ball and stick model of Eicosapentaenoic Acid or EPA. It is an omega-3 polyunsaturated fatty acid. It is introduced into the diet by eating oily fish. When it comes to fat, there’s one type you don’t want to cut back on: omega-3 fatty acids. Two crucial ones - EPA and DHA - are primarily found in certain fish.

Abstract shape with particles on blue background. Digitally generated image.
p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.
