Cytochrome P450 molecule. CYP 3A4 is the most promiscuous of the human CYP enzymes. Molecular model. 3D rendering. Illustration
A ribbons + ball-and-stick model of a molecule of Human Leptin, a hormone produced by body fat. Normally, the amount of leptin in the body is proportional to the amount of fat. Leptin reduces appetite and the absence of leptin results in increased food intake and obesity.

3D rendering of BODIPY: A bright dye for research, glowing for cell imaging.
A molecular model of a Ribosome. Ribosomes are present in the cells of all forms of life, from bacteria to humans. DNA is copied to RNA, and Ribosomes read the instructions encoded in RNA to build proteins. Ribosomes were first observed in the 1950s, but the detail of their complex structure wasn't known until the early 2000s.
