PETase (left) degrades  polyethylene terephtalate (PET) into monohydroxyethyl terephthalate (MHET) and MHETase degrades MHET ethylene glycol (EG) and terephthalic acid (TPA). The substrates in the binding sites are depicted in red.
Model of human Insulin, a hormone to regulate carbohydrate and fat metabolism
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Abarelixis an injectable gonadotropin-releasing hormone antagonist which is marketed in Germany. 3d illustration
protein G−DNA conjugate an antibody to the intended area on the surface of bioassay chips or particles; 3d rendering
3d rendered Gastric inhibitory polypeptide (GIP, glucose-dependent insulinotropic peptide) endocrine protein hormone, 3D 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.
