Avibactam is a diazobicyclooctane inhibitor of gram-negative and gram-positive bacteria.  Avibactam (red) inhibits the bacterial enzyme beta-lactamase (blue) of Clostridioides difficile.
New variant of coronavirus, mutation in the virus's spike protein
Low-Fiber Diet Risks Gut Health & Allergies
Molecular model of Thymine, 1 of 4 nucleobases to form DNA
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
Isolated Proteasome with protein conjugated with ubiquitin 3d rendering
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.
