Beta-amyloid (Abeta) peptide, 3D rendering. Major component of plaques found in Alzheimer's disease. Cartoon representation.
A ball-and-stick molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
The DNA tetrahedron is designed to be mechanically robust; it consists of rigid triangles of DNA helices covalently joined at the vertices
Artificial molecular structure in many colors. Horizontal composition, isolated on white background.
Anthrax oedema factor. Molecular model of oedema factor (EF) from the anthrax bacterium Bacillus antracis complexed with a calmodulin protein molecule. EF is one of three protein components that form the anthrax toxin. It is an enzyme that interferes with water homeostasis, leading to the accumulation of fluid in the tissues. Anthrax most commonly affects cattle, sheep and goats, but can also infect humans.
