A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
3D cartoon model, PDB 5wn4, white background
The crystal structure of the tumor marker protein. The 3D model of the biological macromolecule.
Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.
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.
Beta-amyloid (Abeta) peptide, 3D rendering. Major component of plaques found in Alzheimer's disease. Cartoon representation.
Freshness capsule
The DNA tetrahedron is designed to be mechanically robust; it consists of rigid triangles of DNA helices covalently joined at the vertices
Molecular model of Adenosine triphosphate,  or Adenosine-5'-triphosphate (ATP)
Trehalose is a sugar consisting of two molecules of glucose. It is also known as mycose or tremalose. 3d illustration
A molecule of sucrose, showing thermal ellipsoids.
3D cartoon and Gaussian surface models. PDB 1ok3, white background.
A ball and stick model of a molecule of gamma-Cyclodextrin. Composed of eight glucose sugar molecules bound into a ring structure, cyclodextrins are easily made from simple starch. The large ring can bind smaller molecules within it, making Cylodextrins useful in drug-delivery applications and also to clean up toxins (such as heavy metals) in the environment. Currently, gamma-Cyclodextrin is being considered as a structure which can bind to and hold carbon dioxide gas for carbon capture and storage as a way to manage the effect of excess carbon dioxide on the climate.
