Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures.

Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.

The location of the atoms, groups or ions relative to one another in a molecule, as well as the number, type and location of covalent bonds.

The characteristic three-dimensional shape of a molecule.

Devices implanted to control intraocular pressure by allowing aqueous fluid to drain from the anterior chamber. (Hoffman, Pocket Glossary of Ophthalmologic Terminology, 1989)
