Inside protein molecule
Cyclooxygenase (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme (specifically, a family of isozymes, EC 1.14.99.1) that is responsible for formation of prostanoids, including thromboxane and prostaglandins such as prostacyclin, from arachidonic acid. Two COX enzymes are known to be involved in prostaglandin synthesis, COX-1 and COX-2. COX-1 generates prostaglandins that are involved in the protection of gastrointestinal mucosa, while COX-2 generates prostaglandins that mediate inflammation and pain in sites throughout the body.

Molecular model of lactose, a disaccharide sugar in milk.
Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.
A space-filling molecular model of collagen, a fibrous protein that provides structural support in animals. It has a distinctive triple helix structure. Isolated on black.
Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange),  that is aggregated to amyloid beta fibrils, which build up amyloid plaques.
