The main hormones produced by the thyroid gland are thyroxine or tetraiodothyronine or T4 and triiodothyronine or T3 3d rendering
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.
Thioredoxin antioxidant enzyme. 3D illustration. Atoms shown as spheres with conventional color coding.
Metal DNA formula on white background. 3D render.
PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.

One of hormone produced by the thyroid gland is thyroxine or t4 3D rendering
A ball and stick model of a molecule of Human Interferon. Interferons are proteins important in the working of the immune system and are produced in large numbers in the presence of viruses, bacteria, tumors and parasites.  Interferons are used in drugs to combat cancer, multiple sclerosis, hepatitis B and C and other diseases. Isolated on white.
