    This image illustrates the phenomenon that has enabled astronomers to indirectly detect dozens of planets, even if the planets themselves are too small to be seen directly. As a planet passes in front of its star, the star's light dips just a little - but it can be measured, and the presence of a planet thus inferred.

    Haemoglobin, molecular model. Haemoglobin is a metalloprotein that transports oxygen around the body in red blood cells. Each molecule consists of iron-containing haem groups (sticks) and globin proteins (amino acid chains, coils). Each globin protein is wrapped around a haem group, protecting it from being oxidised and destroyed by the oxygen it is intended to transport. The iron within each haem

    Human growth hormone (hGH), molecular model. hGH is produced in the anterior pituitary gland of the brain. It binds to specific receptors on cells in the body to stimulate growth, especially in childhood. It is also involved in strengthening bone, increasing muscle mass, reducing glucose uptake by the liver and promoting the breakdown of body fat.

    Human serum albumin, molecular model. Albumin is the most abundant protein in human blood plasma. It is seen here complexed with stearic acid, a saturated fatty acid. One of albumin's functions is to transport fatty acids to the liver. It also binds to molecules, including calcium, some hormones and drugs, to prevent them from being filtered from the blood by the kidneys. Albumin is also important
