Athletes require bodies that are the best that is possible, all the way from molecules to muscles. By understanding the structure and function of our molecules, athletes can ensure that they are performing at their peak. This knowledge also informs the ways that we all can live our best lives, at all stages of our lives.
Anabolic steroids like testosterone (blue) are among the most common performance-enhancing drugs. They have two major functions: controlling development and maintenance of “male” characteristics and regulating anabolic processes such as synthesis of proteins in muscle cells and formation of oxygen-carrying red blood cells. In the early 1960s, weightlifters and bodybuilders discovered that anabolic steroids improved performance in aerobic and endurance sports. Since then, these compounds have been used (and misused) by amateur and professional athletes. In 1975, the International Olympic Committee placed steroids on their list of banned substances, and most professional sports organizations currently ban their use. The sex hormone-binding globulin, shown here, transports testosterone in the blood from the testes to other tissues.
Researchers around the globe make 3D structures freely available from the Protein Data Bank (PDB) archive. PDB-101 training materials help graduate students, postdoctoral scholars, and researchers use PDB data and RCSB PDB tools. Outreach content demonstrate how PDB data impact fundamental biology, biomedicine, bioengineering/biotechnology, and energy sciences in 3D for a diverse and multidisciplinary user community. Education Materials provide lessons and activities for teaching and learning.
