Erythropoietin hormone
Erythropoietin. Computer model of a molecule of the hormone erythropoietin. This is a glycoprotein that consists of a single-chain polypeptide of 165 amino acids. Protein structural units are seen as the purple cylinders (alpha helices) and yellow arrows (beta sheets). The molecule has a molecular weight of around 30, 000. Also known as EPO, this hormone is responsible for the regulation of red blood cell production. It is primarily synthesised in the kidneys. It is abused by athletes who use it as a drug to increase their red blood cell levels. This can improve performance in a sporting event, but the thickening of the blood can be dangerous and lead to death

EDITORS COMMENTS
This print showcases a computer-generated model of the erythropoietin hormone, also known as EPO. The intricate structure of this glycoprotein is revealed through purple cylinders representing alpha helices and yellow arrows depicting beta sheets. With a molecular weight of approximately 30,000, this molecule consists of a single-chain polypeptide composed of 165 amino acids. Erythropoietin plays a crucial role in regulating red blood cell production within our bodies. Primarily synthesized in the kidneys, it ensures that our bloodstream maintains an optimal level of these vital cells. However, despite its natural importance, some athletes resort to abusing EPO as a performance-enhancing drug. By artificially increasing their red blood cell levels, they hope to gain an advantage during sporting events. Yet, the misuse of EPO comes with severe risks. While it may temporarily improve athletic performance by boosting oxygen delivery to muscles and enhancing endurance, excessive use can lead to dangerous consequences such as thickening of the blood. This potentially life-threatening condition highlights why responsible usage is essential. Through this stunning visual representation created using computer artwork techniques and scientific knowledge from biochemistry and molecular biology fields, Science Photo Library provides us with valuable insight into the complex world of hormones and their impact on sports performance.
