Definition: Geranin is a type of amino acid found in certain types of plant and animal tissues, particularly in plants like soybean and wheat. It plays a role in protein synthesis and has been used as an indicator of muscle development. However, it should be noted that geranin does not have any known health effects and generally does not cause significant side effects. If you're looking for information on the use or toxicity of this substance, I recommend consulting with healthcare professionals.
