Body chemistry refers to the chemical processes and reactions that take place within an organism, particularly related to the functioning of its organs and tissues. It involves the study of how different substances interact with each other in the body, including the way enzymes work to catalyze biochemical reactions, the role of hormones in regulating metabolic processes, and the effects of various chemicals on cellular function. Body chemistry is a complex system that is influenced by factors such as genetics, environment, diet, and lifestyle choices, and plays a critical role in maintaining overall health and well-being.
