There is chemistry within the human and the animal body without which several important functions of the living organism would not be possible. Right from making the food we consume as pulpable and digestible, the enzymes and the fluids present within the biological system play a crucial role in keeping us healthy. The metabolic process within us breaks the food we consume into pieces to extract the proteins and minerals through the chemical process. More than 90% of the human body possesses chemicals like Oxygen, Hydrogen, carbon dioxide, nitrogen, calcium and phosphorus. Biological chemistry regulates every aspect of life. Imbalance in the secretion of hormones would cause chronic diseases like diabetes, Hyper thyroid, depression and a set of neurological disorders including Alzheimer’s and sleeplessness. Ever-growing body of research in this field helps us to maintain balance among the biological chemical process taking place within the human body.
