Chemical Reactions in the Human Brain: A Biochemical Perspective on Neurotransmission, Oxidative Stress, and Neurodegenerative Disorders

Abstract

Chemical reactions in the human brain regulate cognition, memory, emotions, motor coordination, and consciousness. Neurochemical pathways involving neurotransmitters, ion exchange, enzymatic catalysis, oxidative metabolism, and inflammatory signaling play fundamental roles in maintaining neural homeostasis. Disturbances in these biochemical reactions contribute to neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, epilepsy, depression, and schizophrenia. This study presents a novel interdisciplinary investigation integrating neurochemistry, reaction kinetics, oxidative stress pathways, and mathematical modeling to analyze the dynamics of chemical reactions occurring in the human brain. The proposed framework examines neurotransmitter synthesis, synaptic transmission, free radical generation, mitochondrial dysfunction, and neuroinflammation using systems biology approaches. The study highlights the role of dopamine oxidation, glutamate excitotoxicity, and amyloid-beta aggregation in neuronal damage. Furthermore, recent advances in neurochemical imaging, nanomedicine, and computational neuroscience are reviewed. The findings suggest that integrating biochemical kinetics can improve prediction, diagnosis, and therapeutic strategies for neurological disorders.
