Degradation of the Molecular Basis of Life During the Aging Process

Aging is a chronic, destructive process characterized by the progressive breakdown of the body, leading to a loss of control over homeostasis. Glucose is the most important metabolite involved in metabolism and maintaining homeostasis in the human body. Glucose-based energy metabolism is fundamental to the activity and structural changes in the brain, which is the main regulator of life processes. Disturbances in energy metabolism and glucose-dependent metabolic processes have a decisive impact on the aging process. Age-related deficiency of the coenzyme NAD, which regulates glucose metabolism in neurons, leads to irreversible changes in the brain, culminating in senescence. Research on NAD precursors offers hope that although we cannot completely halt the aging process, NAD supplementation may enable healthy aging.
