The absorbed food is utilized by the body through various metabolic processes. Amino acids from proteins contribute to the synthesis of new proteins for growth and repair. Glucose, derived from carbohydrates, serves as a primary energy source for cellular activities. Fatty acids obtained from fats contribute to energy production, cell membrane formation, and hormone synthesis. Vitamins and minerals play vital roles as cofactors in enzymatic reactions and maintain physiological functions. Nutrients are distributed via the bloodstream to tissues and organs, where they support cellular activities, promote growth, and maintain overall homeostasis. Excess energy may be stored as glycogen or fat for future use.
