The liver plays a crucial role in metabolizing nutrients by processing carbohydrates, proteins, and fats. It converts excess glucose into glycogen for storage and regulates blood sugar levels. The liver is also responsible for synthesizing cholesterol and producing bile, which aids in fat digestion. In terms of protein metabolism, it converts amino acids into usable forms and removes toxic substances through a process called detoxification. Overall, the liver’s efficiency in metabolizing nutrients is vital for maintaining homeostasis and supporting overall bodily functions.
