Gluconeogenesis is the process of formation of glucose from any non-carbohydrate precursor. If carbohydrate intake does not meet the body's demand for glucose, excess amino acids and glycerol can be converted into glucose via the pathway of gluconeogenesis.
Carbohydrates are easy to breakdown to make energy. But, if there is a carbohydrate deficiency, then the body will start to breakdown amino acids to make energy. The main energy sources are carbohydrates, fats and proteins. In order to keep the body alive, body will breakdown nucleic acids (RNA, DNA) when there is not enough food to make energy.</span>
