Quizplus · Accepted Answer

Carbohydrates, such as glucose or dextrose, are the main source of energy in parenteral nutrition. They are rapidly absorbed and provide a quick source of energy for the body. Protein and fat can also be included in parenteral nutrition, but they serve other purposes such as tissue repair and maintenance. Amino acids are the building blocks of protein, and while they may be included in parenteral nutrition, they do not provide energy on their own.
