Dextrose solution doesn't have a suitable amount of proteins, fats (lipids) and micronutrients (vitamins and minerals)
Explanation:
Dextrose is a type of simple carbohydrate (monosaccharide), which is prescribed and administrated intravenously in cases of dehydration and low blood sugar levels. Dextrose forms part of nutrition in the normal diet, but it is insufficient to obtain all the required nutrients in patients following surgery. Intravenous nutrition must include proteins, lipids and micronutrients such as vitamins and minerals (especially zinc in order to synthesize collagen which acts to accelerate wound healing). For this purpose, a protein-dextrose solution supplemented with lipid emulsion is well-suited for providing short-term nutritional support for patients following surgery.
Their course of action in altering metabolism is very similar because both of them interact with intracellular receptors (primarily the cytosolic receptors present in cytoplasm of the cell) and translocate into the nucleus for performing their desired goal (likely to synthesize a mRNA which can then be turned into a protein to get a desired action going)
