What are the end products of macronutrients?

The end products of macronutrients are primarily used for energy and building blocks for the body. Carbohydrates are broken down into simple sugars, primarily glucose, which fuels cellular processes. Proteins are digested into amino acids, which are essential for tissue repair and growth. Fats are metabolized into fatty acids and glycerol, serving as a concentrated energy source and aiding in cell structure and signaling.
