What is the composition for each of the macronutrients?

Macronutrients consist of three primary categories: carbohydrates, proteins, and fats. Carbohydrates are made up of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. Proteins are composed of amino acids, which contain carbon, hydrogen, oxygen, and nitrogen, while some may also include sulfur. Fats, or lipids, primarily consist of carbon and hydrogen atoms, forming fatty acid chains and glycerol.
