Is DNA a carbohydrate

DNA does not have the code to directly make carbohydrates. DNA codes for nucleic acids that are building blocks for proteins. Proteins are complex molecules that are able to act as enzymes and building blocks for the most important structural components of cells. Complex carbohydrates can be large molecules but they are small compared to proteins. Proteins can act as enzymes instrumental in breaking down carbohydrates into simpler sugars that fuel the energy requirements of the cellular machinery. This energy ultimately comes from the atomic level where electron transfer is mediated by molecular machines that store energy in ATP and extract that energy in controlled ways so that muscles contract and nerves can fire when needed. Carbohydrates and fats existed before proteins came into existence. There are free educational videos that beautifully illustrate the structure of matter from the atomic level to the large inorganic molecular level and then make the transition to the much greater complexity of organic molecules and ultimately to the largest molecules, the proteins. Proteins are manufactured in trillions of linear assembly lines and then they quickly fold up into complex structures that keep life viable. Thanks for the question.
