Scientific Explanation:
There are four main macromolecules that we eat – carbohydrates, lipids, proteins and nucleic acids. Each of these macromolecules plays an important role in our bodies and provides us with energy and essential nutrients. Carbohydrates are essential for providing our bodies with energy. They are broken down into glucose, which is then used by our cells for energy. Complex carbohydrates, such as those found in whole grains, also provide our bodies with important vitamins and minerals. Lipids are another important macromolecule that we eat. They are a major source of energy and help to keep our cell membranes healthy. Fatty acids, which are a type of lipid, are also essential for many biochemical reactions in our bodies. Proteins are essential for the growth and repair of our bodies. They are also involved in many biochemical reactions and help to transport nutrients and oxygen around our bodies. Amino acids, which are the building blocks of proteins, are also essential for our bodies. Nucleic acids, such as DNA and RNA, are essential forthe function of our cells. They are also involved in the synthesis of proteins and the regulation of gene expression.
