Answer:
Macromolecules are important for the body and therefore, are used frequently. For example, “macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions.” There are four major types of macromolecules, those of which are as follows; proteins, carbohydrates, nucleic acids, and lipids. All of these play these important roles in the life of a cell. Macromolecules such as protein, carbohydrates and fats are bigger in size which can not be absorbed by the cell or the body, so these macromolecules are first broken down into micro-molecules, such as amino acids, glucose and fatty acids, etc. Protein is converted into amino acids, carbohydrates are converted into glucose, and fats are converted into fatty acids by the action of different enzymes. Proteins use amino acids which provide cell structure, send chemical signals, and speed up chemical reactions. Nucleic acids use nucleotides that store and pass on genetic information. Carbohydrates use monosaccharides (aka simple sugars) to provide cells with quick, short-term energy and a source of dietary fiber. Lipids use fatty acids and glycerol to provide cells with long-term energy, and they make up biological membranes. That is how macromolecules are used in the body.
