Verified step by step guidance1
Understand the structure and function of macromolecules: Carbohydrates, nucleic acids, lipids, and proteins are all macromolecules, but they are made from different types of building blocks. Carbohydrates are specifically made from simple sugars (monosaccharides).
Recall the definition of simple sugars: Simple sugars, also known as monosaccharides, are the most basic form of carbohydrates. Examples include glucose, fructose, and galactose.
Connect simple sugars to carbohydrates: Carbohydrates are formed when monosaccharides link together through glycosidic bonds in a process called dehydration synthesis. For example, two glucose molecules can combine to form maltose, a disaccharide, and larger chains form polysaccharides like starch or cellulose.
Differentiate carbohydrates from other macromolecules: Nucleic acids are made from nucleotides, lipids are made from glycerol and fatty acids, and proteins are made from amino acids. None of these are composed of simple sugars.
Conclude that carbohydrates are the correct answer: Based on the building blocks of macromolecules, carbohydrates are the only macromolecules made from simple sugars.
