What are carbohydrates made of?

1. Amino acids

2. Lipids

3. Monosaccharides

4. Nucleotides

The correct answer is: Monosaccharides

Carbohydrates are made of monosaccharides, which are the simplest form of sugars and serve as the basic building blocks for more complex carbohydrates. These monosaccharides can combine to form disaccharides, oligosaccharides, and polysaccharides, which are larger carbohydrate molecules. Examples of monosaccharides include glucose and fructose. In contrast, amino acids are the building blocks of proteins, and lipids are a diverse group of compounds that include fats and oils, characterized by their hydrophobic properties. Nucleotides, on the other hand, are the basic units that make up nucleic acids like DNA and RNA. Understanding these distinctions is important for grasping the roles and structures of different biological molecules.
