Question

review time: what is the monomer of carbohydrates? oligosaccahride fatty acid head and fatty acid tails monosaccharide amino acids

Explanation:

To determine the monomer of carbohydrates, we analyze each option:

• Oligosaccharide: It is a type of carbohydrate polymer (oligomer), not a monomer.
• Fatty Acid Head and Fatty Acid Tails: This describes the structure of lipids (like phospholipids), not related to carbohydrates.
• Monosaccharide: By definition, monosaccharides are the simplest sugar units and serve as the monomers for carbohydrates (polysaccharides and disaccharides are formed by linking monosaccharides).
• Amino Acids: These are the monomers of proteins, not carbohydrates.

Answer:

C. Monosaccharide (assuming the orange option is labeled as C; if the options are labeled differently, adjust the identifier but the text is "Monosaccharide")
