Question
What type of biomolecule is glycylglycine, C4H8N2O3?
Question 3
Select one:
- a. carbohydrate
- b. nucleic acid
- c. protein
- d. lipid
Solution
Analyzing Glycylglycine
-
Understanding the Structure
- Glycylglycine is a dipeptide, which is formed by two glycine amino acids linked by a peptide bond. Its molecular formula is C₄H₈N₂O₃.
-
Identifying Biomolecule Categories
- Carbohydrates: Organic molecules made of carbon, hydrogen, and oxygen, usually in a 1:2:1 ratio (e.g., sugars, starch).
- Nucleic Acids: Polymers made of nucleotides, which are the building blocks of DNA and RNA.
- Proteins: Polymers made of amino acids, which are linked by peptide bonds. They play a crucial role in biological functions.
- Lipids: Hydrophobic molecules including fats and oils, generally not composed of monomers.
-
Classifying Glycylglycine
- Since glycylglycine is made up of amino acids, it fits into the category of proteins.
Final Answer
The correct answer is c. protein.
