Verified step by step guidance

Step 1: Understand the definition of carbohydrates. Carbohydrates are organic molecules composed of carbon (C), hydrogen (H), and oxygen (O) in a specific ratio, typically following the general formula (CH₂O)n, where n is the number of carbon atoms.

Step 2: Analyze the molecular formula of each compound provided in the question. For example, Adenine ($C_5H_5N_5$) contains nitrogen (N), which is not characteristic of carbohydrates. Cholesterol ($C_{27}H_{46}O$) has a high ratio of hydrogen to oxygen, which does not fit the typical carbohydrate formula. Glycine ($C_2H_5NO_2$) contains nitrogen and is classified as an amino acid, not a carbohydrate.

Step 3: Examine the molecular formula of Glucose ($C_6H_{12}O_6$). It fits the general formula of carbohydrates (CH₂O)n, where n = 6. The ratio of hydrogen to oxygen is 2:1, which is characteristic of carbohydrates.

Step 4: Confirm that Glucose is a monosaccharide, a simple sugar, and a fundamental carbohydrate. It serves as a primary energy source in biological systems and is classified as a carbohydrate based on its structure and function.

Step 5: Conclude that among the given options, Glucose ($C_6H_{12}O_6$) is the compound classified as a carbohydrate based on its molecular formula and characteristics.
