Question

(01.02 mc)
what type of molecule is represented by the model below?
o a fat
o b carbohydrate
o c steroid
o d protein

Explanation:

• Fats are triglycerides, formed by glycerol and fatty acids, not having this ring - like structure.
• Carbohydrates have a general formula \(C_x(H_2O)_y\) and are usually in the form of simple sugars (like glucose with a hexagonal structure but different from this fused - ring and side - chain structure) or polymers of simple sugars.
• Proteins are polymers of amino acids, with peptide bonds \(-CO - NH-\), and their structures are based on amino - acid sequences and folding, not this type of ring - and - side - chain structure.
• Steroids have a characteristic four - ring (three six - membered rings and one five - membered ring) structure, which is evident in the given molecular model.

Answer:

C. Steroid
