Carbohydrates are classified into three subtypes: monosaccharides, polysaccharides and:
ATriglycerides
BPhospholipids
COligopeptides
DDisaccharides
Answer & Solution
Correct answer: D. Disaccharides
1. The subtype depends on how many monomer units the molecule holds.
2. One unit is a monosaccharide and many units make a polysaccharide.
3. Two units joined together form a disaccharide.
4. Triglycerides and phospholipids are lipids, and oligopeptides are short protein chains.
