AMonosaccharides, disaccharides and polysaccharides
BMonosaccharides, polypeptides and polysaccharides
CMonosaccharides, disaccharides and triglycerides
DMonosaccharides, disaccharides and polynucleotides
Answer & Solution
Correct answer: A. Monosaccharides, disaccharides and polysaccharides
1. Carbohydrates are grouped by how many sugar units they contain.
2. One unit is a monosaccharide, two units make a disaccharide, and a long chain is a polysaccharide.
3. Polypeptides are chains of amino acids and polynucleotides are chains of nucleotides, so neither is a carbohydrate class.
4. Triglycerides are fats, which belong to the lipids.
