Which bond joins two monosaccharides together to form a disaccharide?
Answer and explanation
Correct answer: A. A glycosidic bond formed in a condensation reaction
- Step 1: Disaccharides form when two monosaccharides join with the loss of one water molecule (condensation). Step 2. The bond formed between the two sugar units is a glycosidic bond. Answer: A glycosidic bond formed in a condensation reaction. Why not the others: peptide bonds join amino acids; hydrolysis breaks glycosidic bonds rather than making them; ester bonds join glycerol and fatty acids.
