Which of the following is true about disaccharides?

Disaccharides are comprised of two monosaccharides that are chemically bonded together through a glycosidic linkage. This bond forms during a condensation reaction, where a molecule of water is released. Common examples of disaccharides include sucrose (table sugar), lactose (found in milk), and maltose (found in malted foods).

The other options do not accurately describe disaccharides: they cannot be classified as single sugar molecules, since they consist of two monosaccharide units. While disaccharides are indeed found in both plant and animal sources, stating they are only found in animal sources is incorrect. Lastly, while many disaccharides do have a sweet taste, it is not a definitive characteristic across all disaccharides; for instance, maltose is less sweet compared to others. Therefore, the statement about disaccharides consisting of two monosaccharides is accurate and highlights their fundamental structure.
