NEET BIOLOGY

Detailed explanation-1: -Sweet-tasting carbohydrates include the oligosaccharides sucrose and lactose and the monosaccharides glucose, fructose, and galactose.

Detailed explanation-2: -They’re called monosaccharides (simple sugars) and include glucose, fructose, and galactose. Foods containing monosaccharides often taste sweet because taste buds recognize them as sweet.

Detailed explanation-3: -Fructose is the “sweetest” of all sugars (i.e. with the highest intensity of sweetness) and it is most abundant in fruits and honey. On the contrary, galactose, the other monosaccharide, has low sweet intensity and can rarely be found free in foods.

Detailed explanation-4: -Simple carbohydrates are called simple sugars. Sugars are found in a variety of natural food sources including fruit, vegetables and milk, and give food a sweet taste.

Detailed explanation-5: -Hydrogen bonds between sugar and nearby molecules help to determine the level of sweetness. Sugars are thought to owe their sweet taste to the particular pattern of bonds that atoms in sugar molecules form with receptor proteins in taste buds.
