Detailed explanation-1: -The most common naturally occurring monosaccharides are d-glucose, d-mannose, d-fructose, and d-galactose among the hexoses and d-xylose and l-arabinose among the pentoses.

Detailed explanation-2: -Most carbs occur naturally in plant-based foods, such as grains. Food manufacturers also add carbs to processed foods in the form of starch or added sugar. Common sources of naturally occurring carbohydrates include: Fruits.

Detailed explanation-3: -D and L designations of sugars are based on the position of the hydroxyl on the chiral carbon farthest from the carbonyl group in the Fischer projection of the molecule. All D-sugars have the –OH on the right side and L-sugars have the –OH on the left side.

Detailed explanation-4: -It is important to notice that monosaccharides found in nature belong to the D-series. It is also important to recognize that the sign of a compound’s specific rotation (an experimental number) does not correlate with its configuration (D or L).
