Answer: It must be non-nutritive, providing little caloric value, so tiny amounts match the sweetness of much more sugar.
- A It must be non-nutritive, providing little caloric value, so tiny amounts match the sweetness of much more sugar
- B It must contain glucose units similar to those in sucrose so the body metabolises it in a comparable way
- C It must raise blood glucose levels quickly, providing the same energy boost as an equal mass of table sugar
- D It must share most of table sugar's molecular structure, differing mainly by an added phosphate group
Correct answer: A. It must be non-nutritive, providing little caloric value, so tiny amounts match the sweetness of much more sugar
Explanation: Artificial sweeteners are typically non-nutritive, providing little to no caloric value, and are used in very small quantities because they are many times sweeter than sucrose, which makes them suitable for diabetics and dieters.
The hydrophobic hydrocarbon tail of each soap/detergent molecule dissolves into an oily dirt droplet, while the hydrophilic (ionic) head stays in the surrounding water - trapping the grease inside a micelle that rinses away with water.
