Which of the following statements concerning carbohydrates is correct? O They can exist in left-handed and right-handed forms, with the left-handed form being dominant in nature. O They are all polyhydroxy aldehydes, polyhydroxyketones, or substances that yield such upon hydrolysis. O They are the most abundant type of biochemical substance in the human body. They all have a sweet taste and therefore are also called sugars.
