Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organic compounds end in “-ose” such as glucose and sucrose?
A
Carbohydrates
B
Lipids
C
Nucleic Acids
D
Proteins
Explanation: 

Detailed explanation-1: -Simple carbohydrates which are sweet and soluble in water are also known as sugars or disaccharides and the ending of the names of most sugars is-ose. Thus, we have such names as sucrose for ordinary table sugar, glucose for principal sugar in blood and maltose for malt sugar.

Detailed explanation-2: -Note that sugar names often end in “ose”: sucrose, dextrose, maltose, lactose, etc. Sucrose is the chemical name for sugar that comes from the cane and beet sugar plants.

Detailed explanation-3: -Simple carbohydrates, such as glucose, lactose, or dextrose, end with an “-ose.” Simple carbohydrates can be classified based on the number of carbon atoms in the molecule, as with triose (three carbons), pentose (five carbons), or hexose (six carbons).

Detailed explanation-4: -Sugar molecules ending in “ose” (dextrose, fructose, glucose, lactose, maltose, sucrose)

Detailed explanation-5: -Words ending in-ose: The suffix-ose is used in biochemistry to form the names of sugars. In Latin this suffix means “full of”, “abounding in”, or “like”. Sucrose, dextrose, glucose, maltose, fructose, and lactose are all scientific names for different types of sugar.
