Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What elements do most carbohydrates contain
A
Carbon, Nitrogen, oxygen
B
Carbon, Nitrogen, Oxygen, Phosphorous
C
Nitrogen, Oxygen
D
Oxygen
Explanation: 

Detailed explanation-1: -All carbohydrates contain carbon, hydrogen, oxygen.

Detailed explanation-2: -Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n.

Detailed explanation-3: -Carbohydrate classification The basic building block of a carbohydrate is a simple union of the elements carbon, hydrogen and oxygen (CHO). The chemical definition of a carbohydrate is any compound containing these three elements which typically has twice as many hydrogen atoms as carbon and oxygen atoms (CH2O).

Detailed explanation-4: -This view represents these molecules simply as “hydrated” carbon atom chains in which water molecules attach to each carbon atom, leading to the term “carbohydrates.” Although all carbohydrates contain carbon, hydrogen, and oxygen, there are some that also contain nitrogen, phosphorus, and/or sulfur.
