HUMAN NUTRITION

Detailed explanation-1: -Which is not a chemical element needed to build sugars All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates.

Detailed explanation-2: -The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate.

Detailed explanation-3: -Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.

Detailed explanation-4: -As we all know nitrogen is not present in the sugar compound. All the other compounds like carbon, hydrogen, and oxygen are present in the sugar compound.
