Question

Trihydroxypropane is a component of
A.Amino Acid
B.Lipids
C.Nucleic Acids
D.Enzymes

Answer 1

Hint: Trihydroxypropane is commonly known as glycerol and it is an important component in Biological structures. It has a general formula of \[{C_3}{H_8}{O_3}\]. All of the given options are biomolecules. We can find out the correct answer by the method of elimination. The structure of glycerol is as given below:

Complete answer:
The production of the fat takes place in our body by the esterification reaction between the fatty acid and glycerol. Trihydroxypropane is a molecule consisting of three hydroxyl groups. Hydrogen is lost from each of the hydroxyl groups and hydroxide ion is lost from the 3 fatty acid molecules which take place in the presence of a dehydrating agent and thus forms fat. Three molecules of water are liberated in the formation of one molecule of fat and are removed by the dehydrating agent.
From the option given above, we can easily say that amino acids do not contain Trihydroxypropane nor do enzymes or nucleic acids. This means that the only option that we are left with is lipids. Lipids are interchangeably used as fats. Fats are a subgroup of lipids called triglycerides.
Therefore we can say that the correct answer for this question will be option (B).

Note:
Amino acids are the building blocks of proteins and contain an amino group and an acid group along with some organic groups. Enzymes are actually proteins that may or may not contain some metal ions or prosthetic groups. Nucleic acids are the basic building block of DNA and RNA. They are made of sugars, phosphate groups, and bases.
