$C_1-C_4$ glycosidic bond is NOT found in
- Maltose
- Sucrose
- Lactose
- Starch
The Correct Option is B
Approach Solution - 1
The C\(_1\) - C\(_4\) glycosidic bond is typically found in polysaccharides like starch, where glucose molecules are linked by alpha-1,4-glycosidic bonds. However, sucrose, which is a disaccharide composed of glucose and fructose, is linked by an alpha-1,2-glycosidic bond, not a C\(_1\) - C\(_4\) bond. Maltose and lactose contain C\(_1\) - C\(_4\) glycosidic bonds.
So, the correct answer is (B): Sucrose
Approach Solution -2
A glycosidic bond is a covalent bond that connects a carbohydrate (sugar) molecule to another molecule, which could be another sugar or a different type of molecule. The C$_1$-C$_4$ glycosidic bond specifically refers to the bond between the first carbon atom (C$_1$) of one sugar and the fourth carbon atom (C$_4$) of another sugar.
Starch: This polysaccharide consists of glucose units linked by C$_1$-C$_4$ and C$_1$-C$_6$ glycosidic bonds.
Maltose: This disaccharide is made of two glucose units connected by a C$_1$-C$_4$ glycosidic bond.
Sucrose: This disaccharide is made of glucose and fructose, and the glycosidic bond is a C$_1$-C$_2$ bond, not a C$_1$-C$_4$ bond.
Lactose: This disaccharide is made of galactose and glucose, connected by a C$_1$-C$_4$ glycosidic bond.
Thus, the C$_1$-C$_4$ glycosidic bond is NOT found in sucrose, as it has a C$_1$-C$_2$ bond instead.

Concepts Used:
Biomolecules
Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.
- Carbohydrates are chemically defined as polyhydroxy aldehydes or ketones or compounds which produce them on hydrolysis.
- Proteins are another class of indispensable biomolecules, which make up around 50per cent of the cellular dry weight. Proteins are polymers of amino acids arranged in the form of polypeptide chains. The structure of proteins is classified as primary, secondary, tertiary and quaternary in some cases.
- Nucleic acids refer to the genetic material found in the cell that carries all the hereditary information from parents to progeny. There are two types of nucleic acids namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The main function of nucleic acid is the transfer of genetic information and synthesis of proteins by processes known as translation and transcription.
- Lipids are organic substances that are insoluble in water, soluble in organic solvents, are related to fatty acids and are utilized by the living cell.
