 A) $\left ( C_{22}H_{54}N_{4}O_{21} \right )_{n}$
B) $\left ( C_{21}H_{54}N_{4}O_{22} \right )_{n}$
C) $\left ( C_{22}H_{54}N_{4}O_{13} \right )_{n}$
D) $\left ( C_{22}H_{24}N_{4}O_{21} \right )_{n}$

Answer 1

Hint: The fungal cell wall is a complex, adaptable and flexible structure made essentially out of chitin, α-and β-linked glucans, glycoproteins, and pigments. The fungal cell wall frequently represents the interface for interaction between pathogenic fungi and their host.

Complete answer:
Chitin is a long-chain polymer of N-acetylglucosamine, a subsidiary derivative of glucose. This polysaccharide is an essential component of the cell wall in fungi. Chitin has a formula $\left ( C_{22}H_{54}N_{4}O_{21} \right )_{n}$

Chitin is a modified polysaccharide containing nitrogen; synthesized from units of N-acetyl-D-glucosamine (to be precise, 2-(acetylamino)- 2-deoxy-D-glucose). These units have covalent β-(1→4)- linkages. Subsequently, chitin might be portrayed as cellulose with one hydroxyl group on every monomer replaced with an acetyl amine group.

This structure plays a few capacities, including giving cell rigid and deciding cell shape; digestion; metabolism, ion exchange protection from osmotic pressure; goes about as a supply of carbohydrates and receptors that plays key functions during association and interaction with the host. This considers expanded hydrogen bonding between adjacent polymers, giving the chitin-polymer matrix increased strength.

Chitin is the most abundant plentiful natural compound found in nature and has long-chain polysaccharides with its base unit as an amino sugar. The chitin adds unbending nature and structural support to the fragile cells of the fungus.

Hence, the correct answer to this question is A $\left ( C_{22}H_{54}N_{4}O_{21} \right )_{n}$

Note: The structure of chitin is similar to another polysaccharide, cellulose, shaping translucent nanofibrils or bristles. As far as capacity, it might be contrasted with the protein keratin. Chitin has demonstrated helpful for a few restoratives, mechanical and biotechnological purposes.
