Example of a protein containing primarily beta-sheets and also identify the protein mentioned is globular or fibrous. Concept introduction: Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins. Amino functional group is ( − N H 2 ) and carboxyl functional group is ( − C O O H ) and a R group is considered as side chain, when all these are bonded to same carbon atom. Secondary structure of protein is the repeating structural patterns ( α-helix and β-sheets ) formed by hydrogen bonding between backbone atoms of the neighboring segments of protein. α-helix is the secondary protein structure in which a protein chain form a right handed coil stabilizes by hydrogen bonds between peptide groups along its backbone. Fibrous protein is a tough, water insoluble protein whose protein chains form fibers or sheets. Globular protein is a water soluble protein whose chain is folded in a compact shape.

Interpretation Introduction

Interpretation:

Example of a protein containing primarily beta-sheets and also identify the protein mentioned is globular or fibrous.

Concept introduction:

Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.

Amino functional group is (−NH2) and carboxyl functional group is (−COOH) and a R group is considered as side chain, when all these are bonded to same carbon atom.

Secondary structure of protein is the repeating structural patterns (α-helix and β-sheets) formed by hydrogen bonding between backbone atoms of the neighboring segments of protein.

α-helix is the secondary protein structure in which a protein chain form a right handed coil stabilizes by hydrogen bonds between peptide groups along its backbone.

Fibrous protein is a tough, water insoluble protein whose protein chains form fibers or sheets.

Globular protein is a water soluble protein whose chain is folded in a compact shape.

The carbon-nitrogen peptide bond is rigid, but rotation can take place about the bond between the nitrogen and α-carbon atoms and the bond between the α-carbon and the carbonyl carbon atom. These bond angles define the conformation of the peptide chain. Consider the Ramachandran plot shown to answer both questions.
