Question

Proteins undergo polymerization to form long chains and are organized in the structure of a complex molecule. What kind of bonding is involved in their structure?

• A. Covalent bonding
• B. Ionic bonding
• C. Hydrogen bonding
• D. Van der Waals bonding

Hint:

Proteins are primarily held together by covalent peptide bonds, and secondary structures like alpha helices and beta sheets are stabilized by hydrogen bonds.

Answer 1

The Correct Option is A

Step 1: Understanding the Question.
The question asks about the bonding type involved in the structure of proteins. Proteins are made of amino acids linked by covalent bonds.
Step 2: Analyzing the Options.
- (A) Covalent bonding is correct because amino acids are connected by peptide bonds, a type of covalent bond.
- (B) Ionic bonding is not the main type of bonding in proteins.
- (C) Hydrogen bonding plays a role in protein folding but is not the primary bonding type.
- (D) Van der Waals forces are weak and also contribute to protein structure but are not the main force.
Step 3: Conclusion.
The correct answer is (A) Covalent bonding.
