Question

Which type of bond is found between amino acids in a protein chain?

• A. Hydrogen bond
• B. Peptide bond
• C. Ionic bond
• D. Glycosidic bond

Hint:

Amino acids are linked by peptide bonds. Without peptide bonds, proteins wouldn’t exist!

Answer 1

The Correct Option is B

To solve the problem, we need to identify the type of bond that links amino acids together to form a protein chain.

1. Understanding Amino Acids and Proteins:

- Proteins are made up of smaller building blocks called amino acids.
- Amino acids join together in a chain to form proteins.
- The bond that connects one amino acid to another is crucial for protein structure.

2. The Bond Between Amino Acids:

- The bond formed between the amino group (–NH₂) of one amino acid and the carboxyl group (–COOH) of another amino acid is called a peptide bond.
- This bond is created through a chemical reaction called a condensation reaction or dehydration synthesis, where a molecule of water is released.
- A chain of amino acids linked by peptide bonds is called a polypeptide, which folds to form a functional protein.

3. Summary:

- Peptide bonds hold amino acids together in proteins.
- These bonds give proteins their primary structure.

Final Answer:

The type of bond found between amino acids in a protein chain is a peptide bond.
