Detailed Solution

The given statement is true.
Concept: We are aware that proteins are made up of alpha amino acid polymers and are joined together by peptide bonds. Proteins are divided into globular and fibrous proteins.
To better understand how pH affects the structure of proteins, let's talk about denaturation of proteins. We are aware that native proteins are those found in biological systems that have distinct biological activity and three-dimensional structure. When a protein is exposed to physical changes, such as a change in temperature or pH, the hydrogen bonds become disturbed, which causes the globules to unfold and the helix structure to uncoil. The biological activity of proteins suffers as a result. Protein denaturation is the term used to describe this phenomenon. Proteins' primary structure is unaffected but their tertiary and secondary structures are destroyed during denaturation.
Hence, the given statement is true.
