Which of the following statements about proteins and amino acids is incorrect?
Options
- AProteins have peptide bonds in them
- BProteins are present in the acid insoluble pool
- CAmino acids form Zwitter ions
- DPleated structures in proteins form tertiary structure
Correct answer
D. Pleated structures in proteins form tertiary structure
Step-by-step solution
Biomolecules can be acid-insoluble i.e. macromolecules or acid-soluble i.e. micromolecules. Macromolecules are carbohydrates, protein, lipids, and nucleic acids. Proteins contain many amino acids that are linked by peptide bonds and are known as polypeptides. Amino acids contain two functional groups which can form zwitterions. Pleated structures in proteins form secondary structure.
