Question

Which of the following statements about amino acids is incorrect?A turn or kink in a protein is more likely to be induced by a proline than by a glycine.At typical cellular pH, the R groups of basic amino acids are positively charged.The bridge between cysteines, which connects parts of a protein, is a stable but non-covalent interaction.Not every amino acid is asymmetric.The more glycines that are found in a polypeptide's primary sequence, the more flexible the backbone of that polypeptide.

Answer 1

Answer:

The correct answer is The bridge between cystein which connects parts of a protein is stable but non covalent interaction.

Explanation:

Disulfide bond link the sulfhydryl group of two adjacent cystein residues in a protein structure.

     Dulsulfine bond is stable but is not a non covalent interaction.Disulfide bond itself is a covalent interaction.
