What effect do disulfide bonds have on hair?
They change its color
They affect its texture
They increase its length
They reduce its volume
The correct answer is: They affect its texture
Disulfide bonds play a crucial role in determining the texture of the hair. These bonds are formed between the sulfur atoms in the amino acids cysteine, creating a strong link that helps to stabilize the hair's structure. The presence of disulfide bonds contributes significantly to the overall shape, curl, or straightness of the hair. When the hair is chemically treated, such as during perming or relaxing, the disulfide bonds are broken and reorganized, resulting in changes to the hair's texture. This understanding highlights the importance of disulfide bonds in the structure and appearance of hair, making it clear why the correct answer focuses on texture.
