Which of the following is NOT one of the common chromophores in the body?

1. Melanin

2. Hemoglobin

3. Lymph

4. Water

The correct answer is: Lymph

Lymph is not considered one of the common chromophores in the body. Chromophores are molecules that can absorb light at specific wavelengths and are responsible for the color of tissues. Melanin is a pigment found in the skin, hair, and eyes, and it effectively absorbs ultraviolet light, providing some protection against sun damage. Hemoglobin is the protein in red blood cells that carries oxygen and has a distinct ability to absorb light, particularly in the visible spectrum. Water, while not a pigment, is considered a chromophore due to its ability to absorb light at various wavelengths, especially in the infrared range which can affect heat in tissues. In contrast, lymph does not have significant light-absorbing properties like the others and therefore does not function as a chromophore. Its role is primarily related to the immune system and fluid balance rather than color or light absorption.
