What is a chromophore molecule?
A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light.
What is chromophore and example?
A chromophore is the section of a molecule that causes us to see color. The chromophore portion of the molecule will have alternating double bonds, or conjugated double bonds. For example, beta-carotene, the molecule responsible for the color in carrots, has many double bonds.
How do you tell if a molecule has a chromophore?
A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light.

What is the chromophore made of?
chromophore, a group of atoms and electrons forming part of an organic molecule that causes it to be coloured.
What are the 5 chromophores?
Examples of endogenous chromophores are melanin, haemoglobin, (oxy haemoglobin, de-oxyhaemoglobin and meth haemoglobin), water, protein, peptide bonds, aromatic amino acids, nucleic acid, urocanic acid and bilirubin.
Is water a chromophore?
Perhaps the most dominant chromophore in biology which absorbs via vibrational transitions is water. In the infrared, the absorption of water is the strongest contributor to tissue absorption.
Which group is an example of chromophore?
Azo group is a chromophore.
What are the 4 chromophores?
These chromophores are predominantly haemoglobin, melanin, water and foreign bodies. The chromophore haemoglobin will selectively absorb light at 595nm (if using a pulsed dye laser) and the heat generated will potentially destroy the blood vessel.
