										Most carbohydrates absorb very little light in the ultraviolet and visible spectral region. Any functional groups present, either naturally or chemically introduced, can act as chromophores or flourophores ( a group of atoms and electrons forming part of an organic molecule that causes it to be coloured). Virtually all carbohydrates contain multiple chiral centers and are thus optically active. Many carbohydrates are enantiomers, i.e., D- and L-glucose, or diastereomers. Most reducing sugars are exhibit mutarotation when dissolved in water. Mutarotation is the change in specific rotation of a chiral compound due to epimerization. Circular dichroism (CD), Optical rotary Dispersion (ORD), and infrared (IR) spectroscopy have been used to study the conformation of carbohydrates.
