519-62-0 Usage

Uses

Extends the absorption spectrum of light-harvesting complexes LHC-I and LHC-II above 700 nm

Uses

Chlorophyll b is a photosynthetic pigment used in the absorption of light energy. Chlorophyl b is involved in photosynthesis and absorbs primarily blue light.

Definition

Chlorophyll b is a?species that is generally characteristic of higher plants and is an accessory chlorophyll that occurs in green algae. Its salts are essential in nutrition, being required for the activity of many enzymes, especially those concerned with oxidative phosphorylation. It is a component of both intra- and extracellular fluids and is excreted in the urine and feces.
