Pigments for sale at a market stall in Goa, India. A pigment is a powder used to add color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use.
Anthocyanin pigments are assembled like all other flavonoids from two different streams of chemical raw materials in the cell: One stream involves the shikimate pathway to produce the amino acid phenylalanine, (see phenylpropanoids) The other stream produces three molecules of malonyl-CoA, a C 3 unit from a C 2 unit , [58]
Crustacyanin is a carotenoprotein biological pigment found in the exoskeleton of lobsters and blue crabs and responsible for their blue colour. [ 1 ] β-Crustacyanin (β-CR), is composed of two stacked astaxanthin carotenoids that absorb at λ = 580–590 nm (2.10–2.14 eV).
In biological molecules that serve to capture or detect light energy, the chromophore is the moiety that causes a conformational change in the molecule when hit by light. Healthy plants are perceived as green because chlorophyll absorbs mainly the blue and red wavelengths but green light, reflected by plant structures like cell walls, is less ...
