Lycopene the structure of the molecule was determined by 1931. In its natural, all-"trans" form, the molecule is long and straight, constrained by its system of 11 conjugated double bonds. Each extension in this conjugated system reduces the energy required for electrons to transition to higher energy states, allowing the molecule to absorb visible light of progressively longer wavelengths. Lycopene absorbs all but the longest wavelengths of visible light, so it appears red. Plants and photosynthetic bacteria naturally produce all-"trans" lycopene. When exposed to light or heat, lycopene can undergo isomerization to any of a number of "cis"-isomers, which have a
Blue Is the Colour Blue Is the Colour Blue Is the Colour is the fifth studio album from English band The Beautiful South, released in October 1996 through Go! Discs and in America through Ark 21 Records. Following the two singles "Pretenders to the Throne" and "Dream a Little Dream", which never featured on any album until the release of the second greatest hits "Solid Bronze" in 2001, it was named after a pub in Sheffield.
