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
The Colour of Spring The Colour of Spring The Colour of Spring is the third studio album by English rock band Talk Talk, released in 1986. Musically, "The Colour of Spring" was a major step away from the synthesised pop of early Talk Talk, with a greater focus on guitars, pianos, and organs on such songs as "Life's What You Make It", "Living in Another World" and "Give It Up". It had a sound described by the band as much more organic than their earlier records, with the improvisation that was to dominate on their later works already apparent in the recording process. The
