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 "What Time Is Love?" Story half the price of a conventional album. Released on 25 September 1989 on LP and CD, "The "What Time Is Love?" Story" used the same basic design lay-out as the "Pure Trance Original" singles, but the colour scheme was altered: lurid pink writing on lurid green (for the vinyl), and lurid green on lurid pink (for the CD). Many commentators have speculated that all of these 'covers' were in fact the work of The KLF themselves. "Q" magazine, for example, commented that "one wonders why all the vocalists sound so alike (and British, even when praising Allah)" and asked of
