Interpretation:
Bycomparing the carbon skeletons of ß-carotene and lycopene, the similarities and the differences between them should be determined.
Concept Introduction:
Lycopene(C40 H56 ) is a bright red pigment and phytochemical found in red fruits and vegetables like tomatoes, carrots, etc. but not in cherries or strawberries. It is a free radical fighting antioxidant, and it helps in the protection against cancer.
ß-carotene, (C40 H56 ) is a precursor to vitamin A. It is used as a food color because of the yellow color. This compound is found in plants in combination with chlorophyll and assist in the harvesting sunlight or energy.

- I need help with the followingarrow_forwardFor Raman spectroscopy/imaging, which statement is not true regarding its disadvantages? a) Limited spatial resolution. b) Short integration time. c) A one-dimensional technique. d) Weak signal, only 1 in 108 incident photons is Raman scattered. e) Fluorescence interference.arrow_forwardUsing a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40. a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L) b) Calculate the molar absorptivity, a, of the 1645 cm-1 band c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c. (Please provide a full derivation of the equation for x from the equation for I). d) Calculate x for the 1645 cm-1 bandarrow_forward
- For CARS, which statement is not true regarding its advantages? a) Contrast signal based on vibrational characteristics, no need for fluorescent tagging. b) Stronger signals than spontaneous Raman. c) Suffers from fluorescence interference, because CARS signal is at high frequency. d) Faster, more efficient imaging for real-time analysis. e) Higher resolution than spontaneous Raman microscopy.arrow_forwardDraw the major product of the Claisen condensation reaction between two molecules of this ester.
