Conclusion
library match to a polyunsaturated fatty acyl-adenine dinucleotide conjugate; observed spectral features are dominated by long-chain alkane/lipid character
Library directionConclusion
- A related literature source also assigns 1460 cm⁻¹ to aromatic ring stretch [3]; while that assignment is not primary here, it indicates the band’s potential multiplicity and does not contradict the dominant alkyl interpretation.
- The strong pair at 2926 and 2858 cm⁻¹ is assigned to asymmetric and symmetric CH₂ stretching vibrations of long alkyl chains, consistent with the fatty acyl moiety of the library candidate and with direct literature assignments of similar bands to lipid alkyl chains [2,4].
- Related literature fragments consistently identify the 2926/2858 cm⁻¹ pair as CH₂ stretches of lipid alkyl chains and note the absence of carbonyl, hydroxyl, or other functional group absorptions, in agreement with the present spectrum.
