Acyl-Lipid Δ⁶-Desaturase May Act as a First FAD in Cyanobacteria

Biomolecules, 2022
Fatty acid desaturases (FADs) play important roles in various metabolic and adaptive pathways in all living organisms. They represent a superfamily of oxygenases that introduce double bonds into the acyl chains of fatty acids (FAs).

High-Frequency Modulation Spectroscopy with a THz Quantum-Cascade Laser [PDF]

, 2013
A terahertz absorption spectrometer with a quantum-cascade laser (QCL) for high-resolution molecular spectroscopy is realized. The spectrometer is based on highfrequency (up to 50 MHz) modulation of the QCL frequency.

Effects of NMR spectral resolution on protein structure calculation [PDF]

, 2013
Adequate digital resolution and signal sensitivity are two critical factors for protein structure determinations by solution NMR spectroscopy. The prime objective for obtaining high digital resolution is to resolve peak overlap, especially in NOESY ...
