It is responsible for the low level of basal glucose uptake required to sustain respiration in all cells. Levels in cell membranes are increased by reduced glucose levels and decreased by increased glucose levels. GLUT1 expression is upregulated in many tumors. GLUT2: Is a bidirectional transporter, allowing glucose to flow in 2 directions.
2-Chlorobenzaldehyde (o-chlorobenzaldehyde) is an organic compound with the formula ClC 5 H 4 CHO. It is one of three isomeric monochlorinated benzaldehyde . 3-Chlorobenzaldehyde and 4-chlorobenzaldehyde are the other isomers.
Chlorobenzaldehyde may refer to: 2-Chlorobenzaldehyde (o-chlorobenzaldehyde) 3-Chlorobenzaldehyde (m-chlorobenzaldehyde) 4-Chlorobenzaldehyde (p-chlorobenzaldehyde)
The FT-IR spectra were recorded using a Nicolet 170SX or a JASCO FT/IR-410 spectrometer. For spectra recorded in the Nicolet spectrometer, the data were stored at intervals of 0.5 cm −1 in the 4,000 – 2,000 cm −1 region and of 0.25 cm −1 in the 2,000 – 400 cm −1 region and the spectral resolution was 0.25 cm −1.
Fluorescent glucose biosensors are devices that measure the concentration of glucose in diabetic patients by means of sensitive protein that relays the concentration by means of fluorescence, an alternative to amperometric sension of glucose. Due to the prevalence of diabetes, it is the prime drive in the construction of fluorescent biosensors.
The Fourier transform with respect to provides the excitation spectrum (frequency ). Two-dimensional infrared spectroscopy (2D IR) is a nonlinear infrared spectroscopy technique that has the ability to correlate vibrational modes in condensed-phase systems. This technique provides information beyond linear infrared spectra, by spreading the ...
By applying intense tunable IR lasers, like IR-OPOs or IR free electron lasers, the wavelength dependence of the IRMPD yield can be studied. [5] [6] This infrared photodissociation spectroscopy allows for the measurement of vibrational spectra of (unstable) species that can only be prepared in the gas phase. Such species include molecular ions ...
