Molecular structure of chlorophyll b
Chlorophyll b is a chemical substance whose molecular formula is C55H70MgN4O6, and CAS number is 519-62-0.
Chlorophyll b is a kind of chlorophyll, which absorbs and transmits light energy as one of the antenna pigments of photosynthesis.
Chlorophyll b exists in higher plants, green algae, Euglena and tube algae.
Chlorophyll b has one more carbonyl group than chlorophyll a, so it is more soluble in polar solvents.
The color of chlorophyll b is yellow-green, mainly absorbing blue-violet light.
The maximum absorption wavelength of chlorophyll b is 460-645nm, the emission wavelength is 469nm, and the excitation wavelength is 670nm.
Targeted metabolomics based on mass spectrometry can more sensitively and more accurately quantify target metabolites. This method is mainly used to identify and quantitatively analyze specific metabolites, and has been widely used to analyze and compare multiple target metabolites in different physiological states. It is a key analysis method for researches on green plants to improve nutrition and so on. With decades of experience in mass spectrometry services, Creative Proteomics undertakes the qualitative and quantitative analysis of a variety of plant metabolites, provides accurate and detailed data and analysis reports. From sample extraction and detection to bioinformatics, Creative Proteomics can meet your special needs, and has a good record.
Sample requirements
Algae samples need to prepare 30-40mg freeze-dried powder or 300mg fresh samples.
Plant tissues need to be mixed from more than 3 plants as a sample.
Plant samples need to be freeze-dried, please try to provide more than 3g (fresh weight).
The samples should be stored at -80°, transported on dry ice, and cannot be frozen and thawed repeatedly.
Biological replicates required
If it is a plant or microorganism sample, no less than 6 biological replicates.
