Chlorophyll a Analysis Service

Online Inquiry

Chlorophyll a, an organic compound, is a waxy solid.

Its molecular formula is C55H72MgN4O5.

Its CAS number is 479-61-8.

Chlorophyll a exists in all green plants, and the maximum absorption band is red light and blue-violet light.

In photosynthesis, the role of most of chlorophyll is to absorb and transmit light energy, and only a few chlorophyll a in the excited state can convert light energy into electrical energy.

Chlorophyll a is one of the important pigments of phytoplankton. It accounts for 1% to 2% of the dry weight of organic matter. It is an indicator for estimating primary productivity and biomass, and it is also a must-test item for red tide monitoring.

Molecular structure of chlorophyll a Molecular structure of chlorophyll a

Chlorophyll a is an edible green pigment used in cakes, beverages, liqueurs, etc.

Chlorophyll a also has a positive effect on the human body. It is the direct raw material of heme for humans and animals. Its perfect combination with iron is also the best partner for the treatment of iron deficiency anemia.

The molecular structure of chlorophyll a consists of 4 pyrrole rings connected by 4 methylenyl groups (=CH—) to form a cyclic structure called porphyrin (the ring has a side chain).

Targeted metabolomics is mainly used to identify and quantitatively analyze specific metabolites in samples, this method 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. Based on the LC-MS/MS platform, Creative Proteomics use analytical standard detection methods to perform accurate qualitative and quantitative analysis on the pre-screened and validated or identified potential biomarkers (chlorophyll a).

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).
