Our Chlorophyll testing helps with the monitoring of rivers, lakes, and ponds. Chlorophyll a contains a magnesium ion encased in a large ring structure known as a chlorin.The chlorin ring is a heterocyclic compound derived from pyrrole.Four nitrogen atoms from the chlorin surround and bind the magnesium atom. Its biosynthesis plays a key role in the adaptation to various light environments. The amount of chlorophyll in the leaves is a great indication of the health of the plant and is almost directly proportional to the Nitrogen content in the leaves. The magnesium center uniquely defines the structure as a chlorophyll molecule. h�ṯ Elle s’est révélée très active contre de nombreux carcinogènes lors des tests.
