An interesting fact about chlorophyll is that its molecular structure is similar to that of hemoglobin which is a critical part of human blood. The only exception is their central atom which is iron for hemoglobin and magnesium for chlorophyll. Due to this unique quality, liquid chlorophyll performs the same function in the body as the hemoglobin. Although the world of nutrition is yet to admire the true potential of chlorophyll, it continues to be amongst most critical elements for the plants and the biological world since ages.
