Aphanizomenon flos-aquae (dietary supplement) and sun exposure can greatly affect lipid and pigment composition. As more is learned about the components of different cyanobacterial species, growers and harvesters are better able to determine the optimal growth conditions for obtaining optimal yields. " Aphanizomenon flos-aquae" has been shown to contain varying amounts at least 13 vitamins: vitamin A (beta-carotene), vitamin C (ascorbic acid), vitamin E, vitamin K, and many of the B-complex vitamins including B (thiamin), B (riboflavin), B (pyridoxine), choline, biotin, niacin, folic acid, pantothenic acid, and B (cobalamin). However, "Aphanizomenon flos-aquae" contains pseudovitamin B which can block absorbtion of true B and is
Vitamin C -Galactose reacts with the enzyme -galactose dehydrogenase, whereby the lactone ring opens and forms again but with between the carbonyl on C1 and hydroxyl group on the C4, resulting in -galactonolactone. -Galactonolactone then reacts with the mitochondrial flavoenzyme -galactonolactone dehydrogenase. to produce ascorbic acid. -Ascorbic acid has a negative feedback on -galactose dehydrogenase in spinach. Ascorbic acid efflux by embryo of dicots plants is a well-established mechanism of iron reduction, and a step obligatory for iron uptake. All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant
