Inside our bodies, the B vitamins folate and choline work in a delicate balance.
It is the main functional constituent of the natural surfactants, and the body's foremost reservoir of choline , an essential nutrient.
Betaine is produced in the body by oxidation of choline , another trimethylated, methyl-donating compound.
In spinach and sugar beet the enzymes responsible for converting choline into betaine have been characterized, and the corresponding genes cloned and sequenced.
Found in various forms throughout the body, choline , a member of the vitamin B complex family, is involved in the creation of cell membranes.
