In plants, natural phytic acid (phyti cacid) hardly exists in free form, but in the form of phytate. This is the brilliance of plants – phytic acid uses six phosphate groups in its molecule to store phosphorus. Preserve all kinds of nutrients in it, and release them as nutrients for sprouts after germination and activation in the next year.
Therefore, when it comes to phytic acid in plants, it generally refers not only to free phytic acid itself, but also to phytate. These phytates are compound salts (with several metal ions) or single salts (with one metal ion) formed by combining phytic acid with calcium, magnesium, potassium, sodium, iron and other metal ions. It is mainly in the form of calcium magnesium double salt, that is, calcium magnesium phytate, commonly known as phytin.
