Spermidine first isolated from semen or sperm, is a water-soluble polyamine ingredient that occurs naturally in all tissues of our human bodies and alsofound in many other organisms like animals, plants, and typical dietary foods. Spermidine is able to penetrate biological membranes and believed to be beneficial to cell renewal and anti-aging purposes.Spermidine is a small molecule with a molecular weight of 145.25, and unique CAS Registry Number as 124-20-9. It’s stable at room
temperature. The color of Spermidine-rich wheat germ extract is white to yellowish powder, while for synthetic spermidine powder, the color is white to off-white. Spermidine is also available in the chloride form as spermidine trihydrochloride or spermidine 3 HCL (CAS 334-50-9).
