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).
