Edestin, (also known as Edistin) is a highly-digestible, hexameric legumin protein with six subunits, and a seed storage protein, with a molecular weight of 310 kDa. This protein is primarily found in hemp seeds. Edestin is a

Edestin can also be broken down to edestan.


Hemp seed

It has been discovered that there are seven cDNAs encoding edestin in Cannabis sativa L., the sequences are distinguished by globulin characteristic. There is a type 1 and type 2 of edestin that are both used in process of the development of hemp seeds. Edestin has been used to help the nutritional quality of plant consumption.  Hemp seeds are considered to be fruits from hemp plants, and can be used in several different methods: medicine, food, fiber, or psychoactive adjuvants.
