The seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen. [5]
The compound is usually available as the monohydrate, a white, odorless, crystalline powder. The solid contains separate sodium cations Na+ and glutamate anions in zwitterionic form, − OOC-CH (NH+3)- (CH2) 2 -COO −. [ 38 ] In solution it dissociates into glutamate and sodium ions.
