spermidine

Spermidine is a polyamine compound (C7H19N3) found in ribosomes and living tissues, and having various metabolic functions within organisms. It was originally isolated from semen.

Spermidine is an aliphatic polyamine. Spermidine synthase (SPDS) catalyzes its formation from putrescine. It is a precursor to other polyamines, such as spermine and its structural isomer thermospermine.

Spermidine synchronizes an array of biological processes (such as Ca2+, Na+, K+ -ATPase) thus maintaining membrane potential ...
