PRODUCT INTRODUCTION
description
Cysteamine is an amine that consists of an ethane skeleton substituted with a thiol group at C-1 and an amino group at C-2. It has a role as a radiation protective agent, a human metabolite, a mouse metabolite and a geroprotector. It is an amine and a thiol. It is functionally related to an ethylamine. It is a conjugate base of a cysteaminium.
