Bayanin samfur:
L-cysteine , amino acid da aka saba samu a cikin kwayoyin halitta. Yana daya daga cikin sulfur mai dauke da α-amino acid. Yana juya shuɗi (launi saboda SH) a gaban nitroprusside. Ya wanzu a yawancin sunadaran da glutathione. Yana iya samar da mahadi marasa narkewa tare da ions ƙarfe kamar Ag+, Hg+, da Cu+. mercaptide. Wato, RS-M', RSM" -SR (M', M" su ne monovalent da divalent karafa, bi da bi).
Tsarin kwayoyin halitta C3H7NO2S, nauyin kwayoyin 121.16. Lu'ulu'u marasa launi. Mai narkewa a cikin ruwa, acetic acid da ammonia, maras narkewa a cikin ether, acetone, ethyl acetate, benzene, carbon disulfide da carbon tetrachloride. Yana iya zama oxidized zuwa cystine ta iska a tsaka tsaki da kuma rauni alkaline mafita.
