list down the constituents of Sulphur containing compound in lithosphere, hydrosphere, atmosphere and in living organisms.
1 SOME TIMES FOUND IN PURE FORM BUT SULPHUR ON EARTH USUALLY OCCUR AS SULPHIDE AND SULPHATE MINERALS
suphur present in in igneous rocks and sedementary rocks .sulphur in lithosphere mobilised by slow weathering which produces h2s gas .it is found in the form of pyrite or iron sulphide
2 in hydrosphere found as gypsom -CaSO4.2H2O
polyhalite K2Ca2Mg(SO4).2H2O
glaserite K6Na2O16S4
kieserite MgSO4.(H2O)
kainite ClH6KMgO7S
langbeinite K2Mg2(SO4)3
3 IN ATMOSPHERE VOLCANIC EMISSION OF SO2
HYDROGEN SULPHIDE
,DIMETHYLE SULPHIDE
,CARBONYL SULPHIDE
,AND CARBONDISULPHIDE ARE THE MAJOR SULPHUR COMPOUNDS IN ATMOSPHERE
4 LIVING ORGANISM SULPHUR PRESENT IN AMINOACIDS
METHIONINE CHEMICAL FORMULA C5H11NO2S
,CYSTEINE MADE BY TRANSMETHYLATION PATHWAY OF METHIONINE C3H7NO2S
AND CYSTINE
VITAMINS
BIOTIN AND THIAMIN BIOTIN HAVING A VALERIC ACID SUBSTITUENT ATTACHED TO TETRAHYDROTHIOPHENE RING THIAMINE HAS 5 PHOSPHATE DERIVATIVES
IN CO FACTORS GLUTATHION ,THIERDOXIN
IN PROTEIN KERATIN WHICH CONSTITUTES SKIN AND HAIR OF ANIMALS
