OCCURRENCE OF AMINO-ACIDS IN MIDDLE-KROL STROMATOLITES FROM NAINITAL,KUMAUN LESSER HIMALAYA

Geochemical studies on Middle-Krol stromatolite sample from Nainital a rea of Kumaun Himalayas revealed the presence of amino acids, viz, cys teine, lysine, aspartic acid, serine, glycine, threonine, alpha-alanin e, proline, valine and phenylalanine with varying amounts of protein b ound (55%) and free amino acids (45%) of the total. Absence of nonprot ein amino acids points to the marked biochemical relationship between Precambrian and extant organisms and their involvement in stromatolite formation.
