679ESTIMATION OF ENZYMES [-AMYLASE, PEROXIDASE, ALKALINE PHOSPHATASE, ACID PHOSPHATASE, LACTATE DEHYDROGENASE AND CREATINE KINASE] IN MARINE SEAWEEDS OF MANDABAM SEA COASTThe aim of this study is to characterize the molecular concentration enzymes present in Marine sea weeds. Seaweeds are considered an important source of bioactive molecules. The algal species Gracilaria folifera, Hypenea masiforms (Red) and Sargassum longifolia, Turbinaria gonaidae (Brown) and Bryopsis, Caulerpa peldata (Green) was collected at Rameswaram from the intertidal region at a depth of 1 m during March 2005 in India, enzyme concentration was studied exclusively. Estimation of enzymes such as -amylase, Peroxidase, Alkaline phosphatase and Acid phosphatase was studied for their presence in concentration among sea weeds. Bryopsis reflecting more concentration of Peroxidase, Alkaline phosphatase and Acid phosphatase and Lactate dehydrogenase . Similarly Gracilaria folifera are rich in Alkaline phosphatase.The Sargassum longifolia showing a maximum concentration of Peroxidase, Acid phosphatase and Alkaline phosphatases.a.r.mumtaj@gmail.comResearch6102015Gracilaria folifera,Hypenea masiforms (Red),Sargassum longifolia,Turbinaria gonaidae (Brown),Bryopsis,Caulerpa peldata (Green)S.
