Photosynthetic Action Spectra of Marine Algae
A polarographic oxygen determination, with tissue in direct contact with a stationary platinum electrode, has been used to measure the photosynthetic response of marine algae. These were exposed to monochromatic light, of equal energy, at some 35 points through the visible spectrum (derived from a monochromator). Ulva and Monostroma (green algae) show action spectra which correspond very closel...
متن کاملThe Effects of Marine Algae on Osteoporosis
Background: Osteoporosis is a prevalent bone disease caused by an imbalance between bone formation and resorption. Nutritional factors are involved in the prevention of osteoporosis. Several treatments exist for osteoporosis including bisphosphonates, parathyroid hormone, estrogen therapy, and hormone therapy, which have their own side effects. In the quest for an appropriate treatment for os...
متن کاملThe marine algae of the Sistan and Baluchestan Province, Iran
The identification of marine algae in the Sistan and Baluchestan Province were performed from December 1998 to November 1999 at the coastal area of Gwatr (25 10´ N; 61 30´ E) and Mydani (25 24´ N; 59 5´ E). Data on vegetation were gathered in subtidal and intertidal zones by seasonal and monthly sampling, respectively. Samples were transferred to the laboratory and fixed...
متن کاملAlkaloids in Marine Algae
This paper presents the alkaloids found in green, brown and red marine algae. Algal chemistry has interested many researchers in order to develop new drugs, as algae include compounds with functional groups which are characteristic from this particular source. Among these compounds, alkaloids present special interest because of their pharmacological activities. Alkaloid chemistry has been widel...
