Marine macro algae, due to their richness in minerals, polysaccharides, vitamins and proteins; can be a suitable source of healthy food. Some of them have been traditionally used, in some special countries, as food items and for medicinal and industrial properties [1]. Determination of their nutrient compounds and findings of bioactive molecules can expand their dietary market as supplements and functional food. The present study was aimed at evaluation of protein content of some algae belong to Persian Gulf and Arabian Sea. Freeze dried samples of 5 species of algae were used for protein extraction. Then the extracted protein was precipitated by TCA. For quantification of proteins, Lowry method was used. The test was repeated for three times [2]. Results and the names of algae are shown in Table 1.

The algae with high protein content can be used as supplements or protein alternatives in dietary food.
