[Preliminary study of 3 algae of the Ulvaceae family from the Mãe Luisa beach (RN)].
Samples of marine algae from Brazilian coast were analysed for the proximate composition, calcium, phosphorus, iron and aminoacids. Ulva fasciata, Enteromorpha intestinalis and Enteromorpha flexuosa have been studied, specimens being collected at "Mãe Luisa" beach in the State of Rio Grande do Norte, between the months of September and November 1973. Quantitative determinations of the aminoacid composition of each were made and a comparison of the results pointed to the similarity of composition of all species examined. Limiting aminoacids were methionine, lysine, isoleucine, tryptophan and cystine, except for Enteromorpha intestinalis and Enteromorpha flexuosa, in which triptophan and cystine, respectively, were not limiting.
