Amino Acid, Protein, and Caloric Content of Vascular Aquatic Macrophytes

Abstract

The percentage of each amino acid in the total protein was remarkably similar in 11 species of vascular aquatic plants, as well as in the same species from different sites and the same species at different stages of maturity. Total protein concentrations in the various samples differed greatly, however; such differences may have great importance in food webs. Caloric values for all samples were relatively uniform.
