Annex 1. Essential amino acid (EAA) composition of aquatic macrophytes

The EAA of some aquatic macrophytes is provided in Table 1. Further information on the EAA composition of Azolla and on duckweed is contained in Table 2 and Table 3 respectively.

Table 1
Essential amino acid composition of some aquatic macrophytes

Arg = Arginine; Hist = Histidine; I so = I soleucine; Leu = Leucine; Lys = Lysine; Met = Methionine; Phen = Phenylalanine; Thr = Threonine; Tryp = Tryptophan; Val = Valine; Tyr = Tyrosine) n.s. = not stated.
*Values expressed as percent DM basis.

Table 2

1 Arg = Arginine; Hist = Histidine; Iso = Isoleucine; Leu = Leucine; Lys = Lysine; Met = Methionine; Phen = Phenylalanine; Thr = Threonine; Val = Valine; Cys = Cysteine; Tyr = Tyrosine); crude protein levels not stated
