Biogeochemistry of dissolved free amino acids in marine sediments
Dissolved free amino acids (DFAA) were measured in interstitial water samples squeezed from sediments collected in a variety of depositional environments. These sediments were further characterized by measurements of total organic carbon, total nitrogen, dissolved organic carbon, total hydrolyzable …

Free amino acid composition of flatpea (lathyrus sylvestris L.) as influenced by water-deficit stress, nitrogen fertilization, developmental stage, and rhizobium inoculation
A₂bu composed 20-40% of total free amino acids in flatpea tissues and constituted 2-4% of the tissue dry weight. Higher concentrations of A₂bu were found in the leaves than in the roots. A₂bu concentration in leaves and stems increased slightly with plant age. Higher nitrogen availability increased …
