L Leucine Environmental Fate & Ecotoxicity
Identifiers
Functions
What is the environmental fate of L leucine?
Transport, degradation, persistence and exposure pathways
Natural Pollution Origins
Leucine is one of the nine indispensable amino acids that cannot be synthesized to meet body needs in animals and therefore must be provided in the diet(1)
L-Leucine is an essential branched-chain aliphatic amino acid found in many proteins. It is an isomer of leucine. It is important in hemoglobin synthesis and regulation of blood sugar and energy levels(1). /L-Leucine/
D-Leucine is an essential branched-chain amino acid important for hemoglobin formation(1). /D-Leucine/
Probable Routes of Human Exposure
NIOSH (NOES Survey 1981-1983) has statistically estimated that 21,979 workers (16,153 of these were female) were potentially exposed to leucine in the US(1)
Where has L leucine been measured in the environment?
Measured occurrences across water, soil, sediment, air and effluent
