1972), and Carpinelli and Malaisse (1981), L-Leucine
induces insulin secretion by two mechanisms: (i) enhanced mitochondrial metabolic activity through activation of glutamate dehydrogenase, and (ii) by transamination to [alpha]-ketoisocaproate and subsequent entry into the TCA cycle via acetyl-CoA leading to an increase in ATP production.
is an essential amino acid that promotes muscle synthesis.
The objective of this study was to assess the effect of L-leucine
supplementation on carcass composition and sensory characteristics in grower-finisher broilers fed different levels of CP.

It has higher concentrations of the essential branched chain amino acids L-isoleucine, L-leucine
and L-valine, and is also a rich source of the powerful microfractions alpha-lactalbumin and glycomacropeptides, which are key factors in enhancing bioavailability, boosting immune response and greatly increasing anabolic activity.

Isovaleric acidemia (IVA) is a rare inborn error of L-leucine
catabolism, caused by deficiency of isovaleryl coenzyme A dehydrogenase.
