Leucine (symbol Leu or L) is an essential amino acid that is used in the biosynthesis of proteins. Leucine is an α-amino acid, meaning it contains an α-amino...

The leucines are primarily the four isomeric amino acids: leucine, isoleucine, tert-leucine (terleucine, pseudoleucine) and norleucine. Being compared...

A leucine zipper (or leucine scissors) is a common three-dimensional structural motif in proteins. They were first described by Landschulz and collaborators...

β-Leucine (beta-leucine) is a beta amino acid and positional isomer of L-leucine which is naturally produced in humans via the metabolism of L-leucine by...

C. Levacetylleucine is a modified version of the amino acid leucine (N-Acetyl-L-Leucine). It is taken by mouth. The most common side effects include...

carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine, and valine. Non-proteinogenic BCAAs include 2-aminoisobutyric...

In enzymology, a leucine transaminase (EC 2.6.1.6) is an enzyme that catalyzes the chemical reaction L-leucine + 2-oxoglutarate ⇌ {\displaystyle \rightleftharpoons...

In enzymology, a leucine dehydrogenase (EC 1.4.1.9) is an enzyme that catalyzes the chemical reaction L-leucine + H2O + NAD+ ⇌ {\displaystyle \rightleftharpoons...

A leucine-rich repeat (LRR) is a protein structural motif that forms an α/β horseshoe fold. It is composed of repeating 20–30 amino acid stretches that...

(N-acetyl-leucine) is a modified leucine amino acid used in the treatment of vertigo and cerebellar ataxia. Two forms exist: acetyl-DL-leucine (sold under...
