L-Leu-Leu-Leu Chemical Properties,Uses,Production

Description

The tripeptide trileucine (Leu-Leu-Leu) is found in casein and soy protein. This substance could increase the endothelial release of TXB2 which is a stable marker of TXA2. Inhibitor of human liver alanine aminopeptidase, Ki 0.054 mM. The addition of trileucine improved the aerosol performance and stability of spray-dried powders for inhalation.

Chemical Properties

LEU-LEU-LEU is also known Trileucine. It is a white solid powder and soluble in DMSO.

Uses

Leu-Leu-Leu could be used to synthesize Cl-.H2+-Leu-Leu-Leu-OMe (a hydrochloric acid salt of Peptide derivative IIa).
LEU-LEU-LEU

Definition

ChEBI: A tripeptide formed from three L-leucine residues.

storage

Dry, dark and at 0 - 4 C for short term (days to weeks) or -20 C for long term (months to years).
