H-LEU-LEU-OH Chemical Properties,Usage,Production

Chemical Properties

White powder

Uses

Leu-Leu-OH (L-Leucyl-L-leucine), a Leu derivative, is a neutral dipeptide that can be used to study the functionality of dileucine motifs[1].

Definition

ChEBI: A dipeptide formed from two L-leucine residues.

Biological Activity

Leucylleucine (Leu-Leu) may be used to study the functionality of dileucine motifs such as the motif responsible for internalization and targeting of vesicular acetylcholine transporter and clathrin adaptors AP-1 and AP-2.
