Gly-gly-leu is an oligopeptide, and also functions as a plant growth regulator.
ChEBI: Gly-Gly-Leu is a tripeptide composed of glycine, glycine and L-leucine residues joined in sequence. It has a role as a metabolite.
Glycylglycyl-L-leucine was prepared in 98% yield by hydrogenolysis of the protected tripeptide and crystallization of the product from aqueous ethanol. This matarial had [α]24D -28.4° (c, 2 in water), reported [α]20D -28. l° (c, 2.53 in water), [α]26D -28.0°, and [α]19D -29.9° (c, 2 in water)[1].
