The fragment LQVQLSIR corresponding to the C-terminal globular domain of the murine laminin α1 chain (2722-2729) represents the minimal active sequence of AG-73, an active cell-adhesion peptide. LQVQLSIR could be one of the most important biologically active sites of laminin-1, especially in promotion of the malignant phenotype.

24-Epibrassinolide is a synthetic molecule that has an optical rotation of +19.4° at 20°C. It is also known as H-Leu-Glu-OH and is a product of the reaction between epibatidine and L-glutamic acid. This molecule has been synthesized to study the role of 24-epibrassinolide in photosynthesis, chlorophyll synthesis, and membrane stability. The phosphate group is attached to the amino group on the n-terminal amino acid. 24-Epibrassinolide has an amino acid composition consisting of leucine, glutamate, glutamine, glycine, proline, serine, cysteine, tyrosine, asparagine, histidine and lysine.\n24-Epibrassinolide was first isolated from chloroplasts using refluxing water with ammonium chloride as a solvent. This molecule can be found in nature as well.
