Abstract
Ile-Ala-Val-Pro as a hypocholesterolemic peptide was isolated from soybean protein. We have synthesized four peptides, Ile-Ala-Val-Pro-Gly-Glu-Val-Ala, Leu-Ile-Ala-Val-Pro-Gly-Glu-Val-Ala, Ile-Ala-Val-Pro-Thr-Gly-Val-Ala, Leu-Ile-Ala-Val-Pro-Thr-Gly-Val-Ala, with a conserved Ile-Ala-Val-Pro amino acid sequence, for circular dichroism investigations. These four peptide sequences were also found in the amino acid sequence in soybean protein, which was defined from the genomic sequence. Additionally for a detailed analysis of conformation features of these peptides, the Ile-Ala-Val-Pro and Leu-Ile-Ala-Val-Pro were also synthesized. All peptides were prepared using standard fluorenylmethyloxycarbonyl methodology and the peptide yields ranged from 90 to 95% of the theoretical yields with purity after purification above 99%.
