Poly (delta-L-Orn) is an example of an iso-polypeptide (i.e. variant of the usual poly a-peptide chain), where the a-carboxyl and delta-amino groups of ornithine are used in polymerization while the a-amino groups form the side chain. A procedure for the synthesis of this iso-polypeptide is described. Circular dichroism studies of poly (delta-L-Orn) and its Na-Boc derivative suggest that these polymers might adopt a conformation in solution similar to the beta-pleated sheet.
聚（δ-L-鸟氨酸）是一种异多肽（即通常的聚α-多肽链的变体）的例子，其中鸟氨酸的α-羧基和δ-氨基用于聚合反应，而α-氨基形成侧链。本文描述了这种异多肽的合成方法。聚（δ-L-鸟氨酸）及其Na-Boc衍生物的圆二色性研究表明，这些聚合物在溶液中可能会呈现出类似于β-折叠片的构象。
