Elucidation of the secondary structure of the exchangeable apolipoproteins has been hindered by the difficulty in producing crystals suitable for X-ray spectrographic analyses. Consequently. in order to analyze potential structure-function relationships in the family of insect exchangeable apolipoproteins. apolipophorins-III (apoLps-III). https://countryscenesaddleryandpetsuppliers.shop/product-category/hair-on-cowhide-headstall-and-breast-collar-sets/
