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://www.allfixelectricales.shop/product-category/bridge-rectifier-diode/
