| Popis: |
Despite their evolutionary divergence better than 300 million years ago, insects and vertebrates have evolved many similar mechanisms that promote conservation and maintenance of hormone titers. One prominent feature common to both groups is the presence of plasma or hemolymph binding proteins which transport lipophilic hormones through the circulatory system. In effect, these proteins reduce surface active properties and increase solubility of the bound hormone so that sufficient titers may develop in peripheral tissues. At the target site, the hormone presumably dissociates from the protein, diffuses unaided through the plasma membrane, and binds to receptors within the cell. Thus, the role of the binding proteins in transporting hormones from the synthetic site to distant target cells is essential in the biochemical initiation of physiological events within the organism. |
