[A comparative study of the content of peripheral and integral proteins in the liver microsomal membranes of vertebrates].

Peripheral and integral protein amounts in liver microsomal membranes of 11 species of vertebrate animals have been investigated. It was found that the peripheral protein content increases in the following sequence: fishes, amphibians, reptiles, birds. The content of integral proteins decreases in the same sequence. The content of proteins in liver membranes from mammals corresponds to that from lower vertebrates.
