Studies on the pituitary "fettstoffwechselhormon". VII. Analytical studies on two lipolytically high active peptides from hog pituitary glands.

First results of analytical studies on the highly purified lipolytic active hog pituitary fractions P-LF II C and P-LF II D are reported. Electrophoresis and end-group determinations indicate homogeneity for both peptides. The molecular weights, amino acid compositions, and the N- and C-terminal sequences of these peptides have been established and are compared with the corresponding results of other laboratories. The relation between biological activity and the structure of lipolytic active peptides is discussed.
