Pig S-Parotin (2)

Abstract

The hog S-parotin gave elementary analytical values of 45.85% carbon, 7.40% hydrogen, and 14.33% nitrogen, and was positive to almost all of the general protein reaction. Its componental amino acids were 17 kinds, same as in parotin, and contained valine which was not present in the bovine and equine S-parotin. Polarography of the hog S-parotin showed a half-wave potential by the second wave of bivalent cobalt of -1.35 V. This S-parotin did not affect the inorganic phosphorus level in rabbit serum.
