Nucleosides and Nucleotides of the Cold Acid-Soluble Portion of the Blood of Steers

Abstract

The ultraviolet absorption spectrum of the cold acid-soluble portion of the blood of steers had a maximum absorption at 297 nanometers. This unusual spectrum was due to the large amount of uric acid riboside that was present. It accounted for over 96% of the material absorbing at 290 nm and for about 50% of the material absorbing at 260 nanometers. Other ultraviolet absorbing compounds present in the acid-soluble fraction were uric acid, AMP, NADP, ADP, uric acid ribotide, ATP, GTP, UTP and unidentified compounds of UDP. Copyright © 1975.
