The Phosphorus-containing Fractions of Sterile Lingcod Muscle During Storage at 0 °C

Abstract
During refrigerator storage of sterile lingcod muscle for up to 3 weeks at 0 °C no significant changes occurred in the P content of the phospholipid, ribonucleic acid, or deoxyribonucleic acid fractions, but in the acid-soluble fraction the portion of total P accounted for by inorganic P increased to 96% from 75%. The P-containing fractions from the fish held in ice for the same period did not differ appreciably from those of the sterile muscle. An aqueous extract of lingcod muscle was shown to be able to form orthophosphate from a variety of phosphorylated compounds.
