15 صفحه اولAn improved method for the determination of pantothenic acid in tissues.
During work on coenzyme A (CoA), a method for the liberation of pantothenic acid from the coenzyme was worked out (1). The method involves the use of a combination of two enzymes; namely, intestinal phosphatase and an enzyme extractable from acetone powder of bird liver (chicken (2), duck, or pigeon). This procedure proved the most efficient pretreatment to liberate bound vitamin under conditio...
