Abstract
L-β-phenylalanine was prepared as radioactive iodinated amino acid and purified on a Sephadex G-25 Gel-filtration column. A pH 9.3 buffer was used containing the amino acid glycine. The radioactive amino acid was tested for purity by Ekco scintillation counter and a Carl-Zeiss Spectrophotometer.
Twenty-two normal volunteers aged 20—35 years were given the test dose with a known weight of skimmed cheese and bread. Blood samples were taken at different time intervals and subjected to radioassay. The results were represented on graphs and interpreted in terms of radioactivity considering the balance between absorption and utilization.
