Professor Williams and his associate, Paul Charles Zamecnik, Harvard associate in medicine, have a serious purpose. They are trying to study the structure of protein, the basic substance of living creatures. Fibroin, the principal constituent of silk, is a protein. Scientists know that it is made of certain amino acid molecules linked together in chains. What they do not know is how the chains are put together. The plan is to find out how the silkworms do it. Professor Williams is injecting mature worms with various amino acids which are made radioactive by carbon 14. After a while the worms...
...Alamine. A radioactive isotope of carbon has carried three doctors from Boston's Huntington Hospital a little farther toward showing just how cancer cells and normal cells differ. Drs. P. C. Zamecnik, I. D. Frantz Jr., and R. B. Loftfield tagged a protein-building amino acid called l-alzmine with the isotope, watched what cancer tissue and normal liver tissue did with it in test tubes. They found that cancerous livers absorbed the amino acid much faster than normal livers. Eventually, their experiments might help explain why cancer cells grow disastrously faster than normal cells...
