Abstract
PHYSICOCHEMICAL work shows that ionizing radiations cause fragmentation and aggregation of protein molecules1–3. When protein molecules are degraded there is a variety of products and also many amino-acids are degraded. However, the mechanisms by which these changes occur are still obscure. In our experiments, we define the radiation damage to cyto-chrome c, hæmoglobin, catalase, and egg albumin in terms of radiation-lability of amino-acids and loss of biological properties of the three hæmoproteins. The amino-acid pattern of scission products and insoluble protein aggregates was also determined.
