HEMATINS C 205 



which closely resembles the corresponding products from cytochrome c. 

 Consequently, it will be discussed in Chapter VIII in connection with the 

 latter substance. Here it suflfices to note that the linkage: 



CH3 NH., NHj 



I I I 



— CHSCH2CHCOOH or — CH2 — CH2SCH2CHCOOH 



is split by hydrobromic acid, with transformation of the hematin c into 

 hematoporphyrin : 



CH3 NH2 CH3 



11 HBr I HjO 



— CHSCH2CHCOOH ► — CHBr * — CH(OH)CH3
