[Peculiarities in structure and properties of rabbit blood serum and liver albumins in ontogenesis].

Isoelectrofocusing and infrared spectroscopy were used to study blood serum and liver albumins in rats aged 30, 45, 90 days, 6 months and 2 years. The analysis of infrared and isoelectric spectra shows that the blood serum albumin as compared to the liver albumin is more basic albumin with a less hard structure. With age theses albumins are found to become similar. An assumption is advanced that a modified albumin participates in the processes of this albumin decay and synthesis.
