Содержание глицина, аланина и пролина в некоторых биологических объектах

Abstract

В результате проведенных исследований установлено, что в лекарственных растениях (спирулина, эхинацея и родиола розовая) и казеине молока уровни пролина и аланина превышали содержание глицина. = The studies found out that in medicinal plants (Spirulina, Echinacea, and Rhodiola rosea) and milk casein levels of proline and alanine exceeded glycine content. The total content of the three small amino acids in the protein standard for analysis, casein, were within 41,4–43,7 mmol/l. In Echinacea the total content of the three amino acids was 14% higher than in the casein due to the high content of proline. The content of the three amino acids in Spirulina and Rhodiola rosea is lower than in casein, but the content of Spirulina alanine is 41% more than in casein. In the composition of proteins of Rhodiola rosea contains 3 times more glycine than casein. Compared to casein in the hemolymph of the oak silkworm pupae the content of proline is 4 times lower, but levels of glycine are 4,8 times higher, the content of alanine being the same. In rat blood plasma content of the amount of proline, glycine and alanine is 19 times less than in the hemolymph of oak silkworm pupae. In the liver of rats the content of glycine is 3,8 times higher, alanine – 1,8 times higher, but the level of proline in comparison with the heart is 2,2 times lower. In the epiphysis, midbrain, and hypothalamus of rat brain glycine content exceeds the level of alanine 2,44, 2,63 and 1,61 times, respectively. In lymphocytes of liver, thymus and spleen the content of proline and alanine exceeded the glycine content.
