Distribution of free N-acetylneuraminic acid in rat organs.
The concentration of free N-acetylneuraminic acid in various rat organs was estimated by gas chromatography/mass spectrometry. Its concentration was in the range of 3.95 to 104.72 micrograms/g wet tissues, being particularly high in the endocrine glands. The ratio of free N-acetylneuraminic acid to total N-acetylneuraminic acid varied from 0.031 to 0.183, being especially high in the adrenal gland (0.181) and heart (0.183).
