Comparison of plasma sialic acid concentration between retained fetal membrane and healthy Holstein dairy cows
Sialic acid (SA), an acetylated derivative of neuroaminic acid, is widely distributed in mammalian tissues. Since SA is usually bound to glycoproteins, glycolipids, oligosaccharides and polysaccharides, it is scarcely found as free form in the serum. Moreover, SA is an important structural component...
