Histochemical localization of sialic acids and antimicrobial substances in eccrine glands of porcine snout skin
The distribution of sialic acids and antimicrobial products (lysozyme, IgA, lactoferrin, β-defensin 2) as well as Rab3D in the eccrine glands of porcine snout skin was studied by sialoglycoconjugate histochemistry and immunohistochemistry. The secretory epithelium consisted of two types of secretory cells: dark and clear cells. The dark cells exhibited considerable amounts of sialoglycoconjugat...
متن کاملHistochemical properties of sialic acids and antimicrobial substances in canine anal glands
The functional properties of sialic acids appear to be manifold. Additionally, antimicrobial substances serve as a non-specific defense against microorganisms. In this study, therefore, the localization of sialic acids and antimicrobial substances in the anal glands of dog was studied by sialoglycoconjugate histochemistry and immunohistochemistry. The secretory epithelium, luminal secretions an...
متن کاملThermodynamic Properties of Solutions of Amino Acids and Related Substances
The effect of temperature on the thermodynamic ionization constants of compounds with dipole moments greater than those of the a-amino acids has not heretofore been studied. In this paper results are given for glycylglycine and c-aminocaproic acid, two substances with similar dipole moments. Measurements are also included for aspartic acid, which has recently been studied at 25” in cells withou...
متن کاملTerminology for sialic acids.
We write on behalf of the Nomenclature Committee of the International Union of Biochemistry to comment on the proposal by Scott et al. (1982) to change the name of neuraminic acid to amino-sialosonic acid as a consequence of allotting the name sialose to a hypothetical 3-deoxynonulose. They further propose symbolizing sialose as Sia, sialosonic acid as SiaA, and aminosialosonic acid as SiaNA. W...
متن کاملChemical diversity in the sialic acids and related alpha-keto acids: an evolutionary perspective.
The glycan chains of vertebrate glycoconjugates are composed mostly of fiveand six-carbon sugars. One striking exception is the family of sialic acids (Sia), which are R-keto acids with a nine-carbon backbone. Several other features of sialic acids are unusual. First, they typically occupy the distal end of glycan chains. This “outermost” location makes them suitable for interaction with other ...
