Polarographic Examination of Sialic Acids

Nature, 1961
WE have investigated systematically the polarographic wave of neuraminic acid derivatives with a dropping-mercury electrode (m = 2.86 mgm./sec., t = 2.98 sec.). The existence of a sialic acid wave was anticipated from the fact that structurally related substances such as pyruvic acid1,2 and fructose3,4 give well-defined polarographic waves.

Metabolism of Sialic Acids [PDF]

, 1982
The wide occurrence of sialic acids in nature is an indication of their great biological importance. As is described in other chapters in this book, the identification of the sialic acids was pioneered in several laboratories, while the biosynthetic mechanism of sialic acid formation was elucidated essentially by the work of Roseman’s and Warren’s ...

The distribution of sialic acids in nature

Comparative Biochemistry and Physiology, 1963
Abstract 1. 1. The occurrence of sialic acids acids in nature has been studied. These acids are found in all species of Vertebrata, Cephalochorda, Hemichorda and Echinoderma tested. 2. 2. They are distributed sporadically in the phyla Platyhelminthes, Mollusca, Anthropoda and in bacteria.

Occurrence of Sialic Acids

1982
The discovery and the widespread occurrence of the sialic acids in mammalian tissues (Blix 1936, Klenk 1941) has been correlated with a range of different biological functions (see chapter J) which continues to expand. Although the literature on sialic acid occurrence is large (Gottschalk 1960, Blix and Jeanloz 1969, Tuppy and Gottschalk 1972, Schauer ...

Histochemistry of Sialic Acids

1982
The aim of this chapter will be to escort the reader through the maze of histochemical methodology available for the location and identification of sialic acids and their variants in tissue sections. We shall confine most of our discussion to those forms of sialic acid which can be demonstrated histochemically, the methodology by which they may be ...

Sialic acid and mucus rheology

Clinica Chimica Acta, 1981
Mucus glycoproteins are high-molecular-mass proteins with many hundreds of oligosaccharide units. Each unit contains about S10 monosaccharide residues. Sialic acid is located at the terminals on carbohydrate chains. In humans sialic acid is represented by N-acetylneuraminic acid (NANA), but other sialic acids such as N-glycollylneuraminic acid or O ...

The enzymes of sialic acid biosynthesis

Bioorganic Chemistry, 2005
The sialic acids are a family of nine carbon alpha-keto acids that play a wide variety of biological roles in nature. In mammals, they are found at the distal ends of cell surface glycoconjugates, and thus are major determinants of cellular recognition and adhesion events.
