Polyprotic Acid Titrations. Polyprotic acids, also 2020년 7월 27일 Structures and predominant types of sialic acids. Left panel: sialic acids (Sia) are often terminating units of N- and O-linked glycoproteins and Sialic acids comprise a family of about 40 derivatives of the nine-carbon sugar neuraminic acid.

Sialic acid

'Sialic acid'is the generic namegiven to a family ofcompounds derived from the 9-carbonsugar neuraminic acid. By far the major derivative in human tissues is N-acetylneuraminic acid (NANA). Other sialic acids contain a range of substituents, singly or in combination, in the positions indicated (Fig. 1). Sialic acids are terminal sugar components of Characteristics of sialic acid Sialic acid is a generic term for a variety of molecules with the common feature of a nine-carbon skeleton. The most prevalent form is the N-Acetylneuraminic acid, Neu5Ac, and is the one most often referred to in literature.

Porcine transmissible gastroenteritis virus (TGEV) has been shown to agglutinate erythrocytes using α2,3-linked sialic acid on the cell surface as binding site.

Sialic acid determination in a complex matrix, such as a dairy product, presents many challenges. The majority of milk sialic acids are found as part of a glycoconjugate rather than as the free acid. In human milk, ~73% of sialic acid is bound to oligosaccharides, but infant formulas have been shown to contain sialic acids primarily bound Sialic Acids (neuraminic acids) are usually found as terminal structures of both N-linked and O-linked glycans. Being located at the terminal position of glycans, sialic acids are a likely point of contact for many glycoprotein interactions.

The term "sialic acid" was first introduced by Swedish biochemist Gunnar Blix in 1952. The most common member of this group is N-acetylneuraminic acid found in animals and some prokaryotes. Sialic acids are found widely distributed in animal tissues and related forms are found to a lesser extent in other organisms like in some micro-algae, bacteria and archaea.

Sialic acid as a raw material can develop a series of essential sugar drugs, anti-virus, anti-tumor, anti-inflammatory, treatment of senile dementia have outstanding results.

The chemical structure of sialic acid, which features an anomeric center with carboxyl and methylene substituents, poses a challenge for synthesis of the α-glycoside, thus impeding biological and therapeutic studies on sialic acid–containing glycans.

P Khalili, J Preferentially binds to alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface.
