Summary
Sulfated galactans (SGs), marine polysaccharides, exhibit conserved structural features across species. Their diverse structures are linked to significant pharmacological potential, particularly as anticoagulants.
Area of Science:
- Marine Biology
- Carbohydrate Chemistry
- Biochemistry
Background:
- Sulfated galactans (SGs) are anionic marine homopolysaccharides primarily composed of galactose.
- Their structures vary across species but share conserved features, including specific sulfation patterns.
- SGs are found in various marine organisms, including algae, invertebrates, and marine plants, serving diverse biological roles.
Purpose of the Study:
- To review the principal structural and functional information of sulfated galactans.
- To highlight the conserved structural features and variations in SGs across different marine taxa.
- To discuss the biological roles and significant pharmacological potential of SGs.
Main Methods:
- Literature review of existing studies on sulfated galactans.
- Analysis of structural data from various marine sources.
- Synthesis of information on biological functions and pharmacological applications.
Main Results:
- Sulfated galactans exhibit conserved structural motifs, such as 3-linked beta-galactoses, with specific sulfation patterns (e.g., 4-sulfation in algae, 2-sulfation in invertebrates).
- These carbohydrates function as extracellular components in cell walls, body walls, and egg jelly coats.
- SGs play roles in biological processes like the acrosome reaction in sea urchins.
Conclusions:
- The structural features of SGs are directly related to their biological and clinical actions, including their efficacy as anticoagulants and antithrombotics.
- The stereospecific interactions between SGs and target proteins underscore their pharmacological relevance.
- Further research into SG occurrence, biology, and phylogeny is warranted to explore their full potential.

01:24Oligosaccharide Assembly
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.

01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:15Cellulose and Pectic Polysaccharides
Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth. Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the parenchyma cells of...

01:05Proteoglycans
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...
01:23Glycosaminoglycans
Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.

01:25Protein Glycosylation
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.
