This editorial outlines the structural features of glycosaminoglycans and proteoglycans. It introduces various types, including intracellular, cell-surface, and extracellular matrix proteoglycans, setting the stage for their pharmaceutical applications.
Area of Science:
- Biochemistry
- Cell Biology
- Pharmacology
Background:
- Glycosaminoglycans (GAGs) and proteoglycans (PGs) are complex carbohydrates crucial for biological processes.
- This editorial introduces the diverse structural characteristics of GAGs and PGs.
Discussion:
- The discussion covers intracellular proteoglycans like serglycin.
- It also details cell-surface proteoglycans, including syndecans and glypicans.
- Extracellular matrix proteoglycans such as aggrecan, perlecan, and small leucine-rich PGs are also described.
Key Insights:
- Common structural features of GAGs are highlighted.
- Key characteristics of various PG classes are presented.
- The editorial serves as an introduction to a special issue on GAGs and PGs.
Outlook:
- The pharmaceutical applications of GAGs and PGs are contextualized within the special issue.
- This work sets the foundation for understanding the therapeutic potential of these molecules.

Glycosaminoglycans
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.

Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
