Area of Science:

• Biochemistry
• Marine Biology
• Immunology

Background:

• Lectins are non-immune, carbohydrate-binding proteins found in various organisms, including marine life.
• Marine organisms produce diverse lectins like rhamnose binding lectins (RBLs), fucose-binding lectins (FTLs), and C-type lectins.
• These lectins possess significant biological and pharmaceutical activities, attracting interest from food, biomedical, and pharmaceutical industries.

Purpose of the Study:

• To cover the characterization, extraction methods, and biofunctionalities of marine lectins.
• To highlight the potential applications of marine lectins in various industries.

Main Methods:

• Extraction typically involves a two-step process using polar salt solutions.
• Purification is commonly achieved through column chromatography.
• Characterization and biofunctionality assessment are key components of the review.

Main Results:

• Marine lectins exhibit diverse carbohydrate-binding specificities.
• They play crucial roles in immune responses, including pathogen recognition and inflammatory reactions.
• Lectins also influence cellular processes like proliferation, protein folding, and molecular trafficking.

Conclusions:

• Marine lectins are a rich source of bioactive compounds with broad applications.
• Standardized extraction and purification methods facilitate their study and utilization.
• Further research into marine lectins will unlock their full potential in biotechnology and medicine.
