Definition and classification of polysaccharides
What is a polysaccharide?
Polysaccharides are carbohydrate polymers monosaccharide units (saccharides) linked together by sugar bonds . Unlike monosaccharides (such as glucose) and disaccharides (such as sucrose), which are simple or short-chain sugars, polysaccharides are complex carbohydrates forming long and often branched structures.
These molecules can be composed of tens to several thousand sugar units, giving polysaccharides specific properties , such as water retention, viscosity and gel formation.
There are two main categories of polysaccharides:
- Homopolysaccharides , consisting of a single type of monosaccharide. Examples: starch and cellulose (composed only of glucose).
- Heteropolysaccharides , which contain several types of monosaccharides. Examples: hemicelluloses and glycosaminoglycans. Pectins, rich in galacturonic acid , are particularly used in the food industry for their gelling and thickening properties .
Polysaccharides perform different biological functions depending on their structure and degree of branching. Some are digestible (starch, glycogen), while others are not and act as dietary fiber (cellulose, pectin).
Among them, beta-glucans are particularly studied for their immunomodulatory properties and their beneficial role on cardiovascular health.
The main categories of polysaccharides
Reserve polysaccharides
Storage polysaccharides are used by living organisms to store energy in the form of complex carbohydrates . They can be rapidly broken down into glucose units when the body needs energy.
- Starch : It is the main carbohydrate reserve of plants. Present in cereals (wheat, rice, corn), tubers (potatoes) and legumes, it is composed of two main fractions:
- Amylose : linear structure facilitating compact storage.
- Amylopectin : branched structure that allows rapid release of glucose.
- Glycogen : It is the equivalent of starch in animals and fungi. Stored mainly in the liver and muscles , it can be quickly mobilized to provide energy when needed.
Structural polysaccharides
These polysaccharides have an essential function in the structure and rigidity of plant, fungal and animal cells .
- Cellulose most abundant polysaccharide . Present in the wall of plant cells, it gives plants their rigidity and mechanical resistance. It is made up of linear chains of glucose linked by β(1 → 4) , which makes it indigestible for humans but essential in the diet as a dietary fiber .
- Chitin : Present in the shell of arthropods (crustaceans, insects) and the cell wall of fungi , chitin is a nitrogenous providing protection and strength.
Functional and specific polysaccharides
Certain polysaccharides have particular properties which make them of interest in the medical, cosmetic and agri-food fields.
- Glycosaminoglycans (GAGs) negatively charged polysaccharides play a key role in connective tissue and joint lubrication . These include hyaluronic acid (used in cosmetics and medicine for its moisturizing and anti-aging properties), as well as chondroitin and dermatan sulfate .
- Alginates, carrageenans and agar-agar : These polysaccharides of marine origin, extracted from brown and red algae, are used as thickeners and gelling agents in the food and cosmetics industries.
- Beta-glucans : Present in cereals (oats, barley), mushrooms and certain yeasts, they are studied for their immunomodulatory effects and their role in reducing blood cholesterol .
Structure and physicochemical properties
Solubility and hydrophilicity
Polysaccharides have a high capacity to interact with water . Some, such as pectins and vegetable gums , are highly soluble and can form gels used as food thickeners (e.g., jams, sauces).
Others, such as cellulose , are insoluble and form rigid fibers that facilitate intestinal transit and provide a feeling of satiety.
Gel formation and viscosity
Some polysaccharides, when dissolved in water, form viscous or gel-like , depending on their concentration and molecular structure.
- Starches and pectins are responsible for the thick texture of many food products.
- Carrageenans and alginates are used to stabilize and structure dairy products, sauces and cosmetics.
Chemical properties and biodegradability
- Polysaccharides are biodegradable and play a major ecological role as a renewable resource .
- Their enzymatic degradation allows their assimilation by the organism or their natural recycling in ecosystems.
These properties explain their importance in sectors such as food, medicine, bioplastics and pharmacology .
This first section lays the foundations for understanding polysaccharides, detailing their structure, classification, and key characteristics. The following sections will cover their food sources, their impact on health, and laboratory analytical methods.
