1. What is vegetal chitosan?

Chitosan is a natural biopolymer that is primarily derived from chitin, which is the second most abundant natural polysaccharide after cellulose. Chitin is commonly found in the exoskeletons of crustaceans like crabs, shrimps, and lobsters, as well as in the cell walls of certain fungi like mushroom, aspergillus niger.

Structure and Properties:

• Chemical Structure: Chitosan is obtained by deacetylating chitin. This process involves removing acetyl groups from chitin, resulting in a polymer that has free amine groups.
• Solubility: Unlike chitin, chitosan is soluble in acidic to neutral solutions, making it more versatile for various applications.
• Biocompatibility and Biodegradability: Chitosan is known for its excellent biocompatibility and biodegradability. It’s non-toxic and can be broken down by natural biological processes.

Chitosan, sometimes known as deacetylated chitin, is a natural polycationic linear polysaccharide derived from partial deacetylation of chitin. Chitin is the structural element in the exoskeleton of insects, crustaceans (mainly shrimps and crabs shell), and cell walls of fungi (oyster mushroom, agaricus bisprous and aspergillus niger), and also is the second most abundant natural polysaccharide after cellulose.

Chitosan, a natural polysaccharide prepared of fungal origin, is initially extracted and purified from reliable and abundant food or biotechnological fungal sources such as Agaricus bisporus or Aspergillus niger.

Chitosan is composed of glucosamine sugar units (deacetylated units) and N-acetyl-D-glucosamine units (acetylated units) interconnected by ß→(1.4) type linkages.

Uses and Applications:

1. Medical and Pharmaceutical Fields: Due to its biocompatibility and non-toxic nature, chitosan is used in wound healing, drug delivery systems, and as a biomaterial in tissue engineering.
2. Water Treatment: Its ability to bind with heavy metals and other contaminants makes it useful in water purification and treatment processes.
3. Agriculture: As a natural biostimulant and elicitor, chitosan is used to enhance plant growth and provide resistance against pathogens.
4. Food Industry: It’s used as a food additive for its antimicrobial properties, and as an edible film or coating to enhance the shelf life of perishable food products.
5. Cosmetics and Personal Care: In this realm, it finds use as a thickener, moisturizer, and film-forming agent, particularly in hair and skin care products.

Chitosan has been widely used in various fields, including wine, pharmaceuticals, dietary supplement, medicine, agriculture, and food industries, due to its biocompatibility, biodegradability, and non-toxicity. In recent years, researchers have investigated the use of vegetal chitosan, which is derived from fungal or plant sources, as a sustainable alternative for use in wine applications.

Variants:

However, in terms of market dominance for the specific application of weight loss through fat binding, acid-soluble chitosan in capsule form remains highly popular.

7. What is the working mechanism of vegetal chitosan in weight-loss?

Vegetal chitosan works through several mechanisms to aid in weight loss, primarily by interacting with dietary fats and affecting metabolic processes. Here’s a detailed look at how vegetal chitosan functions:

1. Fat Binding: The primary mechanism through which vegetal chitosan aids in weight loss is by binding to fats in the stomach. Chitosan is a positively charged polymer, and since fats (lipids) are negatively charged at stomach pH levels, chitosan can effectively bind to them. This binding creates large complexes of fat and chitosan that the body cannot absorb. As a result, these complexes are excreted rather than digested, leading to a reduction in the total caloric intake from fats.
2. Reduction of Fat Absorption: By binding with dietary fats, vegetal chitosan reduces the amount of fat absorbed by the intestines. Less fat absorption can contribute to a caloric deficit, which is essential for weight loss.
3. Appetite Suppression: There is evidence to suggest that chitosan might help reduce appetite. This effect could be due to the increase in the viscosity of stomach contents after chitosan binds to fats, which may slow digestion and extend feelings of fullness. This delayed gastric emptying can lead to reduced overall food intake.
4. Potential Impact on Cholesterol: Chitosan is also known to bind to bile acids or cholesterol, which might help lower blood cholesterol levels. Lower cholesterol can contribute to overall better health and support metabolic processes that are conducive to weight loss.
5. Improved Gastrointestinal Health: As a form of dietary fiber, chitosan can help improve gastrointestinal function. A healthy digestive system is crucial for effective metabolism and can assist in weight management by improving nutrient absorption and maintaining regular bowel movements.
6. Blood Sugar Regulation: Some studies indicate that chitosan might help stabilize blood sugar levels by reducing the absorption rate of sugars in the intestine. Stable blood sugar levels can help prevent insulin spikes that lead to fat storage, thus supporting weight loss efforts.

These diverse mechanisms make vegetal chitosan a multi-functional agent in weight loss supplements, capable of affecting both the intake and digestion of dietary fats, as well as influencing overall metabolic health.

8. Is chitosan Effective and safe gene-based delivery of GLP-1 that is current very popular medicine for obesity?

Based on the study research: https://pubmed.ncbi.nlm.nih.gov/21412280/, it focuses on the development and characterization of a chitosan-based nanoparticle for the delivery of GLP-1 (glucagon-like peptide-1) gene therapy. GLP-1 is a hormone involved in glucose regulation and appetite control, making it a promising target for treating obesity. This research explores the potential of chitosan as a carrier for gene therapy aimed at enhancing the body’s production of GLP-1, which could theoretically aid in weight loss and improve glucose homeostasis.

Effectiveness of Chitosan in Gene Delivery:

Chitosan’s natural properties make it an attractive candidate for gene delivery systems:

• Biocompatibility: Chitosan is biocompatible, meaning it’s generally safe to use within the body and does not typically provoke an immune response.
• Biodegradability: It breaks down into natural components in the body, reducing long-term toxicity risks.
• Enhanced Delivery: Its positive charge allows it to form stable complexes with negatively charged molecules like DNA or RNA, which can be beneficial for delivering genetic material into cells.

The specific study on the chitosan-based delivery system for the GLP-1 gene shows that this approach could potentially enhance the therapeutic effects of GLP-1, such as improved blood glucose control and reduced appetite, both key components in managing obesity.

Safety of Chitosan in Gene Delivery:

While chitosan is generally considered safe and has been used in various biomedical applications, the safety of a chitosan-based gene delivery system specifically for delivering the GLP-1 gene would need thorough evaluation in clinical trials. Here are a few considerations:

• Immunogenicity and Inflammatory Response: While chitosan is typically biocompatible, any gene therapy application needs to monitor for potential immune reactions or inflammation.
• Long-term Effects: The long-term effects of gene therapy, including potential off-target effects and the stability of gene expression, would need careful study.
• Regulation and Approval: Any gene therapy approach, particularly for treating common conditions like obesity, would require rigorous clinical testing and regulatory approval to confirm its efficacy and safety.

Conclusion:

Based on the properties of chitosan and the preliminary research into its use for GLP-1 gene delivery, there is potential for this approach in treating obesity. However, whether this is effective and safe for widespread clinical use will depend on the outcomes of detailed clinical trials designed to rigorously evaluate its therapeutic benefits and potential risks. The concept is promising, but more research is necessary to move from experimental stages to practical medical applications.
