A review on shellfish polysaccharides: Extraction, characterization and amelioration of metabolic syndrome

Abstract

Shellfish are diverse, widely distributed organisms that are a rich source of biological resources. Polysaccharides are an important components in shellfish, hence a great deal of attention has been directed at isolation and characterization of shellfish polysaccharides because of their numerous health benefits. Differences in shellfish species, habits, and environment result in the diversity of the structure and composition of polysaccharides. Thus, shellfish polysaccharides possess special biological activities. Studies have shown that shellfish polysaccharides exert biological activities, including antioxidant, antitumor, immune-regulation, hypolipidemic, antihypertensive, and antihyperglycemic effects, and are widely used in cosmetics, health products, and medicine. This review spotlights the extraction and purification methods of shellfish polysaccharides and analyses their structures, biological activities and conformational relationships; discusses the regulatory mechanism of shellfish polysaccharides on hyperlipidemia, hypertension, and hyperglycemia caused by lipid metabolism disorders; and summarizes its alleviation of lipid metabolism-related diseases. This review provides a reference for the in-depth development and utilization of shellfish polysaccharides as a functional food to regulate lipid metabolism-related diseases. To achieve high value utilization of marine shellfish resources while actively promoting the development of marine biological industry and health industry.

Morphological Trait Correlations, Gonadal Development Characteristics and Pleopod Nutrient Compositions of the Whelk Volutharpa perryi perryi

“…Moreover, monosaccharides can also give the food a sweet taste, making the food taste better [67][68][69]. Therefore, the type and content of monosaccharides are also one of the important indicators to evaluate the nutritional or medical value of the commercial traits of shellfish [70][71][72][73]. In this study, a total of eight kinds of monosaccharides were detected in the pleopods of the whelk, more than in Bullacta exarata (6) [74], H. discus hannai (4) [75], and N. didyma (6) [76].…”

The Relationship between Preparation and Biological Activities of Animal-Derived Polysaccharides: A Comprehensive Review

“…In recent years, investigations on the bioactivities of animal polysaccharides have been emerging, and the following have been unearthed: hypoglycemic [ 73 ], hypolipidemic [ 74 ], anticoagulant [ 75 ], antiviral [ 76 ], and immunoregulatory activities ( Figure 2 ). Within the life sciences field, we are committed to finding natural products with excellent biodegradability and compatibility, and polysaccharides are one of the representative substances [ 1 ].…”

“…Shellfish synthesize and accumulate numerous structurally novel and functionally unique active substances, such as polysaccharide compounds. [ 10 ] Compared to polysaccharides found in terrestrial plants and animals, those in shellfish generally exhibit higher solubility, thus facilitating the development of formulations. [ 11 ] Shellfish products rich in acidic polysaccharides have been shown to exhibit various biological activities such as liver protection, hypolipidemic, hypoglycemic, hypotensive, anti‐inflammatory, anticoagulant, antitumor, and antioxidant effects.…”
