Sea cucumber contains 18 kinds of amino acids, among which glycine, arginine and glutamic acid are much higher than other amino acids. In addition, the essential amino acid content of Stichopus japonicus is significantly higher than that of other sea cucumbers. Amino acids are the material basis for the synthesis of protein, and have extremely high nutritional and medicinal values.
Sea cucumber contains seven vitamins: VA, VB 1, VB2, VB6, VD, VE and VK. Vitamins can't be synthesized by themselves in human body, which is necessary for human growth and metabolism.
The essential fatty acids of sea cucumber are complete, including linoleic acid, linolenic acid, EPA and DHA. The essential fatty acid content of Stichopus japonicus is obviously higher than that of other sea cucumbers. Essential fatty acids play an important role in enhancing human immunity and brain function.
Sea cucumber is rich in essential macroelements and microelements, among which the contents of microelements such as iron and zinc are obviously higher than other elements.
Sea cucumber polysaccharide
Sea cucumber polysaccharide is an important functional component of sea cucumber body wall, and its highest content can account for 365,438+0% of total organic matter in dry sea cucumber. The content and composition of sea cucumber polysaccharide is an important chemical index to measure the nutritional value of sea cucumber. Modern pharmacological research shows that sea cucumber polysaccharide has a variety of pharmacological activities, including anti-tumor, immunomodulation, anticoagulant and antithrombotic, hypolipidemic and so on. Polysaccharides in sea cucumber body wall are mainly divided into chondroitin sulfate and fucoidan sulfate.
Sea cucumber saponin
Sea cucumber saponin is a kind of triterpenoid saponin unique to sea cucumber, which is the main secondary metabolite of sea cucumber and the chemical material basis of its defense. Modern pharmacological activity research shows that sea cucumber saponin has many biological activities such as improving immunity, anti-tumor, anti-bacterial and anti-cancer.
Brain glycoside ester
Brain glycoside, also known as acyl sphingosine hexose glycoside, is an endogenous bioactive substance widely existing in the cell membranes of fungi, plants, animals and marine organisms. Brain glycoside is a kind of sphingolipid, which consists of ceramide and glycosyl. In recent years, 10 kinds of cerebrosides have been reported only in sea cucumber, and it has been found that they have biological activities such as preventing fatty liver and anti-tumor.
ganglioside
Gangliosides are important bioactive components in echinoderms, and their molecules contain one or more sialic acids. Gangliosides are related to many biological processes and play an important role in the pathological process of some central nervous system diseases.
Hundreds of years ago, our people thought that sea cucumber was not only a delicious food, but also a nourishing health product: sea cucumber was warm and nourishing, so it was named sea cucumber; Sweet and salty, tonifying kidney, benefiting essence, resolving phlegm, receiving urine, strengthening yang, treating flaccidity and killing sores. "Modern pharmacological research shows that sea cucumber has a variety of active ingredients and has pharmacological effects such as anti-tumor, immunomodulation and antioxidation.
