Starfish, also known as starfish (commonly known as starfish), belong to invertebrate echinoderms with sea cucumbers and sea urchins, but have different feeding habits. Sea cucumbers often feed on algae in seabed sediments, while starfish mainly prey on some slow-moving marine animals, such as oysters, abalone, sea cucumbers, sea urchins, crabs, scallops, etc., and their vitality is particularly strong.
Starfish are extremely regenerative.
Tear a live starfish into pieces and throw it into the sea, and each piece will soon grow back the lost part, thus growing into several complete new starfish. This amazing regenerative ability makes it a trivial matter to break arms and limbs. Scientists have found that when a starfish is killed by its own kind, it will immediately separate the injured part and run away. At the same time, the reserve cells of the body are activated. These cells contain all the genes of the missing part of the body and cooperate with other tissues and cells to regenerate the missing wrist or other parts. This extremely strong regeneration ability is even worse than sea cucumber.
Starfish has complete nutrients and high content of active substances.
The viscera of starfish is the gonad of starfish, commonly known as starfish yellow, which is rich in protein (15.46%) and fat (10.97%), and contains a certain amount of carbohydrates and minerals. The protein and fat content of starfish yellow is higher than that of sea urchin yellow and sea cucumber. Starfish yellow contains many kinds of amino acids, among which the essential amino acids account for 47.33% of the total amino acids. Among them, the proportion of essential amino acids is reasonable. Starfish yellow is also rich in Tau (taurine, up to 7.5 μ g/mg). Therefore, starfish yellow is a good source of protein. In addition to starfish yellow, starfish shell also contains a variety of amino acids, and the amino acid composition of starfish shell conforms to the composition characteristics of collagen amino acids. Collagen extracted from starfish shells can be used to make sea cucumber substitutes. In particular, starfish yellow contains active zinc that can be directly absorbed by human body, which is a good product for people to supplement zinc and strengthen their health.
The nutritional value of starfish is comparable to that of sea cucumber. ?
Starfish yellow also contains a certain amount of inorganic elements needed by human body, such as copper, iron, magnesium, zinc and so on. The fat of gonad (starfish yellow) also contains eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), accounting for 1 1. 14% and 6.25% of the total fatty acids respectively. In recent years, the research on pharmacological action and clinical application of EPA and DHA shows that EPA and DHA have antithrombotic, hypolipidemic, anti-tumor, anti-inflammatory and immunomodulatory effects, which can significantly reduce the incidence of cardiovascular diseases, so they are called essential fatty acids for human body.
