Uses & manufacturing
General Manufacturing InformationLaminaran: ACTIVE
Applications
DescriptionLaminarin mainly includes brown algae (such as sodium alginate, also known as alginate, the content in kelp is about 19.7%), fucoidan (also known as laminarin, seaweed sulfate polysaccharide, fucoidan, the content in kelp is about 1%), Fucoidan (also known as fucoidan, the main component is fucoidan, also known as fucoidan) and other 3 types, consisting of β(1-3)-glucan and some β(1-6)- Composed of glycosidic bonds, it is a kind of neutral glucan, widely present in brown algae, and also the main chemical component in kelp of the family Pterophyceaceae or kelp of the kelp family. It has the functions of regulating immunity, anti-tumor, anti-coagulation, regulating blood lipids. , hypoglycemic, anti-radiation, antioxidant, antibacterial, antiviral and other pharmacological effects, but also has various effects such as lowering blood pressure, fatigue resistance, anti-pulmonary fibrosis, regulating tyrosine kinase activity, and anti-mutation.
OccurrenceKombu, also known as kelp, seaweed, sea kelp, sea cabbage. Extracted from the thallus of Laminaria japonica Aresch. and Ecklonia kurome Okam.
UsesLaminarin is a storage glucan and is now used to study its interaction with laminarinase as its substrate.
General DescriptionThe fronds of Laminaria and Saccharina species contain laminarin, a low molecular weight storage glucan. It is localized to the vacuoles. Laminarin structure contains β-(1,6)-intrachain linked (1,3)-β-d-glucan.
