What is laminarin starch?
The molecule laminarin (also known as laminaran) is a storage glucan (a polysaccharide of glucose) found in brown algae. It is used as a carbohydrate food reserve in the same way that chrysolaminarin is used by phytoplankton, especially in diatoms. It is a linear polysaccharide, with a β(1→3):β(1→6) ratio of 3:1.
What is the meaning of laminarin?
Definition of laminarin : a polysaccharide that is found in various brown algae and yields only glucose on hydrolysis.
What are Fucosan vesicles?
Fucosan vesicles, found in brown algae, are small refractile vesicles that contain colourless acidic tannin- like phenolic chemical called fucosan. Fucosan protects the algae from epiphytic and endophytic growth.
How do you extract laminarin?
Laminarin can be extracted efficiently using high temperature conditions ranging from 50 to 90 °C with water as a solvent. Zha et al. (2012) studied the effect of the ratio of dried seaweed Laminaria japonica to water on the efficiency of laminarin extraction.
What is laminarin or mannitol?
Mannitol and laminarin are reserve foods of brown algae. Mannitol is a sugar alcohol form of mannose. Laminarin is a linear polysaccharide of mannitol containing β-1,3-linked glucose. Thus, this is the key difference between mannitol and laminarin.
What does mannitol mean?
Definition of mannitol : a slightly sweet crystalline alcohol C6H14O6 found in many plants and used especially as a diuretic and in testing kidney function.

What is Laminaria?
Laminaria is a type of seaweed that is native to Japan. Laminaria contains iodine, an element that the body needs to make thyroid hormones. It is also a rich source of iron and potassium.
What are the side effects of Laminaria?
In some people it can cause acne or worsen thyroid diseases. Laminaria is POSSIBLY UNSAFE when taken by mouth as a medicine. It contains iodine in amounts that are high enough to harm the thyroid, the gland that uses iodine to make hormones.
