Research lists as fucoidan sources a number of common marine algae familiar to the Japanese diet, including kombu, wakame, hijiki, mozuku, [2] and gagome (Kjellmaniella), [23] [24] and other algae such as wracks (Fucus distichus ssp. evanescens) [24] and marine animals, including abalone, scallops, sea urchin, and sea cucumber.

A group of researchers from Okinawa Institute of Science and Technology Graduate University conducting DNA research decoded S-strain genome for Cladosiphon okamuranus and found that its size was roughly 140 Mbp and smaller relative to other brown alga.
In a small human clinical trial to evaluate the safety and efficacy of fucoidan ingestion (brown seaweed extract), 3g daily of 75% w/w oral fucoidan for 12 days increased the proportion of CD34+CXCR4+ from 45 to 90% and the serum SDF-1 levels, which could be useful in CD34+ cells homing/mobilization via SDF-1/CXCR4 axis.

Kjellmaniella is a monotypic genus of kelp (large brown algae) comprising the species Kjellmaniella crassifolia, known as kagome (カゴメ/籠目) in Japanese. [5] [6] The species has received attention in recent years for fucoidan content [7] and its multilateral profile of fucoidan chemicals compared to other seaweeds.
They have cellulose walls with alginic acid and also contain the polysaccharide fucoidan in the amorphous sections of their cell walls. A few species (of Padina) calcify with aragonite needles. [26] In addition to alginates, fucoidan and cellulose, the carbohydrate composition of brown algae consists of mannitol, laminarin and glucan. [52]
Fucose is a hexose deoxy sugar with the chemical formula C 6 H 12 O 5.It is found on N-linked glycans on the mammalian, insect and plant cell surface. Fucose is the fundamental sub-unit of the seaweed polysaccharide fucoidan. [1]
Research published in 2014 by Long Yu et al. examined the chemical properties of this organism that makes it such a delicacy. They found that they contained a polysaccharide that is present in brown algae and sea cucumbers called Fucoidan, that contains L-fucose and sulphate groups, which is a primary component aiding their popularity.
