Edible seaweed Edible seaweed Edible seaweed, or sea vegetables, are algae that can be eaten and used in the preparation of food. They typically contain high amounts of fiber. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of polysaccharides such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. Most edible
Function field of an algebraic variety of a point over "K" is "K". The function field of the affine line over "K" is isomorphic to the field "K"("t") of rational functions in one variable. This is also the function field of the projective line. Consider the affine plane curve defined by the equation formula_10. Its function field is the field "K"("x","y"), generated by elements "x" and "y" that are transcendental over "K" and satisfy the algebraic relation formula_10. Function field of an algebraic variety In algebraic geometry, the function field of an algebraic variety "V" consists of objects which are interpreted as rational functions on "V".
