Oct 14, 2018· Cell Wall Definition. A cell wall can be defined as a rigid layer that encircles the contents of the cell. This is a semi-permeable layer that acts as a protective layer in certain types of cells. As such, the cell wall will be seen outside of the cell membrane in the cells of the following organisms: Plant cells; Fungi; Bacteria; Algae; Some archaea
Sodium Alginate (alginate, algin) | Molecular Recipes
Sodium Alginate Function Sodium alginate is used to gel in presence of calcium, as shear-thinning thickener in absence of calcium, to stabilize emulsions or foams and to form films. In modernist cuisine, sodium alginate is mostly used with calcium salts to produce small caviar-like and large spheres with liquid inside that burst in the mouth.
