	Alginate is composed of a random sequence of mannuronic acid (M) and guluronic acid (G). Exposure to divalent cations (e.g. calcium, magnesium, etc.) chemically cross-links alginate solutions forming a gel. Alginate can vary widely in length, monomeric sequence and G/M ratio depending on the source. The ratio of G/M in the chain influences the strength of alginate hydrogels and can be tuned by combining alginate obtained from different organisms. The rotating molecule to the right is an example of a short chain of sodium alginate.		Alginate is composed of a random sequence of mannuronic acid (M) and guluronic acid (G).
