    So an alginate molecule can be regarded as a block copolymer containing M, G, and MG blocks, the proportion of these blocks varying with the seaweed source. However Larsen (1981) warns that this is an idealized structure which is at best an approximation of the actual situation.

    Introduction to Alginate - Structure | CyberColloids

    Structure of Alginate. Alginate was originally thought to consist of a uniform polymer of mannuronic acid as shown in figure 1. However later studies showed the presence of guluronic acid residues and it is now understood that alginate is a linear co-polymer of β-D-Mannuronic acid and α±-L-Guluronic acid.
