One of the CBI Molecules being studied in the University of Massachusetts Amherst Chemistry-Biology Interface Program at UMass Amherst and on display at the Molecular Playground.
Alginate is a linear, organic polymer isolated from certain bacteria and algae. It has been shown to be biocompatible (non-toxic to human cells) and has found numerous applications as a biomaterial for cellular engineering.
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. The ratio of G/M in the alginate chain influences the strength of the gel and can be tuned by combining alginate obtained from different sources.

Owing to its unique physical properties, alginate hydrogels have been used for a number of biomaterial applications. Alginate has been used as a scaffold material for building artificial organs, as a dressing for ulcerous wounds and the targeted delivery of anti-cancer drugs.
The spinning molecule to the right is an example of a short chain of sodium alginate. Alginate can vary widely in length, monomeric sequence and G/M ratio depending on the source.
