Is Tegaderm alginate the same as calcium alginate?

Sodium alginate, produced as described above, is the main form of alginate in use. Smaller quantities of alginic acid and the calcium, ammonium and potassium salts, and an ester, propylene glycol alginate, are also produced.

What are the two types of alginate?

Alginates are made up of two uronic acids: d-mannuronic acid (M) and l-guluronic acid (G) extracted from brown seaweeds Phaeophyceae and kelp [68,69]. The alginic acid form of alginate is extracted from the seaweed in alkaline conditions, then precipitated and ion exchanged (e.g., with potassium).
