Sea-algae derived alginate is an example of a:

Sea-algae derived alginate is classified as a polymer due to its structural composition and properties. Alginate is a naturally occurring polysaccharide made up of monomeric units of guluronic acid and mannuronic acid, which are linked together to form long chains. This characteristic of being composed of repeating units is a defining feature of polymers, which are large molecules made up of smaller subunits.

In the context of tissue engineering, alginate is particularly valued for its biocompatibility, biodegradability, and ability to form hydrogels, which can support cell growth and tissue formation. Its utility in creating scaffolds for tissue regeneration makes it a highly relevant material in this field.
