 As Mars does not have a biosphere, there are probably no existing polymers on Mars.  All polymers will need to be imported and fabricated in the context of a martian settlement.

 In essence, a link is an alpha-link if the OH-group next to the oxygen in the ring (the one attached to the anomeric carbon) is on the opposite side of the ring's plane from the "tail" of the sugar, while it is a beta-link if on the same side<ref name="Wolfe">S.L. Wolfe - ''Molecular and cellular biology'' 1993. Wadsworth. ISBN 0-534-12408-9. p. 52.</ref>. The carbon atoms in a monosaccharide are numbered from 1 for the anomeric carbon and continuing along the chain, so cellulose can be denoted as a chain of glucose with <math>\beta ( 1 \rightarrow 4 )</math> links. All "glycosidic" links (the links that make up disaccharides and polysaccharides) connect an anomeric carbon of one monosaccharide to a different carbon of another or the same kind of monosaccharide<ref name="Smith" />.

 Saccharides can link together to form even longer molecules, such as [[cellulose]].  A common polymer in plants (often just called "fibre" by the food industry). Plants create cellulose by reacting glucose molecules with one another to link them into a long chain.  Chitin, shellac, lignin, silk and rubber are other examples of natural polymeric materials.
