Curdlan is a neutral ?-( 1, 3 )-glucan, perhaps with a few intra-or interchain 1, 6-linkages, produced as an exopolysaccharide by soil bacteria of the family Rhizobiaceae.

The more flexible and elastic keratins of hair have fewer interchain disulfide bridges than the keratins in mammalian fingernails, hooves and claws ( homologous structures ), which are harder and more like their analogs in other vertebrate classes.

One N-linked, glycosylation consensus sequence was identified in the protein coding region as well as an odd number of half cysteine residues, the latter of which would allow for interchain bonding or dimerisation of monomeric subunits.

While this type of stabilization is intuitive for intrachain interactions, rather than interchain interactions, scientists have proposed that perhaps the switch from intrachain salt bridges formed by acidic and basic residues to the interchain ionic associations contributes to the assembly of the filament.

Regarding the subunits, the ?-, ?-, and ?-chains were before found to have molecular weights ( MWs ) of ~ 95, 000, 78, 000, and 31, 000, respectively, all joined by interchain disulfide bridges.

Nylon 66 can have multiple parallel strands aligned with their neighboring peptide bonds at coordinated separations of exactly 6 and 4 carbons for considerable lengths, so the carbonyl oxygens and amide hydrogens can line up to form interchain hydrogen bonds repeatedly, without interruption ( see the figure opposite ).
