.........................................................................................

  Cellulose IV₂

Linkage : beta 1-4     

Space Group : P1

Unit Cell Dimensions (a, b, c in Å and α, β, γ in °)

(No values are displayed if no information is available or the value is zero)

a (Å) = 8.10 - b (Å) = 8.10 - c (Å) = 10.34 - γ (°) = 90.00 - β (°) = 90.00 - α (°) = 90.00

Helix Type : anti-parallel two-fold helical, are marked by unequal rotational positions of the O(6) hydroxyl groups in adjacent residues, two chains

Method(s) Used For Structure Determination : X-ray diffraction and stereochemical model refinement
