  Glucomannan

Linkage : beta 1-4     

Space Group : orthorhombic I222

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) = 9.01 - b (Å) = 16.73 - c (Å) = 10.40 - γ (°) = 90.00 - β (°) = 90.00 - α (°) = 90.00

Helix Type : 2-fold helix. The unit cell contains 4 chains with anti-parallel packing polarity and eight water molecules

Method(s) Used For Structure Determination : X-ray data and constrained linked-atom least-squares model refinement
