The file Glycogen.pdf shows which of the D-glucose candidates can make
the 1,4- and 1,6-linkages that are characteristic of glycogen. Each of
the D-glucose di-L-triplets was tested to see if it can join with an
identical di-triplet in the same orientation to make the 1,4- and

 Because the structural joining of the triplets and di-triplets is
C-atom to C-atom, each of the candidates was tested to see if it could
make the 1,4- and 1,6-linkages C-atom to C-atom. Each was then tested
to see if it could make the same linkages C-atom to O-atom to C-atom.

Three di-triplets could make only C-C glycogen links; four could make
only C-O-C links; and four could not make both links either C-C or

The linkages between the di-triplets is shown in the figures. Both
1,4-strands and 1,6-strands are shown for several di-triplets. In some
cases, the linking of 1,4-strands by 1,6-strands is shown. The
geometry of the glycogen joins is shown in vector diagrams for each
di-triplet which can make the linkages. A table shows the angle
between the strands for each of these di-triplets.

The file is 34 pages long and has 32 figures and 1 table. It can be
downloaded from the "Files for sharing" page of the website
