Objective: The goal of this project is to develop an automated synthesis of the Streptococcus pneumoniae 7F capsular polysaccharide repeating unit
, which is of high interest for synthetic vaccines against this pathogen.
The main repeating unit
in each oligomer group was identified as those composed of catechin (IV and VI).
5), where the repeating unit
contains two carbon atoms and four hydrogen atoms, the molecular weight is 28n, where n represents the number of repeating segments.
Figure 1 shows the chemistry for the repeating unit
of what is generically referred to as a silicone polymer.
The mass increment of the repeating unit
is 74 Da, and corresponds to a fragment of glycerine.
Thus, from a conceptual point of a view, it appears as if it is much more important to identify the repeating unit
than it is to be able to create complex repeating patterns.
I've combined these texts according to this repeating unit
Using the repeating unit
geometry of each stent design, solid models were generated [Fig 1,2,3,4].
Each repeating unit
contains all three genes in the order of 18S-5.
In developing the 2D model the following procedure was used: Consider the stent structure as having a radius r, the repeating unit
subtends an angle[phi], equal to 360/nrep, where nrep represents the number of the repeating units
in the circumferential direction.
The repeating unit
of this type of fibre is the amide link (Fig 5), where R is a side chain of one of the twenty different naturally-occurring amino acids that proteins are derived from.
For example, [DELTA] O is a repeating unit
or element of a pattern containing [DELTA] O [DELTA] O [DELTA] O.
