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 of BPA.
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.
