Carboxylic acids were introduced by the reaction of the polysilane(II) with carboxylic acid anhydrides in the presence of an amine. Table 2 shows the results. In order to examine the effect of unsaturated bonds and halides in the side chain on photolysis, double bonds or chloride groups were introduced with the carboxylic acid. Polysilanes(III) were also soluble in polar solvents and basic aqueous solution. The solubility in tetramethyl ammonium hydroxide aqueous solution(TMAH) depended strongly... [Pg.145]

Flavanones elute before their corresponding flavones due to the effect of unsaturation between positions 2 and 3. [Pg.14]

Numerous additional tests to determine the effect of the carbon chain on the functional group were conducted using a homologous series. The effect of unsaturation is pronounced only in cases where the double bond is conjugated with the aldehydic functional group. For example, trans-2-hexenal ( ) had a AT value of 1.50 as compared to n-hexanal with a value of 0.93. The ease of electron delocalization in trans-2-hexenal, as shown below, increases the polarity of the molecule, hence its higher AT value. [Pg.516]

Various dynamic processes have been investigated using computer simulations of phospholipids. These include the dynamics of the alkyl chain movement of the phospholipid, the structure of water at the interface, diffusion of small molecules, interactions of phospholipids with water, dmgs, peptides, and proteins, and the effect of unsaturation or the presence of cholesterol on the phospholipid conformation. [Pg.305]

Note that there are other types of protons not listed here that can fall into the same chemical shift ranges listed above. The above categories are simply the most common ones. Also, through-space ( anisotropic ) effects of unsaturated groups (C=C, 0=0, and aromatic rings) can change chemical shifts from the above categories in ways that depend on conformation. [Pg.28]

In addition to structural characterization, quantitative analysis of the various species is important in many application areas. Due to the effect of unsaturation on the relative abundance of the [M+H]" and mass discrimination effects in favour of the DAG fragment ion in a quadrupole mass analyser, determination of response factors for the various species is required for an accurate quantitative analysis [24]. Therefore, limiting the number of standards that are required in the analysis of complex TAG mixtures is an important topic in quantitation. From a comparison of four different approaches, Byrdwell et al. [24] concluded that the most accurate method involved the calculation of response factors from contributions from individual fatty acids to the TAG response. This approach was apphed with good results by others as well [17]. [Pg.569]
