The complex linkage and the mean degree of polymerization (mDP) of procyanidins may affect their absorption, bioavailability and metabolism [ 29].
The mean degree of polymerization of 'LAN3017' PAs was also higher than those from 'Courier' and 'Solido'.
Additionally, the mean degree of polymerization of 'LAN3017' PAs are 2 3 fold higher than 'Courier' or 'Solido PAsSolido PAs
PA free monomers, polymer subunit compositions, and mean degree of polymerization (mDP) did not differ significantly between nearly-isogenic black (iRT) and brown (irT) seed coats.
Flavan- 3-ol PA extension units form phloroglucinol adducts at their C4 position while terminal flavan- 3-ol units are released as flavan- 3-ol monomers, the ratio of which allows determination of the mean degree of polymerization (mDP).> -wrap-foot> aMolar % ± SE (n = 2); bnd, not detected; cYield of PA extract calculated.
To examine this hypothesis, control experiments were performed using a methylated PETTC RAFT agent (Me-PETTC) to prepare a PGMA macro-CTA with a mean degree of polymerization (DP) of 59, which was subsequently chain-extended with HPMA to produce an analogous near-monodisperse H3COOC PGMA59 PHPMA160 diblock copolymer (see Figure S2 in the Supporting Information).
Interestingly, 4 PAs were found to be exclusive to the black (iRT) seed coat (Table 2) however the total subunit compositions, the mean degree of polymerization (mDP), and the total amounts of soluble and solvent-insoluble PAs were not different compared to the brown (irT) seed coat (Additional file 2: Figure S1).
Number and weight average degrees of polymerization were computed by means of generating functions.
Observations around the gel point, for low polymerization voltages, show that the gel fraction exponent β and the weight average degree of polymerization exponent γ agree with the mean-field results for low acrylamide concentrations.
A series of brush-like macromolecules with the same number average degree of polymerization of a poly 2-hydroxyethyl methacrylate) backbone, Nn = 2,150 ± 100, and different degrees of poly 2-hydroxyethyloly(n-butyl acrylate) (pBA) side chains ranging fromethacrylate to n = 140 ± 12 were synthesized backbonetraNnfer radical polymerization (see 'Polymer Characterization' in the Methods)18.
