Equation (3) uses the molar masses of carboxyl
ends, amine ends, water, and amide links (which are 115.15, 58.10, 18.02 and 155.23 g mol-1, respectively) to compute [L], which is the number of moles of amide links in 106 g of polymer.
Secondary structure occurs when, let's say, Mary's carboxyl
group H-bonds to Joe's amino group.
indices of PLA and PLA/CNC composite films are illustrated in Fig.
In the spectrum of Schiff base L-3, the asymmetric carboxyl
stretching (COO-) was observed at 1640 cm-1 which shifted on complexation at with Cu(II), Pd(II) and Pt(II ) ions at 1643, 1630 and 1636 cm-1, respectively.
The nucleation of the apatite layer is initialed by specific functional groups such as Si-OH , Ti-OH , carboxyl
group (-COOH), and phosphate group [29, 30] derived from the surface of the materials.
By changing the nature of the carboxyl
groups at the molecule's tips and by altering the spacing between the groups, Rebek can tailor his compounds to recognize a wide variety of specific substrates, including acids, metal ions and certain neutral compounds.
The imidazole and carboxyl
groups in IA were intended to improve the antifungal activity and water compatibility of PU, respectively.
The liquid-phase polymerization is commonly used in the final stage of polymerization from low molecular weight prepolymer (e.g., degree of polymerization (D[P.sub.n]) = 20-30, carboxyl
end group concentration ([COOH]) = 60-80 mmol/kg) to produce conventional PET (e.g., D[P.sub.n] = 100, carboxyl
end group concentration ([COOH]) = 20-35 mmol/kg).
the adhesive composition should be made on the basis of high-pressure polyethylene with grafted functional anhydride and carboxyl
groups, and provide quality indicators of the protective coating in accordance with gost 9
Feed amino acids refer to the family of organic compounds which consists of carboxyl
and amino groups.
Summary: Feed amino acids refer to the family of organic compounds which consists of carboxyl
and amino groups.
In this way, it can adjust the distance between the aromatic ring and carboxyl
