synthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولNeonatal umbilical cord blood lipoproteins. Isolation and characterization of intermediate density and low density lipoproteins.
Intermediate density lipoproteins (IDL) (d = 1.006 to 1.019 g/ml) and low density lipoproteins (LDL) (d = 1.019 to 1.063 g/ml) were isolated from human umbilical cord blood plasma by sequential ultracentrifugation. The concentration, chemical and apolipoprotein composition, size and size distribution of the neonatal IDL and LDL for both sexes were determined. The IDL and LDL from the neonates s...
متن کاملSeparation and Characterization of Human Serum
During the early phase of transport of exogenous fats, lymph and blood assume a milky appearance due to an increase of large fat particles, known as chylomicrons. Separation can be achieved by chemical means; protamine sulfate (1), toluidine blue (2), heparin and calcium chloride (3, 5), polyvinylpyrrolidone (4); however, ultracentrifugation (6) is the method commonly used. Chemical characteriz...
متن کاملSeparation and Characterization of Human Serum Chylomicrons
Chylomicrons were separated by low and high speed ultracentrifugation from lipemic sera of human subjects in the absorptive phase. The final chylomicron preparation was free from other serum components and contained a small constant amount of protein, approximately 2 per cent of the chylomicron fraction. Electrophoresis, immunochemical analysis, and absorption experiments identified the protein...
متن کاملUmbilical cord blood lipoproteins. Isolation and characterization of high density lipoproteins.
High density lipoproteins (d = 1.063 to 1.21 g/ml) were isolated from both individual and pooled umbilical cord blood plasma by sequential preparative ultracentrifugation. Mean total HDL concentration was 139 ± 9.1 mg/dl, with mean values for cholesterol and triglyceride of 24.9 mg/dl and 5.0 mg/dl, respectively. The particle size distribution of HDL particles was examined by gradient gel elect...
