Structural Characterization Of Fucoidan And Its Role In The Hemizona Assay, Manish S. Patankar
Structural Characterization Of Fucoidan And Its Role In The Hemizona Assay, Manish S. Patankar
Chemistry & Biochemistry Theses & Dissertations
Fucoidan is a polysaccharide commonly found in brown algae. It is a sulfated polymer of the monosaccharide L-fucose. Fucoidan is thought to function in water retention by algae. Commercially available fucoidan is extracted from a brown algae called Eurus vesiculosus.
This polysaccharide has immense potential as a biologically active agent: (i) it exhibits anticoagulant action, (ii) it has also been reported to block retroviral replication and (iii) it is capable of blocking sperm-egg binding in sea urchin, mouse and rabbit. Recently, fucoidan has also been shown to block the interaction of human sperm and egg in the hemizona assay …
Isolation And Characterization Of The Triiodothyronine Regulatory Region Of The Fatty Acid Synthase Gene In Avian Species, Delfina Rivera Valencia
Isolation And Characterization Of The Triiodothyronine Regulatory Region Of The Fatty Acid Synthase Gene In Avian Species, Delfina Rivera Valencia
Masters Theses
Fatty acids are utilized for energy storage in the form of triglycerides or neutral fats. One way to regulate fatty acid biosynthesis is to regulate the activity of fatty acid synthase (FAS), the enzyme that catalyzes the reaction. Previous studies have shown that regulation of FAS activity and synthesis is regulated by the hormone triiodothyronine, T3, at the level of transcription. Thus, isolation and characterization of the promoter region o f the FAS gene will enable the identification of the thyroid hormone response elements (TREs). This study could shed light on the mechanisms on how this gene can …
Biochemical Investigation Of Gout And Its Familial Incidences, Chin-Ling Hsu
Biochemical Investigation Of Gout And Its Familial Incidences, Chin-Ling Hsu
Chemistry & Biochemistry Theses & Dissertations
Gout is a chronic metabolic disorder caused by deposition of uric acid on the joint. It is categorized into two types: primary and secondary. Primary gout is uric acid overproduction, caused by excessive synthesis of the purine precursors. Secondary gout occurs also as the result of overproduction or decreased renal excretion of uric acid resulting from other disease processes or medication.
The two purine bases, hypoxanthine and xanthine, liberated from ribosides by the action of nucleoside phosphorylase, are degraded to uric acid as the final excretory product in the purine degradation pathway. Hypoxanthine and xanthine are the physiological substrates of …
Kinetic Characterization Of A Recombinant C-Terminal Mutant Of Reverse Transcriptase From The Human Immunodeficiency Virus, Thomas S. Heard
Kinetic Characterization Of A Recombinant C-Terminal Mutant Of Reverse Transcriptase From The Human Immunodeficiency Virus, Thomas S. Heard
Chemistry & Biochemistry Theses & Dissertations
The human immunodeficiency virus (HIV) reverse transcriptase (RT) (EC 2.7.7.49) is the central replication enzyme for HIV. In general, the kinetic mechanism for this and all other polymerases involves the ordered binding of two substrates: a primer-template (PT) followed by a deoxyribonucleoside triphosphate (dNTP). Previous investigations prompted this research when it was discovered that the substrate dNTP, in absence of PT, could protect a recombinant c-terminal mutant HIV-1 RT from inhibition by pyridoxal-5'-monophosphate (PLP), an active-site dNTP inhibitor. In contrast, the non-mutant recombinant HIV-1 RT required both substrates for protection from PLP inhibition. This investigation sought to determine if this …
Biochemical Analysis Of Human Seminal Plasma, Jamshed Ayub
Biochemical Analysis Of Human Seminal Plasma, Jamshed Ayub
Chemistry & Biochemistry Theses & Dissertations
Presently there is no single biochemical criterion for differentiating between a potentially fertile male and an infertile male. However, for evaluating male fertility the biochemical analysis of seminal plasma is a very convenient and quantitative technique if it is combined with careful clinical examination.
In seminal plasma analysis, fructose and proteins are chemical indicators of seminal vesicle activity, citric acid and acid phosphatase indicate prostate function while glycerolphosphorylcholine indicates epididymis activity. In this research these five indicators are studied and an attempt is made to establish their normal ranges.
This study shows that the data obtained from the seminal plasma …
