VITAMIN B6 Vitamin B6 isolated in 1930.The term B6 refer to six common forms, namely Piridoxal, Pyridoxine, Piridoxamine, and their Phospharylated forms. The phosphate ester derivate piridoxal-5-phosphate (PLP)is the bioactive coenzyme form involved in over 4% of all enzymatic reactions, must be obtained from the diet because humans cannot synthesize it, it ´s a water soluble vitamin B group, and it serves as a coenzyme in many enzyme reaction in amino acid , glucose and lipid metabolism.
Microbial production of vitamins- To fulfill the increasing worldwide demand and to reduce the cost of vitamins different group of researchers are using different microorganisms for the production of vitamins like vitamin B12, vitamin C, vitamin B2 and vitamin D. Here in this review I have mentioned some of them which are producing good yield of vitamins. Vitamin B12- Vitamin B12 (Cobalamin) is having great worldwide demand due to its important role in growth and metabolism of the living cell. J
1.0 INTRODUCTION Fungi have been significant in both past and modern biotechnological processes (Bennett, 1998). After World War I, a traditional fungal biotechnology has begun and developed into yielding of enzymes, antibiotics, hormones, citric acids, vitamins, and fungicides (Demain, 2000). This list will continue expanding as we moved in this modern century. Fungi definitely bring lots of benefits in pharmaceutical and economic industries. For instance, pharmaceuticals and personal care products
Introduction Enzymes are proteins that increase the speed of reactions in cells. They are catalysts in these reactions which means that they increase the speed of the reaction without being consumed or changed during the reactions. Cofactors are required by some enzymes to be able to carry out their reactions by obtaining the correct shape to bind to the other molecules of the reaction. Chelating agents are compounds that can disrupt enzyme reactions by binding to metallic ions and change the shape
Introduction: So what is an enzyme? An enzyme is “any protein that acts as a catalyst, increasing the rate at which a chemical reaction occurs. The human body probably contains about 10,000 different enzymes.”(Farlex) The active site or sites of every enzyme are composed of a particular array of amino acids. The active site exhibits specificity for the substrate of the enzyme. The enzyme should bind and catalyze the reaction for its specific substrates better than with any other substrates. Therefore
Introduction: Enzymatic reactions have played arguably one of the most important roles in the evolution of complex cellular life. By using proximity interactions to achieve thermodynamic favorability, enzymes are able to catalyze reactions that would have never occurred on a reasonable human time scale. This paper will highlight the importance of an enzyme aptly named “dihydrofolate reductase”, which has an integral role in an essential metabolic pathway. Spanning across thousands of organisms,
The purpose of this assessment was to research, design and conduct an experimental investigation on the effect of substrate concentration (manipulated by increasing concentration of pH buffer) of catalysed reactions by measuring the volume of oxygen produced as the reaction proceeded. Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being altered itself. Enzymes are also proteins that fold into complex shapes that allow smaller molecules
Gene expression is the ability of a gene to produce a biologically active protein. This process is regulated by the cells of an organism, it is very important to the survival of organisms at all levels. This is much more complex in eukaryotes than in prokaryotes. A major difference is the presence in eukaryotes of a nuclear membrane, which prevents the simultaneous transcription and translation that occurs in prokaryotes. Initiation of protein transcription is started by RNA polymerase. The activity
structural component of various proteins[9]. Furthermore, It works as an antioxidant, anti-inflammatory agent and signaling mediator contributing to its vital roles in immunity, wound healing, and tissue repair.[10, 11] 2.1. Zinc in proteins: Zinc is a cofactor in over 300 metalloproteins including RNA and DNA polymerase, thus indispensable part for protein synthesis, DNA synthesis, and cell growth. Zinc proteins are estimated to be around about 10% of the human proteome.[12] The essentiality of zinc in
Once the vascular component has been assessed, we get a clear idea of the main limiting organic factor in wound healing. We can then build on this information by assessing the patient 's cofactors in healing. This step is essential in order to maximize the vascular network the patient possesses. Those cofactors are: 1. Systemic diseases (Diabetes, immunosuppression, skin disease) 2. Nutrition/Diet (Low protein diet, vitamin deficiencies) 3. Medication (Corticosteroids, immunosuppressive drugs and
Cellular respiration is an important function for the body to obtain energy (Citovsky, Lecture 18). There are two types of cellular respiration; aerobic conditions and anaerobic conditions. Aerobic conditions are the cellular respiration occurred with oxygen while anaerobic conditions are cellular respiration occurred without oxygen. The most common cellular respiration is aerobic conditions where oxygen were supplied for phosphorylation (Campbell et al., pg 177). In human body, anaerobic conditions
an essential water soluble vitamin that must be carefully regulated to prevent deficiency related complications in the nervous, gastrointestinal, and cardiovascular systems (e). This review begins with a discussion of B12 absorption and role as a cofactor for L-methylmalonyl-CoA mutase and methionine synthase (e). Laboratory findings are interpreted along with associated disease conditions. Finally, assay methods are discussed including blood smear and complete blood count, B12 competitive-binding
1. INTRODUCTION OF THE MATRIX INVERSION METHODS 1.1 MATRIX :- • A matrix is defined as an ordered rectangular array of numbers. • A matrix is a system in which m.n elements are arranged in a rectangular formation of m rows and n columns bounded by brackets []. • This formation is sometimes more explicitly known as m by n matrix, and written as m*n matrix. • Each of the numbers of this formation is called an element of the matrix. • A matrix represented by a capital letter such as A, B, etc.
The Rate of Hydrolysis of Sucrose Hypothesis - The digestion of sucrose into glucose and fructose is carried out by the presence of the enzyme Sucrase. The activity of the enzyme will be greatest at its optimum temperature since at this temperature the enzyme's tertiary structure will be correct to allow the formation of the substrate-enzyme complex quickly and efficiently. This should be at 37°C (body temperature), which is the temperature of the ileum where Sucrase is secreted and naturally
ADMA in OSA It is now well established that OSA is a cardiovascular risk factor, and that ADMA has the potential to exacerbate cardiovascular disease. But does OSA influence ADMA levels? Many studies show increases in ADMA levels in OSA patients; Barcelo et al measured plasma ADMA in 23 OSA patients and found it significantly higher (1.17 μmol/L) compared to control (0.87 μmol/L, P<0.01) (55). Ozkan et al also found that ADMA levels were higher in OSA patients but levels did not reach statistical
Methylenetetrahydrofolate Reductase (MTHFR) Methylenetetrahydrofolate reductase also known as MTHFR is a gene that is essential for healthy development. This gene produces an enzyme that aids in the absorption of folate, as well as other vitamins and minerals. An MTHFR gene mutation however can cause serious issues. This mutation will prevent one from obtaining the nutrients they need from the foods they eat. The effects of MTHFR mutation, such as living with severe inflammation, irritable bowel
vitamin is water-soluble (Bemeur & Butterworth 2014). Therefore, this fortification increases the intake of thiamine by consumers, hence reducing the occurrence of a deficiency such as beri beri (Bettendorff 2012). Riboflavin (vitamin B2) is a cofactor in carbohydrate and fat metabolism (Branen et al. 2005). The addition of riboflavin in the cereal lowers risk of deficiency of the vitamin which may lead to stomatitis, cheilosis, rashes as well as anaemia (Ball 2005). Niacin (vitamin B3) is important

Collagen assists in the formation of bones and teeth, and helps to heal separated tissues and form scars. Side effects of vitamin C deficiency
Hemophilia is an inherited disease which slows the blood clotting process due to missing or reduced clotting factor proteins. Although uncommon, it is possible for Hemophilia to be acquired if the body produces antibodies that attack clotting factors. Only 30% of Hemophilia cases are due to spontaneous mutations. Hemophilia is a rare disorder. Approximately 1 in 5000 males has Hemophilia. The disorder is much more common in males than females. It is estimated that over 400000 individuals worldwide
