1 AMINO ACIDS Commonly, 21 L-Amino Acids Encoded by DNA Represent the Building Blocks of Animal, Plant, and Microbial Proteins
1 AMINO ACIDS Commonly, 21 L-amino acids encoded by DNA represent the building blocks of animal, plant, and microbial proteins. The basic amino acids encountered in proteins are called proteinogenic amino acids 1.1). Biosynthesis of some of these amino acids proceeds by ribosomal processes only in microorganisms and plants and the ability to synthesize them is lacking in animals, including human beings. These amino acids have to be obtained in the diet (or produced by hydrolysis of body proteins) since they are required for normal good health and are referred to as essential amino acids. The essential amino acids are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. The rest of encoded amino acids are referred to as non-essential amino acids (alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine). Arginine and histidine are classified as essential, sometimes as semi-essential amino acids, as their amount synthesized in the body is not sufficient for normal growth of children. Although it is itself non-essential, cysteine (classified as conditionally essential amino acid) can partly replace methionine, which is an essential amino acid. Similarly, tyrosine can partly replace phenylalanine. 1.1 The glutamic acid group 1.1.1 Glutamic acid and glutamine Free ammonium ions are toxic to living cells and are rapidly incorporated into organic compounds. One of such transformations is the reaction of ammonia with 2-oxoglutaric acid from the citric acid cycle to produce L-glutamic acid. This reaction is known as reductive amination. Glutamic acid is accordingly the amino acid generated first as both constituent of proteins and a biosynthetic precursor. -

DESIGN, SYNTHESIS AND STUDIES OF GUANIDINIUM-BASED INHIBITORS FOR ISOPRENOID BIOSYNTHETIC PATHWAY ENZYMES by Walid Abdelmagid MChem., The University of Liverpool, 2011 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF Doctor of Philosophy in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Chemistry) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) October 2019 © Walid Abdelmagid, 2019 i The following individuals certify that they have read, and recommend to the Faculty of Graduate and Postdoctoral Studies for acceptance, the dissertation entitled: DESIGN, SYNTHESIS AND STUDIES OF GUANIDINIUM-BASED INHIBITORS FOR ISOPRENOID BIOSYNTHETIC PATHWAY ENZYMES submitted by Walid Abdelmagid in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Chemistry Examining Committee: Martin Tanner Supervisor Stephen Withers Supervisory Committee Member Glenn Sammis Supervisory Committee Member Kathryn Ryan University Examiner David Chen University Examiner Additional Supervisory Committee Members: Supervisory Committee Member Supervisory Committee Member ii Abstract In this thesis an inhibition strategy was developed to target enzymes that utilize allylic diphosphates. Positively-charged inhibitors that mimic the transition states/intermediates formed with these enzymes were synthesized. In chapter two, inhibitor 2 containing a guanidinium moiety appended to a phosphonylphosphinate was designed to mimic the transition state for the dissociation of dimethylallyl diphosphate into an allylic carbocation-pyrophosphate ion-pair. To test for the effectiveness of incorporating a guanidinium functionality into inhibitors of human farnesyl diphosphate synthase, inhibitors 3 and 4 were also prepared. Inhibitor 3 has a positive charge localized onto one atom, and inhibitor 4 is isosteric to inhibitor 2, but lacks positive charge. The inhibitors displayed IC50 values that were significantly higher than the substrate Km value, indicating that the positive charge did not result in tight binding to the enzyme. -

Adverse Effects of Antioxidative Vitamins
REVIEW PAPERS International Journal of Occupational Medicine and Environmental Health 2012;25(2):105 – 121 DOI 10.2478/S13382-012-0022-x ADVERSE EFFECTS OF ANTIOXIDATIVE VITAMINS MACIEJ RUTKOWSKI1 and KRZYSZTOF GRZEGORCZYK2 1 Medical University of Łódź, Łódź, Poland Department of Clinical Chemistry and Biochemistry 2 Wł. Biegański Memorial Regional Specialistic Hospital, Łódź, Poland Department of Endoscopy and One Day Gastroenterology Abstract High doses of synthetic antioxidative vitamins: A, E, C and β-carotene are often used on long-term basis in numerous preventive and therapeutic medical applications. Instead of expected health effects, the use of those vitamins may however lead to cases of hypervitaminosis and even to intoxication. The article points out main principles of safety which are to be observed during supplementation with antioxidative vitamins. Toxic effects resulting from erroneous administration of high doses of those substances on organs and systems of the organism are also discussed. Attention is drawn to interactions of antioxidative vitamins with concomitantly used drugs, as well as intensification of adverse effects caused by various exo- genous chemical factors. Moreover, the article presents the evaluation of supplementation with these vitamins, which was performed in large studies. Key words: Vitamins A, E and C, β-carotene, Supplementation, Side actions, Toxic effects INTRODUCTION pharmaceutical drugs, and their preparations are gener- ally sold over the counter. However, it is commonly disre- Supplementation with synthetic antioxidative vitamins: garded that the excessive intake of antioxidative vitamins A, β-carotene (provitamin A), E and C, is widely propa- may be in fact harmful. Enthusiasts of at-home vitamin gated to-day, both as an adjunct to the applied pharma- supplementation, who blindly believe in newspaper rev- cotherapy and as one of factors to provide ”health and elations and advertisements, are therefore vulnerable to beauty”. -

H. Ekiert 2Chair of Inorganic and Analytical Chemistry, Faculty of Pharmacy, Jagiellonian University Medical College Head: dr hab. W. Opoka, prof. of Jagiellonian University Summary The use of herbs or their parts: leaves, roots, rhizomes, flowers, seeds, natural strains, as well as extracts or isolated metabolites is becoming more and more popular. Natural remedies not only act prophylactically, but also help to alleviate symptoms of many diseases and enhance the overall functioning of the internal organs. Many raw materials of natural origin plays a role in treatment of health problems, and also in case of serious diseases such as depression. Depres- sion (affective disorder) now affects about 10% of the population, but in next few years due to the development of civilization and increasing pace of life, the probable number of people suffering from this disease can grow rapidly. Natural raw materials such as Bacopa monnieri, Crocus sativus, Eleutherococcus senticosus, Griffonia simplicifolia, Hypericum perforatum, Sceletium tortuosum, Piper methysticum, Rhodiola rosea, Aspalathus linearis, Camellia sinensis, Ficus carica, Lycium chinense, Cuminum cyminum, Panax Ginseng can effectively assist the prevention and treatment of depression. Daily diet may also have positive effect in prevention of this disease. -

Opinion on Mixed Tocopherols, Tocotrienol Tocopherol And
The EFSA Journal (2008) 640, 1-34 Opinion on mixed tocopherols, tocotrienol tocopherol and tocotrienols as sources for vitamin E added as a nutritional substance in food supplements1 Scientific Opinion of the Panel on Scientific Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food (Question No EFSA Q-2005-146, Q-2005-172, Q-2006-265) Adopted on 22 February 2008 by written procedure PANEL MEMBERS Fernando Aguilar, Herman Autrup, Susan Barlow, Laurence Castle, Riccardo Crebelli, Wolfgang Dekant, Karl-Heinz Engel, Nathalie Gontard, David Gott, Sandro Grilli, Rainer Gürtler, John-Christian Larsen, Catherine Leclercq, Jean-Charles Leblanc, Xavier Malcata, Wim Mennes, Maria-Rosaria Milana, Iona Pratt, Ivonne Rietjens, Paul Tobback, Fidel Toldrá. SUMMARY Following a request from the Commission, the Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food (AFC) has been asked to evaluate the safety and bioavailability of mixed tocopherols, tocotrienol tocopherol and tocotrienols as a source for vitamin E when added for nutritional purposes in food supplements. The present opinion deals only with the safety and bioavailability of three particular sources of vitamin E, intended for the general population, to be added in food supplements. The safety of vitamin E itself, in terms of amounts that may be consumed, is outside the remit of this Panel. Vitamin E has been evaluated by the Scientific Committee on Food (SCF) who set a tolerable upper intake level (UL) of vitamin E (as d-alpha-tocopherol) for adults of 300 mg alpha- tocopherol equivalents /day. JECFA has defined an Acceptable Daily Intake (ADI) of 0.15-2 mg/kg bw/day calculated as alpha-tocopherol. -
