Prolonging Healthy Aging: Longevity Vitamins and Proteins PERSPECTIVE Bruce N
PERSPECTIVE Prolonging healthy aging: Longevity vitamins and proteins PERSPECTIVE Bruce N. Amesa,1 Edited by Cynthia Kenyon, Calico Labs, San Francisco, CA, and approved September 13, 2018 (received for review May 30, 2018) It is proposed that proteins/enzymes be classified into two classes according to their essentiality for immediate survival/reproduction and their function in long-term health: that is, survival proteins versus longevity proteins. As proposed by the triage theory, a modest deficiency of one of the nutrients/cofactors triggers a built-in rationing mechanism that favors the proteins needed for immediate survival and reproduction (survival proteins) while sacrificing those needed to protect against future damage (longevity proteins). Impairment of the function of longevity proteins results in an insidious acceleration of the risk of diseases associated with aging. I also propose that nutrients required for the function of longevity proteins constitute a class of vitamins that are here named “longevity vitamins.” I suggest that many such nutrients play a dual role for both survival and longevity. The evidence for classifying taurine as a conditional vitamin, and the following 10 compounds as putative longevity vitamins, is reviewed: the fungal antioxidant ergo- thioneine; the bacterial metabolites pyrroloquinoline quinone (PQQ) and queuine; and the plant antioxidant carotenoids lutein, zeaxanthin, lycopene, α-andβ-carotene, β-cryptoxanthin, and the marine carotenoid astaxanthin. Because nutrient deficiencies are highly prevalent in the United States (and elsewhere), appro- priate supplementation and/or an improved diet could reduce much of the consequent risk of chronic disease and premature aging. vitamins | essential minerals | aging | nutrition I propose that an optimal level of many of the known adverse health effects. -
Nucleotide Metabolism 22
Nucleotide Metabolism 22 For additional ancillary materials related to this chapter, please visit thePoint. I. OVERVIEW Ribonucleoside and deoxyribonucleoside phosphates (nucleotides) are essential for all cells. Without them, neither ribonucleic acid (RNA) nor deoxyribonucleic acid (DNA) can be produced, and, therefore, proteins cannot be synthesized or cells proliferate. Nucleotides also serve as carriers of activated intermediates in the synthesis of some carbohydrates, lipids, and conjugated proteins (for example, uridine diphosphate [UDP]-glucose and cytidine diphosphate [CDP]- choline) and are structural components of several essential coenzymes, such as coenzyme A, flavin adenine dinucleotide (FAD[H2]), nicotinamide adenine dinucleotide (NAD[H]), and nicotinamide adenine dinucleotide phosphate (NADP[H]). Nucleotides, such as cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), serve as second messengers in signal transduction pathways. In addition, nucleotides play an important role as energy sources in the cell. Finally, nucleotides are important regulatory compounds for many of the pathways of intermediary metabolism, inhibiting or activating key enzymes. The purine and pyrimidine bases found in nucleotides can be synthesized de novo or can be obtained through salvage pathways that allow the reuse of the preformed bases resulting from normal cell turnover. [Note: Little of the purines and pyrimidines supplied by diet is utilized and is degraded instead.] II. STRUCTURE Nucleotides are composed of a nitrogenous base; a pentose monosaccharide; and one, two, or three phosphate groups. The nitrogen-containing bases belong to two families of compounds: the purines and the pyrimidines. A. Purine and pyrimidine bases Both DNA and RNA contain the same purine bases: adenine (A) and guanine (G). -

The synthesis of uridine diphosphate glucose (UDPG), cytidine diphosphate choline (CDP- choline), glucose-l-phosphate (G1P) and glucose-6-phosphate (G6P) has been accomplished under simulated prebiotic conditions using urea and cyanamide, two condensing agents considered to have been present on the primitive Earth. The synthesis of UDPG was carried out by reacting G1P and UTP at 70 °C for 24 hours in the presence of the condensing agents in an aqueous medium. CDP-choline was obtained under the same conditions by reacting choline phosphate and CTP. G1P and G6P were synthesized from glucose and inorganic phosphate at 70°C for 16 hours. -

Showalter, Co-Chair Associate Professor George A. Garcia, Co-Chair Professor Hashim M. Al-Hashimi Assistant Professor Garry D. Dotson Assistant Professor Matthew B. Soellner © Allen F. Brooks 2012 In memory of Edward and Lillian Pederson ii Acknowledgements With my remaining time short, it is appropriate to look back and thank those that supported me in my dissertation work either professionally or as a friend. First and foremost, I have to acknowledge my best friend from the program, Adam Lee. If it was not for the trip to the ACS meeting in Chicago, Adam and I likely would have never got to know each other. Luckily, fate arranged such an occurrence. If not for Adam’s friendship and the support of some others, I likely would have left the program in my second year. I also have to thank Jason Witek, an undergraduate who worked in the Showalter lab. We actually met during the Organic Mechanisms course, as he was in an academic program of his own design. The time we worked together in the lab was a productive one, and interestingly an amusing time as well. I also have to thank several other associates for their help in progressing my research as well as making time here more pleasant, those individuals being: Dr.
