“…It is required for carnitine biosynthesis and the synthesis of neurotransmitters. In the central nervous system, intracellular ascorbate acts as an antioxidant, and it is necessary for peptide amidation, myelin formation, and in protecting against glutamate toxicity [308]. More amyloid-β plaque deposits have been observed in mice with moderate intracellular vitamin C deficiency [309].…”

Happily (n)ever after: Aging in the context of oxidative stress, proteostasis loss and cellular senescence

Aging is a complex phenomenon and its impact is becoming more relevant due to the rising life expectancy and because aging itself is the basis for the development of age-related diseases such as cancer, neurodegenerative diseases and type 2 diabetes. Recent years of scientific research have brought up different theories that attempt to explain the aging process. So far, there is no single theory that fully explains all facets of aging. The damage accumulation theory is one of the most accepted theories due to the large body of evidence found over the years. Damage accumulation is thought to be driven, among others, by oxidative stress. This condition results in an excess attack of oxidants on biomolecules, which lead to damage accumulation over time and contribute to the functional involution of cells, tissues and organisms. If oxidative stress persists, cellular senescence is a likely outcome and an important hallmark of aging. Therefore, it becomes crucial to understand how senescent cells function and how they contribute to the aging process. This review will cover cellular senescence features related to the protein pool such as morphological and molecular hallmarks, how oxidative stress promotes protein modifications, how senescent cells cope with them by proteostasis mechanisms, including antioxidant enzymes and proteolytic systems. We will also highlight the nutritional status of senescent cells and aged organisms (including human clinical studies) by exploring trace elements and micronutrients and on their importance to develop strategies that might increase both, life and health span and postpone aging onset.

“…However, synthetic vitamins have an overall lower bioactivity and availability, and they can certainly not fully replace naturally healthy plant-derived food. Furthermore, several clinical symptoms have been associated with overdose of particular vitamins (Chawla and Kvarnberg 2014). In plants, the individual vitamins hardly occur in a single, pure form, but chemically modified or as part of various organic complexes.…”

“…Supplements containing all eight are referred to as vitamin B complex. Overdose of individual members of the B vitamin group, particularly vitamin B6 can have adverse effects (Lheureux et al 2005;Chawla and Kvarnberg 2014). It is reasonable to assume that B vitamins are of optimal value for human nutrition if they do not exceed a certain threshold, and if a balanced ratio exists between the individual members.…”

Synthetic vitamin preparations have grown in popularity to combat health risks associated with an imbalanced diet, poor exercise and stress. In terms of bioavailability and diversity, they lack behind vitamins naturally occurring in plants. Solutions to obtain plant-derived vitamins at a larger scale are highly desirable. B vitamins act as precursors of enzymatic cofactors, thereby regulating important metabolic processes both in animals and plants. Because during plant germination, the vitamin content and micronutrient availability increase, sprouts are generally considered a healthier food as compared to dry grains. Germination only occurs if a plant′s antioxidant machinery is sufficiently activated to cope with oxidative stress. Seeds of quinoa, an edible gluten-free plant naturally rich in minerals, germinate readily in a solution containing the eight B vitamins. We studied biochemical changes during quinoa germination, with a focus on nutritionally relevant characteristics. The results are considered from a nutritional and plant physiological perspective. Germination of quinoa in vitamin-rich medium is a promising strategy to enhance the nutritional value of this matrix. Additional health-beneficial effects indirectly resulting from the vitamin treatment include elevated levels of the multi-functional amino acid proline and a higher antioxidant capacity. Plant biomolecules can be better protected from oxidative damage in vivo.

“…Although the original substance termed vitamin B3 was shown to be pantothenic acid, that alphabetical name is often but erroneously used for niacin . The term is still commonly found in current scientific literature and popular sources such as Wikipedia . The reasons for this are not clear, but it has been suggested that the name was brought back into use in a book called the Vitamin B‐3 Therapy by a co‐founder of Alcoholics Anonymous, who wanted a more acceptable name for niacin, which was being used to treat alcoholism…”

Aim The aims of this paper were to catalogue a complete list of all the alphabetical names for vitamins that have appeared in the scientific literature, provide the citations of their first use and seek explanations for any apparent gaps in the naming system. Methods The names of known vitamins and pseudo-vitamins were identified from standard nutrition textbooks, historical monographs and several review articles. If the first citation for the alphabetical vitamin name was not found in these sources, additional searches were conducted in the Scopus and Medline databases, in Google and Google Scholar, using the names of vitamins as search terms. Results Sixty-seven different alphabet-based vitamin names were tabulated, including where possible the scientific and alternative names, a description of the source substance, physiological roles and the first citation of the alphabetical name. The results show that all the letters of the alphabet have been used to describe putative vitamin compounds. The simple alphabetical naming system proposed by Drummond in 1920 lasted for less than a decade. A number of other systems have been used based on the name of the discoverer, the source of the material or its physiological function. Conclusions Using simplified alphabetical names may assist in nutrition communication and education of the general public, but dietitians need to be careful to maintain a clear understanding of the proper biochemical distinctions and nomenclatures of the known vitamins, especially when writing for academic publication.
