The molecular structure of vitamins makes them easily degradable under various conditions such as temperature, pressure, and pH. It is necessary to understand determine the stability during processing food products ensure their presence at time consumption. In this study, degradation added was assessed before after heat treatments manufacturing products. Vitamins interest were quantified by HPL...

The main purpose of this study in order to estimate fat soluble vitamins contents Mackerel fillets from the northeastern coast of Tunisia. Retinol, α-tocophérol and cholecalciferol were analyzed using HPLC system. The experimental procedure used for extraction consisted on saponification, normal phase separation with UV and fluorescence detection for tocopherol and retinol. While cholecalcifero...

BACKGROUND The role of vitamins in the combat of disease is usually conceptualized as acting by modulating the immune response of an infected, eukaryotic host. We hypothesized that some vitamins may directly influence the growth of prokaryotes, particularly mycobacteria. METHODS The effect of four fat-soluble vitamins was studied in radiometric Bactec® culture. The vitamins were A (including ...

Mulberry (Morus spp., Moracecae) is a notable medicinal and multi-functional plant. Distinct mulberry types are spread in subtropical, temperate tropical areas all over the world. leaves carry number of bioactive compounds with it along various pharmacological effects. It magnificent origin nutrients, phytochemical been proven as nutraceutical. have wide range effects having bacteriostatic, ant...

A previous report from this laboratory (1) demonstrated the existence of two water-soluble vitamins needed by the chick; namely, vitamin Blo, essential for proper feather formation, and vitamin B11, necessary for growth. Both of these vitamins, present in a liver concentrate (Super Filtrol eluate), were shown to be distinct from “folic acid”l which was also present in the liver concentrate. All...

Deficiencies in vitamins and other nutrients are common following the Roux-en-Y gastric bypass (RYGBP), biliopancreatic diversion (BPD) and biliopancreatic diversion with duodenal switch (BPDDS), and may become clinically significant if not recognized and treated with supplementation. This paper presents a review of the current literature and evidence of the most commonly deficient vitamins and...

Folates are soluble B9 vitamins with essential functions in all kingdoms of life—both in organisms that produce these vitamins de novo (fungi, plants, and most microorganisms) and in those that do not (animals). As essential cofactors in one-carbon transfers, different folate species mediate the biosynthesis of multiple biomolecules, including nucleic acids, amino acids, and lipids. Folates als...

The advances made in the purification of the vitamins have provided an improved method of approach toward the study of the number, as well as nature, of the essential food factors. Because of the uncertain composition of the vitamin B complex, it is as yet very difficult to test for additional water-soluble components of the ultimate purified diet. The fat-soluble group, however, appears less c...

Background: Premature ovarian insufficiency (POI) is a major concern in women's health. It hypothesized that deficiency fat-soluble vitamins might result POI; however, this relationship has not been extensively evaluated. Objectives: This systematic review was designed to elucidate the between vitamin serum levels and POI. Methods: conducted on international databases, including Scopus, Nationa...

According to Stedman's Medical Dictionary, a vitamin is 'one of a group of organic substances, present in minute amounts in natural foodstuffs, that are essential to normal metabolism.' As defined, vitamins are present in very small quantities in most foods and it is this fact that leads to the manufacture of vitamin supplements for dogs, cats, and people. Not only are vitamins naturally presen...
