Soybean seeds are rich sources of vitamin E tochromanols with typical concentrations of 250–350 μg/g seed weight (Almonor et al., 1998; Van Eenennaam et al., 2003). Vitamin E tocochromanols occur almost exclusively as tocopherols in soybean seeds, and ~60% is in the γ-tocopherol form, with the remainder of the tocopherol in the …
Tocopherols (vitamin E) are lipophilic antioxidants synthesized by all plants and some algae and cyanobacteria. The four types of tocopherols synthesized (α, β, γ, and δ) differ only in the number and positions of methyl substituents on the chromanol ring. All tocopherols are amphipathic molecules, … See more
Maternal serum vitamin E were measured from blood samples collected in each trimester. Logistic regressions were performed to analyze the association between maternal vitamin E levels and outcomes. The median levels of maternal vitamin E increased from the first (10.00 mg/L) to the third (16.00 mg/L) trimester.
The aim of this study was to evaluate the effect of dietary supplementation with hemp seed oil (HSO) on the lipid metabolism, through the plasma lipid profile, liver function and concentrations of ...
Clinical uses: Humans with defects in the TTPA gene (encoding α-TTP) have extraordinarily low (1/100 of normal) plasma vitamin E concentrations, but if they are given vitamin E supplements, plasma concentrations normalize within hours; if supplementation is halted, plasma vitamin E concentrations decrease within days to deficient levels. A …
The oil content of sesame seeds ranges from 37% to 63%, depending on the cultivar and the growing season ... Studies have shown that γ-tocopherol is the major form of vitamin E in sesame seeds, ... They observed the course of plasma concentrations of diclofenac over time in rats given sesamin for 3 days after …
Although the specific nutritional requirements and normal values for selenium and vitamin E have not been reported in mules, 1 study of a small, varied population of donkeys identified similar plasma vitamin E concentrations and substantially lower plasma selenium concentrations compared to horses. 39 It is unclear, however, if whole blood ...
Total B vitamin concentrations in cotyledon samples were lower in samples from 2018 versus samples from 2020, while total B vitamin concentrations in seed coats showed greater variability and a larger range of concentrations in samples from 2018, while samples from 2020 displayed more consistent total concentrations.
Variability of vitamin E content in pumpkin seeds (Cucurbita pepo L.) Received: 4 July 1995 ... nant tocopherol in pumpkin oil seed, is in the range of 41 to 620 mg/kg. The range of concentrations of c~-toco- pherol is 0 to 91 mg/kg. Both fi- and 3-tocopherol are 277 very low, but, sporadically can reach 16 mg/kg and ...
A concentration-function approach to vitamin C (ascorbate) has yielded new physiology and pharmacology discoveries. To determine the range of vitamin C concentrations possible in humans, pharmacokinetics studies were conducted. They showed that when vitamin C is ingested by mouth, plasma and tissue concentrations …
Sesame has a wide range of adaptation and a remarkably large number of varieties have been developed suiting to diverse agroclimatic conditions. ... Among the vitamins in the sesame seed, the presence of vitamin E is very interesting in relation to the effectiveness ... the α-and δ-tocopherols are at relatively low concentrations and vary ...
Micronutrient intake is vital for maintaining health and preventing diseases throughout life. While whole foods should be the primary source of micronutrients, supplementation is necessary in certain cases. Both deficiencies and excess intake of micronutrients can have adverse effects. Common deficiencies include vitamin A, folate, …
Tocotrienols, primarily in the δ- and γ-forms, accounted for ∼85% of the total vitamin E in these seeds (Table 1, Fig. 3). In addition, total tocopherols were increased by ∼two-fold and δ-tocopherols were increased by > 40-fold compared to concentrations in wild-type seeds. (Table 1). Normal phase separation showed of the total <1% were ...

Vitamin E is thought to function primarily as a chain-breaking antioxidant that prevents the propagation of lipid peroxidation. Overt deficiency is very rare, seen only in individuals unable to absorb the vitamin or with inherited abnormalities that prevent the maintenance of normal blood concentrations. Thus, current dietary patterns appear to provide …
