alpha tocopherol/ダイズ

Soybean seeds are an important source of dietary tocopherols, but like seeds of other dicotyledonous plants, they contain relatively little alpha-tocopherol, the form with the greatest vitamin E activity. To evaluate potential effects of environmental stress during seed maturation on tocopherols,

The content of [alpha]-tocopherol ([alpha]T) in isolated soybean (Glycine max, var Hood) embryonic axes was measured upon germination. Dry, high-vigor axes contained 1.2 [plus or minus] 0.1, nmol/axis and after an increase during the initial 6 h of imbibition, there was a decline to 1.0 [plus or

Gamma-tocopherol methyltransferase (γ-TMT) converts γ-toc to α-toc-the rate limiting step in toc biosynthesis. Sequencing results revealed that the coding regions of γ-TMT1 and γ-TMT3 were strongly similar to each other (93% at amino acid level). Based on the differences in the

γ-Tocopherol methyltransferase (γ-TMT) (EC 2.1.1.95) is the last enzyme in the tocopherol biosynthetic pathway and it catalyzes the conversion of γ-tocopherol into α-tocopherol, the nutritionally significant and most bioactive form of vitamin E. Although the γ-TMT gene has been successfully

The consumption of soybean is limited worldwide, despite being highly nutritious and having versatile uses due to the presence of grassy, beany and rancid off-flavour. The lipoxygenase-2 (LOX-2) is the key enzyme responsible for the production of volatiles released from the beans, which cause

The vitamin E family includes tocopherols and tocotrienols, which are essential lipid-soluble antioxidants necessary for human and livestock health. The seeds of many plant species, including maize, have high gamma (γ)-tocopherol but low alpha (α)-tocopherol contents; however, α-tocopherol is the

BACKGROUND Improvement of α-tocopherol content is an important breeding aim to increase the nutritional value of crops. Several efforts have been conducted to improve the α-tocopherol content in soybean [Glycine max (L.) Merr.] through transgenic technology by overexpressing genes related to

Drought stress-induced antioxidative defense responses were studied in seven soybean (Glycine max (L) Merr.) cultivars PUSA 9712, LSB 1, JS 335, ADB 22, NRC 37, DSB 20, and MAUS 61, respectively. Drought stress was imposed by withholding irrigation till the leaf water potentials reached -1.0, -1.5,

γ-Tocopherol methyl transferase (γ-TMT) (EC 2.1.1.95) is the key enzyme of the tocopherol biosynthetic pathway that determines the α-tocopherol concentration in plants. The overexpression of γ-TMT has been a successful approach for α-tocopherol enrichment of most plants including soybean. The

The scope of application EFSA-GMO-DE-2012-111 is for food and feed uses, import and processing of genetically modified (GM) soybean SYHT0H2 in the European Union. Soybean SYHT0H2 was developed to confer tolerance to the herbicidal active substances mesotrione and other p-hydroxyphenylpyruvate

We investigated how soyasaponins (SS), which had been isolated from soybeans (Glycine max Merrill, seeds), influenced lipid peroxidation. The in vivo reduction in hepatic lipid peroxidation in mice intraperitoneally injected with total soyasaponins (TSS) was comparable to that which has been

GmTMT transgenic maize is a genetically modified maize plant that overexpresses the γ-tocopherol methyltransferase (γ-TMT) from Glycine max (Gm). The γ-TMT gene was introduced into maize line Zhen58 to encode the GmTMT2a protein which can convert γ-tocopherol into α-tocopherol. Overexpression of

BACKGROUND The most common complaints during climacteric are vasomotor symptoms. A circadian rhythm has been observed when hot flashes start; however, not much information is available in this field. OBJECTIVE To analyze whether the time (morning/evening) of administration of a compound containing

Materials with a particle size less than 100 nm are classified as nano-materials. The physical and chemical properties of nano-materials can vary considerably from those of bulk materials of the same composition. Silicon (Si) still fails to get recognized as an essential nutrient for plant growth
