History

Construction

Tocopherol is a methylated derivative of tocol. The annular part in the structure is a trivial nameChromaneIt is a structure called, and it is attached to this chromanMethyl groupThere are four types, α, β, γ, and δ, depending on the position and presence of. In addition, tocotrienols, which have a large number of double bond portions in the hydrocarbon chain portion of tocopherol, also have activity as vitamin E. TocotrienolsRice oilIt is abundant in vitamins, etc., and shows the same level of antioxidant power in vitro as compared to tocopherol, but 40-60 times higher antioxidant power in cells.[1].. Oral ingestion of tocotrienols in vivostrokeBelieved to prevent related cerebrovascular accidents[2].

The structures of tocopherol and tocotrienol are shown below.

The substitution position of the methyl group and the activity ratio of tocopherol are as follows.

Features

Vitamin E becomes a vitamin E radical by eliminating free radicals, and prevents the chain oxidation of lipids by free radicals. The generated vitamin E radicalsVitamin CSuch asAntioxidantRegenerated to vitamin E[3]

Intake standards

In the past, the required amount was displayed as α-tocopherol equivalent (mgα-TE), butMinistry of Health, Labor and WelfareThe 2010 version of the dietary intake standard established by stipulates a standard intake (AI) and an upper tolerable upper intake level (UL) of α-tocopherol alone. Since most of the vitamin E homologues present in blood and tissues are α-tocopherols, we have established dietary intake standards for vitamin E using only α-tocopherols as an index.[5].

  • Standard amount
    • Adult male (18-29 years) 7 mg / day
    • Adult female (18-29 years old) 6.5 mg / day
  • Maximum amount
    • Adult male (18-29 years) 800 mg / day
    • Adult female (18-29 years old) 650 mg / day

* Vitamin E 1 mg = 1 IU (International unit) Is converted to.

Idiopathic vitamin E deficiency

Vitamin E deficiency has relatively constant clinical symptoms regardless of cause. In some cases, it is almost indistinguishable from neurological symptomsRetinitis pigmentosaThe difference is that it is accompanied by. Basic neurological symptoms are deep and marked deep sensory deficits in the lower extremities, posterior ataxia,DysarthriaAnd the disappearance of the limb tendon reflex. Deep sensory deficits are severe, vibration sensation disappears, and limb joint position sensation is severe. In some patients, retinitis pigmentosa,Babinski sign, Admit tremor.Intellectual disability,Nystagmus, No fasciculations, no autonomic symptoms. HeadMRIThen.cerebellum,BrainstemNo atrophy or abnormal signal area is observed. On spinal cord MRISpinal cordAbnormality may be observed in. Electrophysiological findings show that the median nerveSEPIn N13, the disappearance of cortical potential is observed, but the potential of peripheral nerves is observed. The treatment method is intramuscular injection of vitamin E when malabsorption is accompanied, and when it is not malabsorption, mild oral improvement of neurological symptoms and cessation of progression can be expected.

Excess disease

If taken in excess, bones will be lost and brittleOsteoporosisThe results of animal experiments have been reported to increase the risk of becoming. Excessive intake is not recommended because it is fat-soluble and easily accumulates in the body.[8].

Effect

  • Basic research

radiationBy irradiation ofRed blood cellA hemolytic reaction occurs in theActive oxygenThis is due to the destruction of the membrane due to the reaction of lipid peroxidation. In studies using rats, administration of vitamin E caused hemolysis of red blood cells by radiation andOrganelleIsMitochondria, Microsome,RibosomeThe lipid peroxidation reaction was significantly suppressed.SODShowed a similar effect[9].

Interaction

  • There is an interaction between Vitamin E and Vitamin K1 (phylloquinone), which reduces the amount or activity of Vitamin K1 in the body.
