Tocopherols in Micro-organisms [PDF]

open access: yesNature, 1959
ALTHOUGH the tocopherols, and in particular α-tocopherol, are widely distributed in Nature, they have not so far been identified in micro-organisms. The only micro-organism that has been adequately studied is bakers' yeast, which has been found to contain no tocopherol, although it contains another substance with vitamin E-like activity1.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

open access: yesBMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Content of fatty acids, vitamin E and carotenoids in milk and herbage as affected by sward composition and period of grazing [PDF]

open access: yes, 2011
The quality of organic milk is affected by feed composition, and especially the high use of legumes has been identified as the reason for high levels of polyunsaturated fatty acids, carotenoids and tocopherols in organic milk. Four different pastures

Improving Antioxidants and Physicochemical Properties of Wild Rice Noodles by Fortification With Carrot Powder

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Wild rice (WR), a nutritious cereal rich in phytochemicals, remains underutilized despite its health benefits. This study explored deep purple (DP), purple sun hybrid (PSH), purple haze (PH), cosmic purple (CP), and vistaric sky blue (VSB) carrot powders as fortificants in WR noodles at 10%, 20%, and 30% levels in ...

Asymmetric Reduction of Unactivated Alkenes

open access: yesChemistry – A European Journal, EarlyView.
Unactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...
