The role of tachysterol in vitamin D photosynthesis - A non-adiabatic molecular dynamics study [PDF]
Physical Chemistry Chemical Physics 19 (8), 5763-5777 (2017), 2017 To investigate the role of tachysterol in the photophysical/chemical regulation of vitamin D photosynthesis, we studied its electronic absorption properties and excited state dynamics using time-dependent density functional theory (TDDFT), coupled cluster theory (CC2), and non-adiabatic molecular dynamics.

International Journal of Endocrinology, 2013 After absorption from the gut or entry into the circulation from the skin, vitamin D is hydroxylated to 25(OH)D by 25-hydroxylase enzyme in the liver and then to 1α,25(OH)D3 (or calcitriol) by 1α-hydroxylase enzyme in the kidney and in many cells. The hormonal or active form of vitamin D, that is, 1,25(OH)2D3 acts through a nuclear receptor (VDR) to

Conformationally controlled photochemistry studied by trajectory surface hopping [PDF]
arXiv, 2022 This article reviews trajectory surface hopping methods to study conformationally controlled photochemistry. Besides focusing on the linear response time-dependent density functional theory surface hopping method, it reviews the generation of Boltzmann ensembles as starting conditions for photochemical dynamics, the calculation of electronic and ...

Mìžnarodnij Endokrinologìčnij Žurnal, 2021 Despite its historical name, vitamin D is not a vitamin at all but a hormone that, when activated, is a metabolically active steroid fat-soluble hormone that acts on cellular receptors.
