[Kinetics and action mechanism of vitamin D3 in the process of lipid and blood plasma oxidation in model system].

Kinetics and mechanism of vitamin D3 action were investigated in the process of initiated oxidation of various modeling systems in comparison with activity of various antioxidants such as: alpha-tocopherol, dibunol, alpha-tocopheryl quinone, ubiquinone Q10, philloquinone and beta-carotene. Vitamin D3 addition increased initial and maximal rates of oxygen consumption. The length of circuits, value of a kinetic parameter k2/square root k6, describing oxidability of system as a whole was also increased.
