The influence of Ultraviolet (UV) irradiation on collagen in the presence of vitamin C (ascorbic acid) has been investigated by microcalorimetric method. It has been observed the gradual decrease of collagen molecule destabilization whereas the vitamin C concentration in the solution increases. At some ratio of vitamin C and collagen in the solution the influence of UV irradiation has not been observed any more. Taking into consideration that vitamin C is a protective system against the appearance of free radicals our results confirm the assumption, that the collagen molecule destabilization, caused by the influence of UV irradiation, is the result of free radicals presence in the solution [1]. At the same time the real molecular mechanisms of vitamin C action as a protective system are revealed.
