| Abstract: | By the method of differential scanning calorimetry it was shown that the addition of arachidonic acid to photoreceptor membranes is accompanied by concentration-dependent shift of thermograms curve of rhodopsin value. Addition of tocopherol to photoreceptor membranes prevents the turbulent effect of the fatty acid on opsin and rhodopsin. The obtained data are discussed from the point of view of membrane protective properties of tocopherol. |
