[Intensity of label incorporation from [1,4-14C]putrescine into homocarnosine in the brain of rats of various ages].
Intensity of 14C incorporation from the [1.4-14C]-putrescine to the homocarnosine and homocarnosine content in the brain of 1-, 7-, 14-, 21-day and adult rat were investigated. It is shown that dynamics of 14C incorporation from 1.4-14C-putrescine to the homocarnosine in the brain of rats of different age does not correlate with dynamics of homocarnosine content increase. The most significant activity of label incorporation from 14C-putrescine to the homocarnosine takes place in the brain of 1-, 21-day animals and adult rats.
