Total free amino acid levels in adult and senescent rat liver.
The total free amino acid content per gram of liver wet weight does not differ significantly between adult and senescent female rats, being 28.8 +/- 3.3 mumol in adult (13-17 months) and 26.2 +/- 2.2 mumol in senescent (23-29 months) animals. This is the first study in which these two age-groups of rats have been so compared. These results combined with a survey of the literature show that amino acid levels in rat liver do not change much, if at all, throughout the lifespan of the animal.
