Unlike the human fetus late in gestation, the fetal rhesus monkey may have considerable activity of hepatic cystathionase, and brain and renal cystathionase have attained mature activity. The term rhesus monkey fetus, like the human fetus, accumulates methionine, but does not accumulate cystine from the mother against a fetal: maternal concentration gradient. Studies with 35S-methionine and 35S-cystine measuring incorporation into various tissues confirm the ability of the fetus to metabolize methionine and cystine to inorganic sulfate. However, incorporation of 35S-methionine into 35S-cystathionine in the fetal liver suggests that the ability to cleave cystathionine is still diminished. |
