1) prpp combines with glutamine (done by enzyme prpp glutamyl amidotransferase
or gpat - note: gpat is inhibited when gmp is high, and can be activated by prpp)
2) synthesis continues until production of imp, which can be used to generate amp
and gmp
(high levels of gmp inhibits conversion of imp->gmp;
high levels of amp inhibits conversion of imp->amp)
the synthesis of cysteine
the liver and requires ATP
fatty acids synthesized in the liver
