tyrosine and taurine
45
what 3 amino acids are given in lower amounts than adults
phenylalanine, methionine, glycine
46
_______ amino acid is not part of a standard infant PN amino acid solutions but can be added separately to lower the pH to optimize calcium and phosphorous solubility
cysteine
47
the amino acid cysteine is not part of standard pediatric amino acid solutions in PN but can be added for what benefit
optimizes calcium and phosphorous solubility by lowering the pH
