Question

Standard neonatal parenteral amino acid solutions differ from standard adult parenteral amino acid solutions by having a higher content of

1: cysteine.
2: phenylalanine.
3: taurine and tyrosine.
4: methionine and glycine.

Answer 1

Standard neonatal parenteral amino acid solutions differ from adult solutions by having a higher content of taurine, tyrosine, and cysteine to meet infants' unique requirements.

Step-by-step explanation:

The question pertains to the differences in amino acid content between standard neonatal and adult parenteral amino acid solutions. Neonatal solutions have a different amino acid composition to meet the unique metabolic and developmental needs of infants. In particular, neonatal solutions typically have a higher content of taurine and tyrosine, as well as cysteine, which is important due to its role in antioxidant defense and the synthesis of proteins, while infants may have a limited capacity to synthesize it. Therefore, the correct answer is that standard neonatal parenteral amino acid solutions differ from standard adult parenteral amino acid solutions by having a higher content of taurine and tyrosine, as well as cysteine.
