Question

For neonates, which of the following amino acids should be added separately to parenteral nutrition solutions due to solubility concerns?

1: Glycine
2: Cysteine
3: Methionine
4: Phenylalanine

Answer 1

Cysteine should be added separately in parenteral nutrition solutions for neonates to address solubility concerns and ensure a stable formulation.

Step-by-step explanation:

For neonates, cysteine should be added separately to parenteral nutrition solutions due to solubility concerns. Cysteine is a hydrophilic amino acid that can have solubility issues when used in concentrated solutions, such as those required for parenteral nutrition in neonates. Because cysteine may promote stability and solubility of other amino acids in the solution, its separate addition helps in creating a more stable and soluble parenteral nutrition formulation.
