| 摘要 |
The present invention provides soluble and/or stable sources of tyrosine, cysteine and glutamine for use in total parenteral nutrition (TPN), as well as a gradual release source of glutamic acid. In particular, these sources are gamma-glutamyltyrosine ( gamma -GluTyr), gamma-glutamylcysteine derivatives ( gamma -GluCys) and gamma-glutamylglutamine ( gamma -GluGln). This invention provides TPN formulations, and methods of formulating and using such solutions containing gamma -GluTyr, gamma -GluCys and/or gamma -GluGln to provide adequate nutritional levels of tyrosine, cysteine or glutamine during TPN. |
