| 摘要 |
The invention relates to a composition for oral or parenteral use, characterized in that the composition contains free L-glutamine and also at least one derivative of L-glutamine and optionally at least one precursor to L-glutamine, the composition being prepared aseptically and freeze-dried in powder form and radiation-sterilized, or in the form of a solution which is stored at low temperature, preferably in deep-frozen form. The derivative preferably consists of peptides, such as glycyl-L-glutamine and/or L-alanyl-L-glutamine, and the precursor may consist of alpha-keto-glutaric acid or the salt/derivative thereof. The derivative may also consist of N-acetyl-L-glutamine. The composition may also contain other nutrient components, or technical auxiliary substances, such as carbohydrates, sugar alcohols, vitamins and/or amino acids, preferably in freeze-dried form. The invention also relates to the production of the composition and to a method of preparing a nutrient solution. |
