Determination of N-acetyl-l-glutamine in urine by HPLC
1986
The determination of N-acetyl-l-glutamine (AC-GLN) in urine of rats after derivatization with xanthydrol by HPLC is described. The urine samples were collected from two groups of rats, one group fed normal nutrition, the other treated with AC-GLN. About 5 mM/l AC-GLN was detected in urine of untreated animals, whereas the excretion of the other group was in the range of 50 mM/l corresponding to about 50 wt.-% of the given AC-GLN.
Risk Assessment of "Other Substances" – L-Glutamine and L-glutamic Acid
2020
The Norwegian Scientific Committee for Food Safety (Vitenskapskomiteen for mattrygghet, VKM) has, at the request of the Norwegian Food Safety Authority (Mattilsynet; NFSA), assessed the risk of "other substances" in food supplements and energy drinks sold in Norway. VKM has assessed the risk of doses given by the NFSA. These risk assessments will provide the NFSA with the scientific basis for regulating the addition of “other substances” to food supplements and other foods.
 "Other substances" are described in the food supplement directive 2002/46/EC as substances other than vitamins or minerals that have a nutritional or physiological effect. They are added mainly to food supplements,…
