I am trying to work out the nitrogen and energy content of a product. I only have info that nitrogen content in protein range from 13 to 19% with 16% taken as the average and hence conversion factor of 6.25. But I was wondering if anyone has more info on the specific conversion factor for arginine amino acid to nitrogen. Thanks.

Thanks Mushtaq Ahmad for the response but I can't open the link you attached. Please kindly assist. Thanks.
Arg is C6H14N4O2 with MW=174.20g/ml therefore its nitrogen content is 4×14 and its nitrogen percentage is (100×4×14)/174.20=32.1469%. Therefore conversion factor for Arg is 100/32.1469=3.11. Based on its formula you can guess it quickly 6.25/2=3.125.
Perfect. Thank you so so much Isaac Karimi. Very helpful indeed.
