What foods besides watermelon are good sources of the nutrient citrulline?
http://en.wikipedia.org/wiki/Citrulline#Sources Sources Citrulline in the form of citrulline malate is sold as a performance-enhancing athletic dietary supplement which is said to reduce muscle fatigue. The rind of watermelon (Citrullus lanatus) is a good natural source of citrulline. The organic compound citrulline is an α-amino acid. Its name is derived from citrullus, the Latin word for watermelon, from which it was first isolated in 1930.[1] It has the idealized formula H2NC(O)NH(CH2)3CH(NH2)CO2H. It is a key intermediate in the urea cycle, the pathway by which mammals excrete ammonia. Sources: http://www.healthvitaminsguide.com/aminoacids/citrulline.
