In pulses, limiting amino acids are

In pulses, limiting amino acids are Methionine and Tryptophan.
Pulses contain approximately 21 - 25% protein; however have a limiting amount of essential amino acids such as methionine, tryptophan and cystine.
A limiting amino acid is an essential amino acid that is present in a certain food in the lowest amount, which prevents protein synthesis in the body beyond the rate at which that amino acid is available.
The protein content and amino acid composition vary with the variety, germination, environment and application of fertilizers.
