Protein is found in abundance in Pea and beans.
Peas (Pisum sativum) and faba beans (Vicia faba) are good sources of plant proteins for being used in human consumption. Pea protein is a relatively new type of plant protein and has been used as a functional ingredient in the global food industry. Pea protein includes four major classes (globulin, albumin, prolamin and glutelin), in which globulin and albumin are major storage proteins in pea seeds.
Many beans and pulses contain lectins, which are proteins that are potentially toxic to humans.
