Protein isn't monolithic: there are 20 amino acids which are found in different proportions. Plants, specifically, often have less leucine than animals, which is an important signalling molecule that feeds into mTOR as well as protein synthesis regulation. https://www.physiology.org/doi/full/10.1152/ajpendo.00153.2003 https://www.physiology.org/doi/full/10.1152/ajpendo.00153.20... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3322509/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3322509/ This doesn't make plant protein 'bad', but it is something to consider, especially if using a plant-based diet.
