Yes. In particular the essential amino acid Lysine is deficient
in plant proteins. Lysine can prevent glyco-sylation in ageing
and (IIRC) is important for strong muscles and immune function.
In talking with vegans I am always surprised that so frequently
they are unaware of this possible deficiency. If the vegan
diet is restricted (perhaps to lose weight) lysine deficiency
is almost inevitable.
