Gelatine ist eine sehr minderwertige Proteinquelle.
Die Biologische Wertigkeit beträgt 0, da ihr alle essentiellen Aminosäuren fehlen!

A more extreme example would be the combination of gelatine (which contains virtually no tryptophan and thus has a PDCAAS of 0) with isolated tryptophan (which, lacking all other essential amino acids, also has a PDCAAS of 0).
