Which is an incomplete animal protein?
Incomplete proteins are missing, or do not have enough of, one or more of the essential amino acids, making the protein imbalanced.
- Most plant foods (such as beans and peas, grains, nuts and seeds, and vegetables) are incomplete protein sources.
- Gelatin has no tryptophan (an essential amino acid), very low levels of Branched-chain amino acid and high levels of non-essential amino acids, so it is an outlier in the world of animal proteins.
Good Luck!
Dear Amaya,
The incomplete protein is gelatin or collagen.
