A group of proteins that contain the 9 essential amino acids from animal  sources are called complete proteins.

Explanation:

Complete proteins have in their structure an adequate proportion of the 9 essential amino acids, which come predominantly from food sources of animal origin.

Essential amino acids are so called because the human organism does not produce them and they must be ingested in the daily diet. These amino acids are:

- Phenylalanine

- Histidine

- Isoleucine

- Leucine

- Lysine

- Methionine

- Threonine

- Tryptophan

- Valine

Vegetables only provide complete proteins if they are associated with different types in the diet. Essential amino acids are necessary for the normal functioning of the organism.
