Usage Note
- Amino acid content is in milligrams, protein value in grams, and are measured per
100g of food weight.
- Click on column header to sort foods by name or by column's content.
- Amino-Acid Score:
- The score is the ratio of the amino acid in the food's protein over the same amino
acid in the reference protein expressed in percentage.
- This score is for determining the limiting amino acid in a food item. A score below
100 indicates that a food's protein is incomplete. However, a score higher than 100 for a particular
amino acid does not necessarily mean that a food's protein is complete. Scores of
other essential amino acids of the food also have to be 100 or higher for its protein to be
considered complete.
- The limiting amino acid of a food is defined as the essential amino acid present
in the lowest amount compared to a reference protein or to human requirements.
Amino Acids
Amino acids are organic compounds that combine to form proteins. When proteins are
digested, amino acids are left. The human body requires a number of amino acids
to grow and breakdown food.
Amino acids are classified into two groups: essential and nonessential amino acids.
- Essential amino acids cannot be made by the body and must be supplied by food. These
include leucine, lysine, tryptophan, etc. Sources of essential amino acids include
milk, cheese, eggs, certain meats, vegetables, nuts, and grains.
- Nonessential amino acids can be made by the body from the essential amino acids
or normal breakdown of proteins. They include aspartic acid, glutamic acid, and
glycine, etc.
Complete Protein
A complete protein (or whole protein) is a source of protein that contains
an adequate proportion of all nine of the essential amino acids necessary for the
dietary needs of humans or other animals. Some incomplete protein sources may contain
all essential amino acids, but a complete protein contains them in correct proportions
for supporting biological functions in the human body.
Threonine
As an essential amino acid, threonine is not synthesized in humans, hence we must
ingest threonine in the form of threonine-containing proteins. In plants and microorganisms,
threonine is synthesized from aspartic acid via α-aspartyl-semialdehyde and homoserine.
