What are biologically complete proteins?
|Proteins are made up of many small units called
Amino Acids. Each molecule of protein may contain millions of
such Amino Acids. There are about twenty amino acids required
by the human body. Of these, twelve can be synthesised in the
human body itself. These are called Non-essential amino acids.
The rest of the amino acids have to be supplied in the diet.
These are called Essential amino acids.
Proteins which lack one or more of the essential
amino acids are called biologically incomplete proteins. Proteins
containing all the essential amino acids in them are called biologically
An individual eating a diet consisting of biologically
incomplete proteins will eventually develop deficiency of the essential
amino acids, thereby leading to various ailments. The resulting
disease can be corrected by giving a biologically complete protein,
the egg protein, for example.
Mixed diets with varied food components provide
the best amino acid combination in their protein constitution.
