essential amino acid
n.
An alpha-amino acid that is required for protein synthesis but cannot be synthesized by humans and must be obtained in the diet.

essential amino acid
Etymology: L, essentia, quality
an organic compound not synthesized in the body that is essential for protein synthesis in adults and optimal growth in infants and children. Adults require isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Infants need these amino acids plus arginine and histidine. Cysteine and tyrosine are derived from methionine and phenylalanine, respectively, and are considered semiessential. See also amino acid, nonessential amino acid.

amino acid,
n an organic acid in which one of the CH hydrogen atoms has been replaced by NH2. Amino acids are the building blocks of proteins.
amino acid, essential,
n the group of amino acids that cannot be synthesized by the organism but are required by the organism. They must be supplied by the diet. Isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are essential for adults; these eight plus arginine and histidine are considered essential for infants and children.
amino acid, glucogenic
n the group of amino acids that produce enzymes that may be converted to glucose if necessary.
amino acid, ketogenic
n an amino acid that produces ketone bodies following chemical alteration of its carbon skeleton.

Byline: ANI Washington, Oct 10 (ANI): Human tongue has a receptor that is exclusively activated by glutamate- a non-essential amino acid traditionally used to enhance the taste of many fermented or ripe foods, such as ripe tomatoes or cheese, according to new study.
There are also non-essential amino acids, why they are called non-essential is somewhat of a mystery, since all of them are needed for different biochemical reactions in the body as you will see.
When considering a protein diet, it is important to know that certain foods carry proteins containing essential amino acids which are NOT produced by the body itself but ARE essential to the body's processing of the other 12 non-essential amino acids.
