Amino acids are the building blocks of proteins and form part of our diet. In order to break down or change (metabolise) the amino acids in our body, special proteins called enzymes are needed. If there is a change or mutation in the gene coding for an enzyme, the normal metabolism gets blocked and the amino acid builds up in the body and may

Metabolomic analysis of urinary amino acids (AAs) from patients with bladder cancer was performed by gas chromatography–mass spectrometry. The βaminoisobutyric acid (P < ) and pyroglutamic acid (P < ) levels among 21 AAs had relatively low Pvalues in the cancer group. The distorted star pattern of the cancer group was different from the heneicosagonal shape of the control mean.

Organic Acid Disorders:. Organic acid disorders (OAs) are a group of rare inherited conditions. They are caused by enzymes that do not work properly. A number of enzymes are needed to process protein from the food we eat for use by the body. Problems with one or more of these enzymes can cause an organic acid disorder.
