Metabolic diseases

What are the causes?

Metabolism is a very complex process that occurs in small steps, each one being regulated by an enzyme (complex protein). Some involve anabolism (the build-up of essential components of the body) and others involve catabolism (the break down of essential components of the body). As a consequence of a genetic defect the enzyme may be completely missing or have worked inefficiently. The enzymes are usually grouped in pathways and if there is a blockage then the compound accumulates before the block and the substance that is normally formed will be reduced.
