Metabolism refers to all chemical reactions that occur in the body. The majority of inherited metabolic disorders are due to defects of single genes that code for enzymes that facilitate conversion of various substances into others. In most of the disorders, problems arise due to accumulation of substances which are toxic or interfere with normal function, or to the effects of reduced ability to synthesize essential compounds.
