Enzymes are proteins that act in the body s chemical reactions by breaking down other chemicals.
ALP is normally present in large amounts in bone and liver. The most severely affected fail to form a skeleton in the womb and are stillborn. The most mildly affected patients may show only low levels of ALP in the blood, yet never suffer bony problems. The x-ray changes are quite distinct to the trained eye. However, it is important that the doctors use appropriate age ranges for normals when interpreting an ALP level.
