Indicators
An alkaline earth metal, Magnesium is important for many biochemical functions and reactions; for bone and muscle function, protein and fatty acid formation, activation of B vitamins, blood clotting, insulin secretion, and ATP formation. More than 300 enzymes require magnesium for catalytic action. The adult daily requirement is about 300 mg/day. Magnesium is found in many green plants, vegetables, and seeds; chlorophyll is a magnesium-centered porphyrin compound. Magnesium salts are used for magnesium deficiency supplementation. (NCI04)

Indicators
One of nine essential amino acids in humans (provided by food), Methionine is required for growth and tissue repair. A sulphur-containing amino acid, methionine improves the tone and pliability of skin, hair, and strengthens nails. Involved in many detoxifying processes, sulphur provided by methionine protects cells from pollutants, slows cell aging, and is essential for absorption and bio-availability of selenium and zinc. Methionine chelates heavy metals, such as lead and mercury, aiding their excretion. It also acts as a lipotropic agent and prevents excess fat buildup in the liver. (NCI04)
Indicators
An antimetabolite and antifolate agent with antineoplastic and immunosuppressant activities. Methotrexate binds to and inhibits the enzyme dihydrofolate reductase, resulting in inhibition of purine nucleotide and thymidylate synthesis and, subsequently, inhibition of DNA and RNA syntheses. Methotrexate also exhibits potent immunosuppressant activity although the mechanism(s) of actions is unclear.
Tests
This test measures the amount of methylmalonic acid (MMA) in your blood or urine. MMA is a substance made in small amounts when you digest protein. MMA is needed for metabolism, which is the process that your body uses to change food into energy.

Glossary Term
A sequence of single-stranded RNA, that is 20-25 nucleotides in length, which is transcribed from DNA but is not translated into a protein. This nucleic acid may regulate the transcription or translation of other genes.

Glossary Term
A point mutation occurring within the protein-coding region of a gene, and which codes for a different amino acid than expected.
