1. Abnormal hemoglobin
Hemoglobin molecule with a different shape due to an altered amino acid sequence (ultimately caused by an altered DNA base sequence), such as in the inherited disease sickle-cell anemia .

2. Alanine
One of the twenty naturally occurring amino acid s. Has the following chemical characteristics: pKa1-2.35, pKa2-9.69, pI-6.02, Water Solubility (30deg C)-15

3. Alkaloids
A class of over 3000 known nitrogen-containing compounds (such as morphine, caffeine, cocaine and nicotine ) that are typically basic ( pH over 7) and are produced by plants but have strong physiological effects on animals (including humans). They are synthesized from amino acid precursors such as tryptophan and tyrosine .

4. Alpha ketoglutarate dehydrogenase
This is an enzyme that acts in the alpha-ketoglutarate pathway, an intermediate pathway in the Krebs cycle in which amino acid derivatives enter the cycle. Alpha ketoglutarate dehydrogenase serves to convert NADH + succinyl-CoA + CO2 into alpha-ketoglutarate + CoA + NAD+.

5. Amber codon
The nonsense codon UAG, one of three codons which, instead of coding for an amino acid, signals that the translation of mRNA into a chain of amino acid s should stop.

6. Amber mutation
A mutation from a codon which codes for an amino acid into the amber codon UAG, which normally signals that the translation of mRNA into an amino acid chain should stop. The mutation causes the amino acid chain to stop forming before it is actually completed.

7. Amber suppressor
A tRNA molecule which suppresses amber mutation s because it has mutated to recognize the amber codon UAG (which normally signals that the translation of mRNA into an amino acid chain should stop) as a signal for inserting whatever amino acid it carries into the chain. As a result, it can prevent the amino acid chain from ending before it is completed.

8. Ambiguous codon
A codon that codes for more than one amino acid .

9. Amide linkage
This is a carboxylic acid containing an amino group (-NH2). In an alpha amino acid, the amino group is attached to the carbon atom directly beside the carboxyl group.

10. Amino acid
Any of a class of 20 molecules that are combined to form protein s in living things. The sequence of amino acids in a protein and hence protein function are determined by the genetic code .
