1. -ase
A suffix which indicates that the word is the name of an enzyme , which is a type of protein that catalyzes biological or biochemical reactions. For example, " cellulase " or " polymerase ".

2. 1,4-glucan branching enzyme (brancher, branching enzyme, Q enzyme)
An enzyme which makes new branches in glycogen or amylopectin molecules by moving a 1,4-D- glucan chain on the molecule to a primary hydroxyl group (an -OH group) on the same molecule.

3. 5-fluorouracil (5-FU)
An anti- cancer agent similar in structure to the nitrogenous base thymine , which inhibits the enzyme dihydrofolate reductase (DHFR) and thus nucleotide synthesis, so that it is particularly harmful to rapidly growing cells such as in tumors .

4. 5-hydroxymethylcytosine
A nucleotide base derived from cytosine which is used by the bacteriophage T4 in place of cytosine in its DNA . The substitution protects the bacteriophage from its own nuclease enzyme s (enzymes which cut apart DNA).

5. Abomasum
The fourth stomach of the cow. The abomasums of suckling calves are used as a source of rennet, a rennin -containing commercial enzyme preparation used to make cheese.

6. Acetyl coA synthase
This enzyme is found in bacteria and plants; it catalyzes the reaction in which acetate enters metabolic pathways and forms acetyl coenzyme A .

7. Acetyl CoA
An intermediate compound formed during the breakdown of glucose by adding a two-carbon fragment to a carrier molecule (Coenzyme A or CoA).

8. Acetyl coenzyme A (acetyl CoA)
This coenzyme plays a huge role in intermediary metabolism, in which cells synthesize, break down or use nutrient molecules for energy production, growth, etc.

9. Acetyl reduction assay (acetylene reduction assay)
A technique for measuring the nitrogen fixation activity in photosynthetic organisms. It uses a flame ionization detector and a gas chromatography apparatus to determine the reduction of acetylene to ethylene by the enzyme nitrogenase .

10. Acetylcholinesterase
An enzyme that breaks down unused acetylcholine in the synaptic cleft (the space between neurons); this enzyme is necessary to restore the synaptic cleft so it is ready to transmit the next nerve impulse.
