carbon dioxide. Other methods that not only help to preserve food, but also add flavor, include pickling, salting, smoking, preserving in syrup or alcohol, sugar crystallization and curing.
As the preceding paragraphs say, many kinds of food preservation technologies are around for preventing foods from the undesirable results. Specifically this report deals with the methods that inhibiting the

1. Inconsistent efficiency
Efficiency sharply drops when it works for long time.
It happens as nutrients for microorganisms are insufficient.
2. Unequal growth of microorganisms
Efficiency decreases, hard to handle when factors change suddenly

Bioethanol can be produced by starch from algae through hydrolyze, pre-treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free comp

The same reaction that inhibits fatty acid synthesis promotes fatty acid oxidation and consequently ketogenesis.
Long-chain fatty acid molecules that reach the liver can be either oxidized or esterified and exported to adipose tissue as the triglyceride.
To be esterified, fatty acids must remain in the cytosol, and to be oxidized they must enter the mitochondria.

Despite the diverse chemical structure of aspirin-like drugs, the antinociceptive effect of NSAIDs is mainly due totheir common property of inhibiting cyclooxygenases involved in the formation of prostanoids. Prostanoids areformed by most cells and act as autocrine and paracrine lipid mediators. They are n
and HupL subunit is formed and functional in heterocysts.
Based on present research findings, it can be seen that hydrogen production in cyanobacteria can be increased by blocking the function of uptake hydrogenase.
2) Limitation of Hydrogen Production
When the 9.5kb element is excised, the heterocyst form of the cell will produce uptake hydrogenase. Therefore we must inhibit the 9.5k

Carbon에 붙어 있는 +NH3 의 Positive Charge가 COOH의 proton과 Repulsion이 작용하기 때문으로 보인다. 따라서 평형이 COOH -> COO- 의 방향으로 촉진되어 pK'가 낮아지게 된다.
