Purchase salicylates in small amounts when used on an occasional basis. Keep the container tightly closed at all times because salicylates deteriorate rapidly when exposed to air, moisture, and heat. 

The spectral variations caused by the interference phenomena become relevant when a food contains tightly adjoining dense structures like feathers, fish scales, or the shells of crustaceans.

Place the acid ampule into a rubber contraceptive or toy balloon, along with a few spoonsful of sugar-chlorate mixture and one nonelectric blasting cap. Then tie the opening of the rubber container tightly. See Figure 17.

S-adenosylmethionine is also a biological methyl group donor. The product of its methyl transferase reactions is S-adenosylhomocysteine. This product is further degraded by S-adenosylhomocysteine hydrolase, an enzyme that contains tightly bound NAD+, to form homocysteine and adenosine. 

The hydroxyethylthiamine pyrophosphates are potent nucleophiles and may add to carbonyl compounds to form carbon-carbon bonds. A good illustration of carbon-carbon bond making and breaking occurs in the reactions of transketo-lase. The enzyme contains tightly bound thiamine pyrophosphate and shuttles a dihydroxyethyl group between D-xylulose 5-phosphate and D-ribose 5-phosphate to form D-sedoheptulose 7-phosphate and D-glyceraldehyde 3-phosphate (equations 2.55 and 2.56). 

Zinc proteases are metalloenzymes containing tightly bound zinc examples are carboxypeptidases A and B, collagenase, and thermolysin. The zinc atom is bound to the imidazole moiety of two histidines and the carboxylate of Glu the fourth ligand is a molecule of H20. 

There are numerous instances in this handbook of laboratory waste bottles, or industrial waste drums, slowly pressurising and then bursting. In the latter case, sometimes the consequences are fatal. It is unwise to seal a freshly filled waste container tightly, ideally they should be left slightly less than air-tight and only sealed immediately before transport for final disposal. 

Liquids formed from covalently bonded solids are different from ionic-bond solids in another way as well. Covalently bonded liquids do not contain free-floating charged particles. Instead, they contain tightly-bonded, self-contained, neutral molecules. As a result, a liquid produced from a covalently bonded solid does not conduct electricity well at all. These liquids are good insulators. 

Soluble in 350 parts water miscible with alcohol, ether, and oils. It reduces ammoniacal silver nitrate, but not Fehling s solution. Keep container tightly closed and protected from light.1...

PolyPs and PHB have been found to be associated with ion-conducting proteins such as the human erythrocyte Ca2+-ATPase pump (Reush et al, 1997) and the Streptomyces lividans potassium channel (Reusch, 1999b). Some enzymes of PolyP metabolism, such as polyphosphate glucokinase (Phillips et al, 1999) and yeast high-molecular-weight exopolyphosphatase (Andreeva et al, 2001, 2004), can contain tightly bound PolyP. 

Pyruvate carboxylase is an allosteric enzyme being activated by its effector, acetyl-CoA. The enzyme contains tightly bound Mn2+ ions, and a covalently attached prosthetic group, biotin. When the mitochondria are in a high-energy state, the concentrations of acetyl-CoA and ATP are relatively high, so the modulator of the enzyme and a source of energy are both available. The oxaloacetate is then converted within mitochondria to malate ... 

Note For all reference standards, do not dry before use, and keep the containers tightly closed and protected from light. Determine the water content of the USP Fumaric Acid Reference Standard titrimetrically before use, and make the necessary correction in preparing the Standard Preparation.
