acid pH

Quite a few popular garden shrubs, annuals and vegetables do best in the moderately acid pH range, around 6 to 6.5.

A basic pH is usually perfered over an acid pH for most plants.

All industrial processes are based on neutral or acid pH values because though alkali treatments speed up conversion, they also promote degradation processes.

The latter contains grapefruit extract which maintains an acid pH on the skin's surface and has a mildly astringent effect on open pores.

It is stored in lysosomes and functions when these fuse with endosomes, which are acidified while they function; therefore, it has an acid pH optimum.

Doxycycline-metal ion complexes are unstable at acid pH, therefore more doxycycline enters the duodenum for absorption compared with the earlier compounds.

At neutral or acid pH, casein is relatively insoluble in water, and is easily separated from other milk proteins, sugars and minerals.

The net effect is that more pyrazinoic acid accumulates inside the bacillus at acid pH than at neutral pH.

It decomposes at an acid pH to form formaldehyde and ammonia, and the formaldehyde is bactericidal; the mandelic acid adds to this effect.

At neutral or acid pH, the reaction is slow, but is catalyzed by the enzyme carbonic anhydrase, which effectively creates hydroxide ions at the active site.

Under acid pH conditions, the addition of iron salts to a wastewater solution activates hydrogen peroxide to generate free radicals, which can attack a variety of organic compounds.

Simplistically, acid pH stains (negative charge) are attracted to the base pH tissue(positive charge), so they are called basophilic stains.

The native waters of Corydoras panda are consequently mineral-deficient, with a neutral to slightly acid pH, and replication of such conditions in captivity are recommended for successful maintenance.

They are principally sorting organelles where many ligands dissociate from their receptors in the acid pH of the lumen, and from which many of the receptors recycle to the cell surface (via tubules).

While staining is beneficial for experiments aimed at high resolution structure determination, it is highly undesirable in certain protein sample preparations, because it could destabilize the protein sample due to its acid pH and relatively high heavy metal concentration.

Ammonium chloride is used as a systemic acidifying agent in treatment of severe metabolic alkalosis, in oral acid loading test to diagnose distal renal tubular acidosis, to maintain the urine at an acid pH in the treatment of some urinary-tract disorders.

He came up with the concept of food combining (also known as the Dr. Hay diet), the idea that certain foods require an acid pH environment in digestion, and other foods require an alkaline pH environment, and that both cannot take place at the same time, in the same environment.
