pH = -lg [H+]\n\nHence, \npH = 3 means [H+] = 10^ -3\npH = 5 means [H+] = 10^ -5\n\npH = 3 has 100 times more H+ ions in the same volume of solution than that of a pH = 5, which means it is 100 times more acidic

Biochemistry focuses primarily on enzyme catalyzed and controlled chemical reactions.  Untimately, it is the study of all chemical processes endemic to life, but in practice this means that they focus primarily on the large proteins that serve to control and quicken biological chemical pathways.  They look at the way that chemical cascades are triggered or halted by looking that the interactions between proteins and the various substrates they work on.\n\nBroadly, we refer to biochemical pathways as metabolism.  This involves both catabolism (breaking down chemicals for energy, nutrients, or detoxification) and anabolism (the building of proteins to serve functions in the body--think "anabolic steroids," which make the body build excessive muscle protein.  "Anabolic" refers to the fact muscle growth is part of anabolism).

In general science terms, an acid is a molecule or ion that, when placed in water, will give up a hydrogen ion (H+) to a base, or accept an unshared pair of electrons from a base. \n\nA base is a substance which dissociates (separates) in aqueous solution to yield hydroxyl ions (OH-) which react with an acid to form a salt.\n\nAcids and bases react with one another in a neutralization reaction to form a salt. This is also the basis of buffers.\n\nIf you want to get down the simplest definitions: \n\nAn acid is a solution that has more free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH less than 7.\n\nA base is a solution that has less free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH of more than 7.

A nutrient is any element or compound necessary for or contributing to an organism's metabolism, growth, or other functioning. Six nutrient groups exist, classifiable as those that provide energy, and as those that otherwise support metabolic processes in the body: Some of them are essential because they cannot be synthesized in the body and must be obtained from a food source.

pH (potential hydrogen) is a measure of the activity of hydrogen ions (H+) in a solution and, therefore, its acidity or alkalinity. In aqueous systems, the hydrogen ion activity is dictated by the dissociation constant of water (Kw = 1.011 × 10−14 at 25 °C) and interactions with other ions in solution. Due to this dissociation constant a neutral solution (hydrogen ion activity equals hydroxide ion activity) has a pH of approximately 7. Aqueous solutions with pH values lower than 7 are considered acidic, while pH values higher than 7 are considered alkaline..\n\npH = -log(concentration of H+)\njust use the equation to figure it out.\nhttp://en.wikipedia.org/wiki/PH

as we know the PH of blood is 7.4 so the molar concentration of hydrogen ions within a healthy human's blood will be 10 to the power -7.4

well, i don't know  where to find a quiz, however i am a respiratory therapist and use these everyday\n\nhere are some ideas\nokay normal ph in your body is 7.35-7.45 <7.4 is acidic, and >7.4 is basic (alkalotic)\n\nthink of hco3 (bicarb) your buffer, it raises the ph\n\nthink of co2 acidic.. it lowers the ph\n\no2 levels are normal if they are >80 (remember copd pts will have 50's and that will be normal\n\nok... \nexample 7.30ph, 55 pco2, 80 po2, and 29 hco3\nthat is an acidic ph.. its acidic because the person isn't blowing off co2, the normal co2 is 35-45, its 55\n\nthe hco3 isn't raised up high enough to buffer the acidity.. so the blood gas is uncompensated, meaning the hco3 and co2 will usually compensate for one another.\n\nthis gas is an u ncompensated respiratory acidosis, with normal oxygenation\n\nnext gas 7.38ph, pco2 is 50, hco3 is 40, and po2 is 50\nthis is a normal ph, with elevated pco2, the ph is an acidic ph.. however in normal level, notice the hco3 is elevated.. it compensated for the raised co2\nalso notice the po2 this is normal for co2 retainers (copd patients). \n\nthis gas is a compensated respiratory acidosis with hypozemia (however normal for the copd patient)\n\nokay next gas\n7.50ph, with 35pco2, hco3 42 po2 is 70\nthis is an uncompensated metabolic alkalosis.. the  pco2 is normal.. not compensating..\n\nnext gas 7.20ph, 5 pco2, hco3 10\nthis is an partialy compensated metabolic acidosis.. meaning that the pco2 is trying to make up for the loss of bicarb.. this is a blood gas that you will find with a diabetic keto acidosis patient.\n\nnext gas 7.48ph, pco2 25 hco3 20\nthis is a gas that is uncpmpensatted respiratory alkalosis.. t his patient might have a respiratory ailment that is causing them to hyperventalate... blowing off too much co2\n\nthe hco3 will trend down to compensate\ni hope this helped

Biochemistry\n\nThe chemistry of biology, the application of the tools and concepts of chemistry to living systems. \n\nBiochemists study such things as the structures and physical properties of biological molecules, including proteins, carbohydrates, lipids, and nucleic acids; the mechanisms of enzyme action; the chemical regulation of metabolism; the chemistry of nutrition; the molecular basis of genetics (inheritance); the chemistry of vitamins; energy utilization in the cell; and the chemistry of the immune response.\n\nFields closely related to biochemistry include biophysics, cell biology, and molecular biology. Biophysics applies to biology the techniques of physics. Cell biology is concerned with the organization and functioning of the individual cell. Molecular biology, a term first used in 1950, It overlaps biochemistry and is principally concerned with the molecular level of organization. \n\nThe science of biochemistry has also been called physiological chemistry and biological chemistry

Looks like the body part was answered.\n\nIn industry, pH is important because it could be the deciding factor for a process to work or not.  In mass production of something, minute changes could determine the efficiency of a process, the type of product, the dimensions of the product, and/or the amount of money needed for proper manufacturing equipment.  If you are dealing with concentrated acids and bases, you will need vessels that would be able to withstand corrosion and fume hoods, with additional sensors and equipment, not to mention extra precautions to avert deaths. In industry, by changing the concentration of the pH of an ingrediant, you could alter the reactivity of the substance.  Additionally, you could change how a catalyst functions.  It is known that as with any metal, catalysts can degrade a lot quicker under certain conditions.\n\nJust as how the body needs to regulate pH in order to maintain optimal performance of their catalysts (proteins), industry must do the same.

What I think you're talking about are how acidic and how basic something is according to the pH scale.  Maybe?  \n\nWe us the pH scale to describe how acidic or how basic a solution is. pH stands for potential of hydrogen. It's numbered from 1 to 14--increasing in basicity.\n\nHydrogen and hydroxide ions are very reactive, and the proper balance of these ions is critical for the proper functioning of chemical processes within an organism.\n\nA compound that donates hydrogen ions to solutions is called an acid.  Examples of an acid would be something like lemon juice and tomato juice.  Even the gastric juice inside of your stomach.\n\nA base is a compound that accepts hydrogen ions and removes them from solutions.  Examples of a base would be something like bleach or oven cleaner.\n\nThe increasing acidity means there's a higher concentration of H+.  The decreasing basicity means there's a lower concentration of H+.  \n\nPURE WATER is neutral----or 7 on the pH scale.\n\nHope this helps. :o)

medicine, metabolic acidosis is a state in which the blood pH is low (under 7.35) due to increased production of H+ by the body or the inability of the body to form bicarbonate (HCO3-) in the kidney. Its causes are diverse, and its consequences can be serious, including coma and death. Together with respiratory acidosis, it is one of the two general types of acidosis.
