+​ Water molecules split into ions of ​Hydrogen (H​ ) and Hydroxide (OH)​.  What is the pH scale? A mesure of how many free H​ ions there are in a solution.  +​ What is neutral pH? 7.0 H​ =OH  The greater the H​  concentration the l​ ower  ​ the pH, the solution is more a ​ cidic​  (pH<7)  +​ The lower the H​  concentration the​ higher  ​ the pH, and the solution is more  ​ basic ​ (pH>7)  What pH value are most of the fluids in your body? Slightly basic, between 7.3 and 7.5.  +​ Acid: molecule that gives away hydrogen ions (H​  protons).   Hypoventilation: Breathing too shallow, CO​  levels increase, blood becomes acidic.  2​ Respiratory Acidosis: Blood too acidic can cause coma and death.  Acid test​: Nitric acid can dissolve many metals, except gold. Often used to determine the  realness of gold metals.  Hydrofluoric acid​: Can cause delayed deadly reaction. Absorbed in skin without burning and can  prevent nervous system from normal function.  +​ Bases: molecules that accept free hydrogen ions (H​ )  Ex. If your stomach is too acidic take a base like tums CaCO​ +2H​ ­> H​ O + CO​ +Ca ​ 3​ 2​ 2​ Hyperventilation: Breathing too rapidly, CO​  levels dr2​, blood turns basic.  Tetany: Low CO​  causes calcium problems. Muscles remain contracted, can cause death.  2​ Tetanus​: (Lockjaw) has same symptoms but is caused by bacteria.  How do acids and bases burn you: they break down the molecules in the cell membrane,  releasing energy and heat. Cells fall apart and liquify.  +​ Salts: Molecules that release ions other than H​  when dissolved in water.  Why is sea salt bigger than table salt? It has more salts in it (NaCl, KCl, MgCl, CaCl)  Why is carbon an important biological element? Carbon can form 4 chemical bonds to get 4  electrons to finish its outer shell.  Functional group​: Single atoms or molecules covalently bonded to the carbon atom.   What is an alcohol? A hydroxyl group (OH that is attached to saturated carbons)  Ethanol (drinking alcohol): CH​ CH​ OH 3​ 2​ What is an organic molecule? A molecule that contains carbon and at least one hydrogen atom  Carbohydrates:​ sugars ( or saccharides) are polar, hydrophilic, and most common  Simple sugars:​ also called Monosaccharides (one sugar molecule) Ex: Glucose C​ H​ O​   6​ 12​ 6 prefered fuel for the brain and red blood cells.    Short Chain sugars​: Also called disaccharides or oligosaccharides. Ex: sucrose (table sugar),  milk sugar = Glucose + Galactose  What percentage of humans cannot digest milk sugar (lactose) after infancy? About 65%  In what regions of the world did lactose tolerance first evolve? North central Europe and Eastern  Africa  Long chain sugars​: Also called complex carbohydrates.   Cellulose​: Makes plant walls indigestible  Starch:​ How plants store the glucose they create  Glycogen:​ How animals store glucose they eat  Chitin​: Exoskeletons of insects (arthropods)  How are they similar and different? All are glucose chains, but differ in how the chains are linked  together.    Lipids: Greasy and oily: nonpolar and hydrophobic  Animal fats are​ solid​ at room temperature. Plant fats are​ liquid ​ at room temperature.  Fatty acids​: Some Omega­3 and Omega­6 are required in the diet because the human body  cannot make them.  Saturated fatty acid:​ Carbons are all joined by single bonds and are saturated with hydrogen  atoms.  Unsaturated fatty acid:​ There are double bonds between some of the carbons.  Triglycerides​: Most common lipids in the body, richest source of energy.   Where do vegetables store triglycerides? Inside fat cells  Why do we store fat not sugar? Because fats have twice as much energy as sugars.  Phospholipids:​ A main component of plant and animal cell membranes.  Waxes:  ​ All repel water  Cholesterols:​ Can be molded into many important biological molecules.  How do we make vitamin D naturally? In our skin, sunlight (uvb rays) converts one kind of  cholesterol into vitamin D.   Nucleotides: ​Have one sugar, at least one phosphate group, and one nitrogen containing base.   Ex: ATP, DNA and RNA  Proteins: ​ Are made from amino acids  Amino acids​: 20 different kinds used as the building blocks of proteins  Ex: The enzyme ​lysozyme​ is found in tears, sweat, and saliva, and kills some bacteria.
