Draw and name the enantiomer of D-glucose?
An enantiomer is a pair of structures which are mirror images of each other. For D-glucose:CHO | CHO| | |H--OH | OH--H| | |OH--H | H--OH| | |H--OH | OH--H| | |H--OH | OH--H| | |CH2OH | CH2OHOn the left is D-glucose, and on the right is L-glucose, mirror images.
What is the symbol OH is called?
it is called the hyrdoxyl unit. Hydro for the hydrogen, oxyl for the oxygen.
Does removing the -H and -OH ends now allow the molecules to fit together easily?
In a condensation reaction two molecules are covalently bound and water (H2O) is generated. As a rule, one molecule releases an -OH and one gives up a -H in the reaction.
What happends to the OH- as the H plus increases?
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
What are solutions that have more OH- then H ions called?
A basic solution has greater concentrations of OH- than H+ ions. The opposite is acidic. An easy mnemonic device for this is that you want to get an A+ not a B-.
What is process called when you dissolve Hydrochloric acid in water and what would be a balanced equation for this reaction?
It is called dissolving the acid. balanced equation: HCl+H(OH)-> H+Cl+H(OH)
What is a chemical reaction used by cells to make proteins nucleic acids and polysaccharides in which smaller molecules are joined together by removing an H and an OH to make a water molecule?
This reaction is a dehydration synthesis.

What symbol represents the ions in a glass of water?
OH- and H+ , and let's not forget H3O^+
What happends to the OH- as the H plus increases?
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
Water as H and OH- ions is essential in biochemical reactions such as what and what reactions?
H+ is a positively charged ion also called a proton and OH- is negatively charged, also called hydroxide. These can make up acid and base reactions.
What are solutions that have more OH- then H ions called?
A basic solution has greater concentrations of OH- than H+ ions. The opposite is acidic. An easy mnemonic device for this is that you want to get an A+ not a B-.
Which molecule represents an ion found in a glass of water?
OH- and H+
What do Japanese called their country?
Nihon (pronounced: Nee-h-oh-n)
Where does the extra electron in OH come from?
When a bond in water molecule H20 breaks it forms H+ and OH-. The extra electron comes from H. H-O-H ------> H+ + OH-
