Document Summary

These chemical bonds allow the formation of chemical compounds which may be organic or inorganic: : organic substances - covalently bonded carbon (c) atoms. E. g. carbohydrates, proteins, lipids and nucleic acids : inorganic substances usually lack c atoms. With the exception of these inorganic compounds which contain c atoms: . (bicarbonate) : water (inorganic, acids and bases. 2 hydrogen (h) atoms and 1 oxgen (o) . Polar molecules unequal sharing of electrons leads to a slight charge difference . Many reactions in the body take place in h2o = universal solvent . May be organic or inorganic lomoar cpsd| 987298: acids: Dissociate in h2o releasing h+ ions : [h+] = ph, e. g. hydrochloric acid (hcl) in h2o h+ + cl, bases: Substances that bind free h+ ions in h2o : [h+] = ph, e. g. 1: naoh in h2o na+ + oh- (hydroxyl ion) then oh- (base) + h+ h2o e. g. 2: hco3, oh- and hco3.
