usually are small and lack carbon.
always contain carbon usually contain hydrogen and always have covalent bonds
is the most abundant substance in the body. It is an excellent solvent and suspending medium, participates in hydrolysis and dehydration synthesis reactions and serves as a lubricant. It also has a high capacity for absorbing heat and a high heat of vaporization
have many hydrogen bonds making it cohesive and causing it to have a high surface tension.
have a PH which must remain fairly constant to maintain homeostasis
is represented by 7 on the pH scale
are below 7 on the pH scale
are above 7 on the pH scale
Normal blood pH
7.35 - 7.45
remove or add H+ ions to help maintain pH homeostasis
Carbonic acid - bicarbonate
one of the important buffer sytems
Bicarbonate ion (HCO3)
enables carbon dioxide to be carried safely int he blood stream
