Biomolecules/Water Flashcards
Biomolecules
organic molecules which combine to form living organisms; includes carbohydrates, lipids, proteins and nucleic acids
Carbohydrates
Broken down to simple sugars, end in -ose
Lipids
Energy-rich organic compounds, such as fats, oils, and waxes, made of glycerol and fatty acids
Nucleic acids
Contain nucleotides
Proteins
Chains of amino acids
Carbohydrates are made of the elements
C, H, O
Lipids are made of the elements
C, H, O
Nucleic are made of the elements
C, H, O, N, P
Proteins are made of the elements
C, H, O, N
Catabolism
Breaks down, eg hydrolisis (Releases energy)
Anabolism
Forms molecules, eg dehydration (Requires energy)
Nonpolar
Electrons are shared equally, weak but important for biological structures
Polar
Unequal distribution, most large biological molecules
Water makes up what percentage of cells?
60-80%
Most abundant and important inorganic compound in living cells.
Water
