LIPIDS
made up of glycerol attached to 1-3 fatty acid chains
LIPIDS
body’s primary long term energy storage molecules
LIPIDS
used for hormones, structural elements of cell membranes and vitamins
LIPIDS
serve as cushion and insulator of our organs
LIPIDS
water-insoluble —> hydrophobic
LIPIDS
oils, waxes, phospholipids, steroids
CARBOHYDRATES
most abundant class of bioorganic molecules
CARBOHYDRATES
serve as energy sources and considered as essential constituents of all living things
CARBOHYDRATES
final products of various metabolic processes
sugars and starches
Examples of carbohydrates
NUCLEIC ACIDS
main information-carrying molecules of the cell and can determine the inherited characteristics of every living thing
Nucleotide
basic unit of nucleic acids
PROTEINS
primary building materials of the body
PROTEINS
contain the elements CHON and most also contain sulfur
PROTEINS
naturally occurring, unbranched polymer in which amino acids are the monomers
PROTEINS
usually involved in muscles
Lipids
make up the membranes of the cell
Lipids
energy-rich molecules mostly made up of hydrocarbons
fatty acids, glycerol, sphingosine, and sterol
primary building blocks of lipids
Fatty acids
monomer unit of Lipids
FATTY ACIDS
to its isolation from naturally occurring fats
9
each gram of fat releases __ kcal of energy
Adipocytes
most energy stored in the body is in the form of lipids; fat cells known as
phosphoglycerides, sphingolipids, and steroids
compose the basic structure of all cell membranes
steroid hormones
critical chemical messengers; allow tissues of the body to communicate with each other
dietary fat
carrier of lipid-soluble vitamins
Protein
serve as shock absorber or protective layer for the vital organs
Lipids/Fats
insulate the body from extremes of cold temperature
SATURATED FATTY ACIDS
only C-C single bonds
SATURATED FATTY ACIDS
linear, fully extended
UNSATURATED FATTY ACIDS
bend carbon chain at site of C-C double bond
Higher
Melting point of saturated fatty acids
