saturated

saturated

-solids @ room temp. -single bond between carbon atoms -originate from animal sources

unsaturated

-liquids @ room temp. -don't bind maximum # of hydrogens due to double bonding between carbon atoms -originate from plants

mono saturated

one bond

poly saturated

-double bond -triple bond

dressings, oils, nuts

examples of unsaturated fat:

butter, mayo, lard

examples of saturated fat:

phospholipids

-make cell membranes -hydrophilic head and tail -one tail is saturated, other tail unsaturated

energy storage/ insulation/ protection

what is the purpose of fat?

steroids/cholesterol

manufacture of vitamin D and sex hormones and make up part of the cell membrane

wax

-prevents water loss -water insoluble

cholesterol

-clogs arteries -builds plaque

sugar

a form of lipid not found in the body?

-fats -phospholipids -cholesteral/steriod -waxes

4 types of lipids:

it stains

How to tell if it is a lipid:

Lipid

-store energy -signalling -indissoluble in water -struct components of cell membrane

Neutral fats

-stores energy fuel -insulates body temperature -triglycerides -cushions/protects organs

Triglycerides

a type of lipid that gives the body energy

phospolipids

-chief component of all cell membranes -2 layers self assemble to form membrane -modified triglyceride

cholesteral

-builds/maintains membrane -composes over 30% of all animal cell membrane

It helps to stabilize all animal cell membranes; the body uses it to synthesize steroid hormones; used in vitamin D and bile synthesis

why is cholesterol important?
