what are fats and lipids made from
conatin carbon oxygen and hydrogen
1 of 10
how are they formed
they are formed from a condenstion recation between a glycreol and fattyu acid, for every 1 glycerol theres 3 fatty acids, the glycerol is lipid and the fatty acid component varies and an oxyhen bond is formed known as an ester
2 of 10
twp types of fats
saturadte with single bond and unsaturated with double bond. to much of unsaturated can give you heart disease
3 of 10
propeties of lipids
lipids are insoluable and fats are solid at room temp and oils are liqued at room temp
4 of 10
functions of lipids
protect internal organs sucha s kidneys and and ae inder the skins so are a thermal heat insulator
5 of 10
what is a phopholipd
is where one of the fatty acid gruops has been replaced by a phosphapte group
6 of 10
propeties of the lipid and fatty acid within a phospholipid
the lipid head is polar and attracted to eater hydrophilic and they aftty acid tail is non polar and reples water and is hydrophobic
7 of 10
what is the cell membrane made uo of
protein and phospholipids
8 of 10
why is it called a fluid moasic
the bilayer and all of the compinents are free to move
9 of 10
what does the membrane allow to pas through
small uncharged particles can pass through the membrane such as oxygen and crabon dioxide however large molecules such as ions cant pass through
