Lipids Flashcards
Lipid
contain a fatty acid or steroid nucleus
HDL
High density lipoprotein
LDL
Low density lipoprotein
types of lipids
waxes,fats,oils, tryglycerols and phospholipids
saturated
c-c no double bonds
unsaturated
c=c double bonds
waxes
esters of saturated fatty acid and long chain alcohols
tricylglycerols
3 fatty acids all connected to a 3 carbon alcohol
fat at RT
solid
Oil at RT
liquid
phospholipid
phosphate glycerol and amino alcohol
Cholesterol level
200mg/dl
steroid hormones
chemical messengers that serve as a communication system
bile salts
break fat in our body for us to ingest
Hydrogenation
double bonds in unsaturated fatty acids react with H to produce single bonds
Esterfication
3 fatty acids and glycerol react to produce fat and 3 H2O
Hydrolysis
fat and 3 H2O react to produce 3 fatty acids and glycerol
Soapification
fat + 3NAOH react through heat to produce soap and glycerol
Glycerophospholipids
two fatty acids form ester bonds
plasma membrane
separates internal cytoplasm from the external environment
membrane external
hydrophilic polar heads
membrane internal
hydrophobic fatty acid tails
glycoprotein
proteins attached carb chains
glycolipids
lipids attached to carb chains
