cholestoral structure
few polar groups. saturated fat
1 of 16
what does saturated structure lead to
stacking. can from crystals in urine and blood, blocking blood vessles
2 of 16
synthesis of cholestoral
in liver. aceic acid-acetyl co a- melavonic acid-cholestarol. uses series of enzymes
3 of 16
statins mechanism
inhibitor. prevents pathway to melavonic acid. lowers ldl
4 of 16
fatty acids structure
carboxillic acids. can be saturated or unsaturated
5 of 16
saturated fatty acids features
no double bonds. straight chains. stacking. block blood vessles. unhealthy
6 of 16
unsaturated fatty acids features
double bonds curves and twists. cis - same sides- doesn't stack. trans-diff sides-stacks-unhealthy
7 of 16
triglyceride structure
3 fatty acid and glycerol-(CH2OH)2CHOH
8 of 16
hydrogenation process
addition of hydrogen molecule over double bond. can convert cis unsat to sat or trans unsat
9 of 16
lipoprotien structure
core- cholestroal and triglyerides. outer- free cholestoral, phospholipids and apolioprotiens
10 of 16
what is apolioprotien
protiens that bind lipids
11 of 16
types of lipoprotiens
chylomicrons,vldl,ldl,idl,hdl
12 of 16
what is chylomicron function
carries fat around body
13 of 16
which lipoprotiens are bad for you?
ldl/vldl. low in protien but high in fat. sticks to blood vessle walls and damage/blocks them
14 of 16
process of fat absorbtion
1.bile salts(produced in liver, stored in pancreas) dissolve fat to micelles 2. micelles absorbd in epitheal wall of intestines 3.enetrs golgi body,makes lipoprotiens- especially chylomicrons 4. chylo passed to lymph system, metabolised into other lipopro
15 of 16
pain and lipids
enzymes eg cox and PLA2 involved in syntheis of pain molecules such as archidonic acid which is a fatty acid
