Lecture 10 Flashcards
since fat + blood don’t mix,
the solution is lipoprotein
chylomicrons
carry dietary fat to liver & rest of body for burning or storage
VLFL turns into
LDL in bloodstream
HDL transports
fats to and from liver
VLDL & LDL
(lousy protein)
transport lipids to cells around body
HDL
(healthy)
removing lipids from cells body so they can be excreted
why we need lipids
- cell structure
- regulation of body processes
- ATP production
cell structure and lipids
lipids make cell membranes
- phospholipids keep them fluid
lipids and regulation of body processes
- vit absorption (a d e k)
- making hormones (sex h)
- blood pressure regulation
- building block to make other fats
- regulating blood clotting
atp production and lipids
high fat foods have high energy content (cells burn fat at rest and during excersize)
-FA transport in mito, where beta oxidation splits carbon chains into 2 carbon units that include acetyl COA and produce high energy e’s
ketone bodies are produced in ATP cycle if
if carbs are insufficient ketone bodies are produced
ketone bodies come from
fats (used as fuel in absence of carbs)
3 types of ketone bodies:
acetoacetate, B-Hydroxyl butyrate, acetone
lipids provide
insulation, protect organs, and important for making + protecting nervous system
lipids are needed for
energy storage
