they are bound to albumin
they are sent to tissues for beta-oxidation
red blood cells, because they lack mitochondria
the brain because FFAs cannot cross blood brain barrier
Fatty acid + CoA + ATP <-->
acyl-CoA + AMP + PPi
carboxylate group attacks the phosphate closest to adenosine on ATP, breaking off two phosphates.
This yields acyladenylate mixed anhydride. (thioester bond)
CoASH is added and creates acyl-CoA and AMP
maintains malonyl-CoA pools
fatty acyl CoA
--[acyl-CoA dehydrogenase (AD)]-->
fatty acyl-CoA and acetyl-CoA
palmitoyl CoA + 7CoA + 7FAD + 7NAD + 7H2O
8 acetyl-CoA + 7FADH2 + 7NADH + 7H+
what are the two problems cause by unsaturated fatty acids
1) the creation of a double bond btwn C3 and C4 (instead of C2-C3 needed for enoyl CoA hydratase)
2) (for linoleic acid beta oxidation) 2,4-dienoyl is created, which has a C4-C5 double bond and a C2-C3 double bond.
lipase is activated
stimulates the lipolysis of storage fat.
"StudyBlue is great for studying. I love the study guides, flashcards and quizzes. So extremely helpful for all of my classes!"Alice , Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"Tim , University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly!??I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"Jennifer , Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"Justin , LSU
