Lipid and Protein Metabolism
Terms in this set (29)
The making of triglycerides is called _______________________. (Attachment of a fatty acid to a glycerol)
The breakdown of triglycerides is called _______________________. (Removing the Fatty acids from the glycerol)
cannot be attached.
Once the fatty acids are removed from the glycerol backbone - new fatty acids ______________________
In order for reesterification to occur the ________________________ needs to be converted to α-Glycerolphosphate
__________________________________ is produced by glycolysis (CHO) in muscle, heart, adipose tissue and is needed to reesterify glycerol to FA to form TGs.
Muscle, heart, adipose tissue cannot synthesize TG because they lack the _____________________ that phosphorylates glycerol to α-Glycerolphosphate.
is thought to occur primarily in the Liver (glyceroneogenesis).
_____________________ constitute the greatest part of lipid mass consumed in the diet.
Digestion of fat occurs in small intestine into an emulsified liquid via ______________________.
________________________________ hydrolyze the fats into monoglycerides, FFA, and glycerol.
__________________________ come into contact with epithelial cells in the small intestine and the lipids diffuse across the cell membrane.
_______________________ help transport fat in the blood (because fat is not water soluble) and are classified by their density.
The 3 Lipoproteins
LDL, VLDL, HDL
Lipoprotein Lipase (LPL)
_________________________ is responsible for "cleaving" Triglycerides (TG's) into FFA's and glycerol
________________________________ are responsible for the initiation of lipolysis
Carnitine Acyl Transferase (CAT)
Shown to be rate limiting step for fat oxidation (CAT I)
Degrades the fatty acyl-CoA to acetyl-CoA by cleaving the carbon atoms two at a time between the α and β carbons.
# of Carbons in fatty acid /2
Formula to find Acetyl-CoA from b-oxidation
(# of Carbons in fatty acid /2)-1
Formula to find how many b-oxidation cycles will be completed
is the rate limiting step of b-oxidation
Each cycle of β-oxidation produces ___ acetyl-CoA, FADH, and NADH.
The Randle cycle
_________________________ describes the regulation or interaction between FAT and CHO oxidation. Good evidence suggests this cycle occurs at rest in skeletal muscle (rat) but not during exercise. Glycolysis is shutdown to use fat as fuel.
Total amount of ATP from 1 acetyl-CoA
In order for AA to be used as fuel, the nitrogen containing ______________________ (groups) must be removed.
expensive and inefficient
Using AA for energy is _________________(cost of protein) ____________________ (extra metabolism involved).
_______________________ is removed from AA by two mechanisms: 1) Oxidative deamination and 2) transamination.
Small quantities of nitrogen are excreted as ammonia, however most nitrogen is excreted as ____________________.
Complements the Cori Cycle and Glucose-Alanine cycles by providing carbon and nitrogen from muscle to the kidneys for nitrogen excretion and gluconeogenesis.
Glucose Alanine Cycle
Complements the Cori Cycle and Lactate shuttle.
Leucine (BCAAs) combined with glycolysis make Alanine which can be converted to glucose by the liver
