what is true about the energy storage capabilities of trigylcerides as compared to that of carbohydrates?
- burning trigylcerides produces about 9 kcal/g but burning carbohydrates produces about 4 kcal/g
what transports cholesterol to the liver? HDL
what statement about glycerophospholipids is incorrect? The fatty acid on carbon 1 of glycerol is always saturated
blood type O is the universal donor bc none of the other blood types has antibodies against type O
fasting blood glucose level of a healthy person is 70/100
what describes type 1 diabetes? Absolute insulin deficiency
what polysaccharides are all glycosidic linkages of the B(1-4) type? A) amylose B) glycogen C) amylopectin D) none of above
when glycogen is completely hydrolyzed, glucose will be produced
the relationship between D & L Frustose is enantiomers
Amylopectin’s glycosidic linkage is a(1-6)
Released by alpha cells of the pancreas – glucagon
Responsible for maintaining glucose level by signaling the liver to produce glucose in the fasting state – glucagon
Responsible for glucose disposal and uptake in the body – insulin
Responsible for the rate of glucose appearance in the body. Works as a signal to the brain to promote satiety – amylin
Released by fat cells that resists insulin – resistin
All physical properties of enantiomers are the same- f
all open-chain monosaccharides are chiral molecules – f
a-d-glucose and b-d-glucose rotate plane polarized light to the same direction – t
fats and oils are triglycerides - t
all monosaccharides are reducing sugars – t
Penultimate – Determines L or D
Anomeric – Head carbon
Cellobiose – glucose + glucose B(1-4)
Maltose – glucose + glucose a(1-4)
Lactose – galactose + glucose B(1-4)
Sucrose – glucose + fructose a,B(1-2)
Celluolose – BD glucose w/ many B(1-4) bonds CANT DIGEST
Starch – amylose – aD glucose a(1-4) links
Amylopectin – a(1-4) and (1-6)
Carbs- most abundant 2% humans, 75% plants
