|
Glyconic Acid
|
Glucose reacts with oxygen O2 to make a carboxyl group
Glucoronic acid |
|
|
Glucose metabolism in the liver
|
Liver takes glucose and makes glucoronic acid
Glucoronic acid and biliribun bilirubin glucuronide discharged through the intestines and urine (urbill) Bilirubin comes from hemoglobin degradation - light sensitive |
|
|
Glycerides
|
Made up of glycerol and fatty acids through dehydration synthesis and an ester bond is formed
Glycerol is an alcohol |
|
|
Monoglyceride
|
Glycerol and one fatty acid chain
|
|
|
Fatty acids
|
pic
Long carbon chains with H atoms attached and a carboxylic acid (-COOH)group at one end Butyric acid - butter fat |
|
|
Lipids
|
Contain C:H in a 1:2 ratio like carbohydrates, but have much less oxygen
Ex: C12H24O2 |
|
|
Fats
|
Fats are esters
|
|
|
Diglyceride
|
glycerol and 2 fatty acid chains
|
|
|
Triglyceride
|
Glycerol and 3 fatty acid chains
|
|
|
Glycerides
|
Glycerol monobutyrate is a monglyceride; It i glycerol and one fatty acid chain (butyric acid) combined through dehydration synthesis
|
|
|
Stearic Acid
|
?butyric acid
C17H35-COOH # of H is 2 (17) + 1 = 35 |
|
|
Oleic Acid
|
Mixed triglyceride
|
|
|
Saturated Fatty acids
|
In a saturated fatty acid, each C in the tail has 4 single covalent bonds - 2 to H and 2 to C
The carbon at the end of the tail has 3 H atoms In an unsaturated fatty acid, one or more of the single covalent bonds between carbon atoms becomes a double bond, so each of those carbon atoms bins with only 1 H atom. A monounsaturated fatty acid has one double bond A polyunsaturated fatty acid has multiple double bonds |
|
|
Unsaturated Fatty Acids
How to figure out how many double bonds |
If have C19,
should have 2(19) +1 = 39 H C19H31-COOH Do 39-31 = 8; divide by 2 = 4 doyuble bonds |
|
|
Unsaturated Fatty Acids FOR TEST
How to figure out how many double bonds |
C17 H31 - COOH
If 17 carbons, should have 35 H atoms; 35-31=4; divide by 2 - 2 double bonds |
|
|
Characterize fatty acids
|
1 double bond - monounsaturated
2 double bonds - diunsaturated 3 or more double bonds - polyunsaturated |
|
|
Fats

Glycogen readily broken down |
