Max 3 for woman | 4 for men
50
Who should avoid alcohol?
Avoid if pregnant, operating machinery, can't control intake
51
What does alcohol has to be consumed with?
With food
52
Why you should eat CHO and fat before drinking?
CHO- slows absorption | Fat-reduces peristalsis
53
Is alcohol stored and what is the consequence for that?
Cannot be stored and that is why alcohol is the priority over anything else in the body
54
What does the conversion of alcohol to acetyl CoA require?
The B vitamins in its role as the coenzyme NAD.
55
What is NAD+?
NAD+ = niacin
56
Where is ethanol absorbed from?
If we don't eat, will absorb fast from the stomach Absorbed quickly from the stomach and duodenum
57
What is ADH? Where is it found?
Alcohol dehydrogenase and acetaldehyde dehydrogenase - Located in liver and in the stomach (ONLY IN MEN)
58
What is microsomal ethanol oxidizing system found?
Mitochondria of liver
59
What is inducible? What is non inducible?
- Microsomal Ethanol Oxidizing System is inducible - ADH is non inducible
60
Acetyl CoA molecules are blocked from getting into the TCA cycle by high levels of what? What does that cause?
- By NADH - Become building blocks for fatty acids - increased serum TG, increased risk of fatty liver - cirrhosis, ketones,
61
How does alcohol disturb metabolism?
- Less NAD+ - More H+ (generating acid) - Acetyl CoA produced produces fatty acids and ketones rather than entering TCA cycle - Decreased gluconeogenesis - Decreased protein synthesis - Liver damage
62
How does less NAD+ compromise metabolism?
pyruvate produces lactate rather than acetyl CoA Slows down glycolysis and TCA cycle
63
How does more H+ compromise metabolism?
acidosis along with lactate and increased ketone bodies
64
How does decreased gluconeogenesis compromise metabolism?
Ketosis
65
When do people experience hangovers?
When accumulating acetaldehyde
66
What happens to drugs when consumed with alcohol
Drug tolerance is created, because it stays more in the body
67
70 % of the ethanol is metabolized by____, and 20% of the ethanol is metabolized with ____
70 %- by Alcohol dehydrogenase | 20% by Microsomal Ethanol Oxidizing System
68
How is ethanol metabolized with ADH?
Ethanol->( with ADH in liver and stomach(men)) to acetaldehyde by NAD+ to NADH and H+->( with acetaldehyde hydrogenase only in the liver) to Acetate via NAD+ to NADH and H+ reaction-> CoA is added->FA->Liver
69
What happens with ethanol metabolism with MEOS? What is the other application of this circuit
Ethanol->( with MEOS in the mitochondria liver) NADPH and H+ and 1/2O2 to NADP+H2O->Acetaldehyde The same circuit to utilize the drugs
70
What is the rate of metabolism of alcohol
1 drink/hour
71
Where is the rest 10% of ethanol go?
Excreted through urine and breath
72
Why people black out when drinking?
Increased acidity in the blood-> cannot make glucose->black out
73
Where does acetylaldehyde go?
to Acetyl coa OR It can decline protein synthesize and cause cell damage->fibrosis->cirrhosis
74
What is fibrosis?
When the tissues in the liver start to collagenize
75
What inducible means?
Inducible- the rate of metabolizing the alcohol can change | Non-inducible- cannot be changedd
76
What happens with glucose part of metabolism with prolonged alcohol consumption?
-In liver increased glycolysis, decreased glycoenogenesis( from fat, AA)->low blood sugar->coma
77
What happens with pyruvate part of metabolism with prolonged alcohol consumption?
Increased pyruvate conversion to lactate->lactic acidosis->damage of the liver
78
What happens with fat part of metabolism with prolonged alcohol consumption?
Decreased fat breakdown,Increased fat synthesize->fatty liver
79
How you get fatty liver?
Acetyl CoA->Fat synthesis or ketones->Fatty liver->cirrhosis
80
What is cirrhosis? What is it caused by?
IRREVERSIBLE liver damage caused by alcohol, hepatitis B or C, iron toxicity (hemachromatosis)
81
What is the fatty accumulation called in cirrhosis? Inflammation?
Fatty accumulation: steatosis Inflammation: hepatitis
82
How does cirrhosis develop? What can it lead to? How do you treat?
- As liver constantly repairs, accumulation of fibrosis tissue, scars and nodules and connective tissue – impaired function - Leads to carcinoma --> liver resection, transplant
83
Can brain cells cure form alcohol damage ?
No
84
What does alcohol do to the brain?
- Sendates inhibitory nerves( central nerval system depressant ) - Less muscle control, less balance
85
Why do you want to pee more when drinking?
-Depression of antidiuretic hormone ->Loss of water and loss of important minerals
86

Wernicke-Korsakoff Syndrome – thiamin destruction Anemia – folate excretion Decreased vitamin D activation in liver B6 loss from binding protein
87
1 oz of EtOH=
0.5g fat
88
What happens to food consumption as alcohol consumption increases?
Less eating -> not eating a variety of other nutrients AND hard to break down alcohol
89
What does the French Paradox study state?
France: low CVD despite high saturated fat intake France was the only country that did not have a high death rate from CVD despite high saturated fat intake
90
What causes the French Paradox?
Very unclear, points to an association - Alcohol or flavinoids or combination - Resveratrol protects against LDL oxidation
91
What does consuming alcohol in moderation increase the risk of?

drink non-alcoholic beverages drink in moderation drink slowly drink with food don’t drive seek help if needed
93
