Q

Vitamin D found in

Study These Flashcards
A

Liver
Egg yolk
Salt water
Fish

20
Q

Niacin uptake

Study These Flashcards
A

Absorbed in small intestine
Goes to tissues

21
Q

B5 importance

Study These Flashcards
A

No deficiency
Forms CoA
Important in tons of reactions

22
Q

B6 uptake

Study These Flashcards
A
  1. Digested in small intestine
    Pyridoxal 5 phosphate (PLP) turns to pyridoxal so it can be absorbed
  2. Absorbed and phosphorylated back to PLP
  3. Dephosphorylated to pyridoxal
  4. Oxidized to pyridoxic acid
23
Q

Folate uptake

Study These Flashcards
A
  1. Hydrolyzed to monoglutamate form in the intestine
  2. Reduced to dihydrofolate
    Using NADPH
  3. Reduced further to tetrahydrofolate
    in intestinal mucosa using NADPH
  4. Conjugated into polyglutamate form in tissues
24
Q

B12 uptake

Study These Flashcards
A

Absorbed in ileum
Need an intrinsic factor from parietal cells in stomach to absorb

In the blood
it forms B12 transcobalamin II complex
uptake by receptor-mediated endocytosis

25
Vitamin c uptake
Blood/tissue levels proportional to intake
26
Vitamin A uptake
By liver
27
Vitamin A storage
Stored as retinal ester
28
Vitamin D uptake
Light D3 Liver Hydroxylated in liver 1st Hydroxylated in kidney Calcitriol = active from Goes to Bone Kidney Intestine
29
Vitamin E uptake
Scavengers of free-radicals
30
Vitamin K uptake
Prothrombin made in liver Carboxylated prothrombin secreted in blood
31
Cofactor of thiamin and function
TPP Form and break C-C bonds oxidative decarboxylation transketolase in PPP turns glucose to ribose for DNA synth
32
Cofactor of riboflavin and function
FMN (flavin mononucleotide) or FAD (flavin adenine dinucleotide) They can accept 2 H to form FMNH2 or FADH2 Then FMNH2 and FADH2 can donate 2 H to form FMN or FAD REDOX
33
Niacin cofactor and function
Coenzymes in the NAD and NADP forms These dudes are hydrogen acceptors They combine with hydrogen as they are removed from food by dehydorgenases
34
B5 cofactor and function
CoA 2 main functions 1: conversion of decarboxylated pyruvic acid to acetyl CoA before CAC 2:degrades fatty acid molecules into lots of acetyl CoA
35
Coenzyme of B6 and function
Pyridoxal 5’ phosphate (PLP) AA metabolism It’s the coenzyme in the transamination for AA Also decarboxylation of stuff
36
Biotin is the prosthetic group of ____
Carboxylases Pyruvate carboxylase Acetyl CoA carboxylase Propionyl CoA carboxylase
37
Folate cofactor and function
THF Needs B6 and B12 It is a carrier of hydroxymethyl Forms purines: guanine and adenosine and thyamine
38
Cofactor and function of B12
Methionine It’s coupled with B6 and folate(THF reaction) Malonyl coa mutase is B5
39
Vitamin C key points
From D-glucose Good reducing agent Hydroxylated of collagen and carnitine Catecholamine synthesis
40
Describe the cathecholamine synthesis
Tyrosine —> Norepinephrine epinephrine dopamine dopa Need vit C as cofactor helping process along
41
Vitamin C and E
E = stationary cell membranes scavenger of free radicals C = mobile regenerate the reduced vit E
42
Basics of C and E antioxidant
E in the membrane Binds a free radical Transfers to C Uses thiol and GSH to get rid of it by oxidizing to create disulfide bond this has NADPH to NADP and H
43
Where can folate be trapped
N5 methyl THF
44
B6 PLP is used in
Transamination And Decarboxylation
