Exam - Pantothenic Acid Flashcards
where is pantothenic acid present
everywhere - virtually all plant and animal food
is there pantothenic acid deficiency
next to impossible
is there any toxicity associated with pantothenic acid
little to none
how does pantothenic acid occur in foods
in free and bound forms
what does most pantothenic acid in food occurs as
a part of coenzyme A
where is pantothenic acid absorbed
in jejunum by passive diffusion
how is pantothenic acid found in blood
free
how does pantothenic acid uptake occur
through the sodium dependent multivitamin transporter
what is pantothenic acid a precursor in
the synthesis of CoA
how is pantothenic acid a precursor for CoA
pantothenic acid –> 4-phosphopantetheine –> Coenzyme A
what is 4-phosphopantetheine the active form in
fatty acid synthesis - important component of acyl-carrier protein in the fatty acid synthase complex
what is CoA the active form in
oxidative reactions - energy production and formation of acetyl-CoA
what is required to make CoA
cysteine
