Water-Soluble Vitamins and Vitamin C

which vitamins are considered water soluble vitamins

Vitamin C and the B vitamins

water soluble vitamins

dissolve in water

water-soluble vitamins can be lost when they

leach into cooking water

which factors can destroy water soluble vitamins

heat, light, and oxygen

After absorption, water-soluble vitamins are transported primarily through:

Blood and extracellular fluid

water soluble vitamins are primarily excreted through the

urine

becuase excess water soluble vitamins are commonly excreted in urine, toxicity is generally

unlikely

which statement about water soluble vitamins is true

there is no major storage site for them

because water soluble vitamins have little storage in the body, a persom

can become deficient

according to the slides, a few water soluble vitamins can remail in tissues for

1 month

Vitamin C is also know as

Ascorbic acid

vitamin C deficiency causes

scurvy

historically, sailors were dying from

scurvy

which foods helped prevent sailors from dying of scurvy

orange and lemons

Vitamin C

Vitamin C assists enzymes involved in the formation and maintenance of

collagen

collagen is the base of

which structure depends on collagen and connective tissue

bones, teeth, skin, and tendons

vitamin C Helps provide supporting material for

capillaries

Carnitine is involved in

transporting fatty acids

vitamin C acts as an

antioxidant

as an antioxidant, vitamin C protects against

free radical oxidation

vitamin C protects iron from oxidation in the

intestines

vitamin C promotes the absorption of

iron

vitamin C also helps reduce

tissue inflammation

What happens to collagen during Vitamin C deficiency?

which group is at risk for vitamin C deficiency

Vitamin C can be lost when food is

cut

which food related factor can decrease vitamin C

long storage

processing food can

destroy vitamin C

Which statement BEST explains why water-soluble vitamins can become deficient?

They have no major storage site and can be lost/excreted.

Which sequence is correct for Vitamin C deficiency?

Low Vitamin C → collagen breakdown → scurvy

Which combination BEST describes Vitamin C?

Water-soluble + antioxidant + collagen formation + iron absorption

A person eats enough iron but has poor iron absorption. Which vitamin could help?

Vitamin C

A person frequently eats processed foods that have been stored for a long time. Which vitamin may be particularly affected?

vitamin c

Which statement is FALSE about water-soluble vitamins?

thay have a major storage site in body fat
