Study Notes
Vitamin Classification
- Fat-soluble vitamins differ from water-soluble vitamins in that they can accumulate in the body and cause toxicity due to their ability to dissolve in fats and oils.
Fat-Soluble Vitamins
- Fat-soluble vitamins include vitamins A, D, E, and K.
- They are absorbed with the help of bile salts and fats in the small intestine.
- These vitamins are transported in the body by binding to lipoproteins or chylomicrons.
- The main function of fat-soluble vitamins is to facilitate various physiological processes, such as cell growth, bone development, and antioxidant activities.
Fat-Soluble Vitamin Absorption
- Fat-soluble vitamins require bile salts and dietary fats for absorption in the small intestine.
- Malabsorption of fat can lead to deficiencies in fat-soluble vitamins.
Fat-Soluble Vitamin Excretion
- Fat-soluble vitamins are not excreted in urine like water-soluble vitamins, but rather stored in adipose tissue and liver.
- Excess fat-soluble vitamins can be stored for long periods, which increases the risk of toxicity.
