Study Notes
Classifications of Vitamins
- Vitamins are classified into two major categories: water soluble and fat soluble.
Water Soluble Vitamins
- Comprised of B complex vitamins, folate, and vitamin C.
- Easily excreted through urine, leading to potential loss in the body.
Fat Soluble Vitamins
- Includes vitamins A, D, E, and K.
- Stored in liver and fatty tissues, allowing for accumulative storage.
- Do not contain nitrogen and are not routinely lost in urine.
- Some can be synthesized by the body, such as vitamin D.
- Support essential functions like cellular physiology, free radical scavenging, clotting, and gene expression.
Types of Water Soluble Vitamins
- Divided into two categories: non-B complex and B complex vitamins.
Non-B Complex Vitamin
- Ascorbic acid, also known as vitamin C, is the primary non-B complex vitamin.
Categories of B Complex Vitamins
- Three main categories: energy releasing, hematopoietic (blood development), and other.
Energy Releasing B Complex Vitamins
- Key vitamins include B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), Biotin, and Pantothenic Acid.
Individual B Vitamins
- Thiamine: Represents vitamin B1, crucial for energy metabolism.
- Riboflavin: Known as vitamin B2, involved in energy production and cellular function.
- Niacin: Identified as vitamin B3, plays a role in DNA repair and energy production.
- Biotin: A B complex vitamin that aids in energy metabolism.
- Pantothenic Acid: Another B complex vitamin essential for energy releasing processes.
Hematopoietic B Vitamins
- Folic Acid: Vital for blood cell development; deficiency can cause megaloblastic anemia.
- Vitamin B12 (Cyanocobalamin): Important for blood development and neurological function.
Other B Vitamins
- Pyridoxine: Also known as vitamin B6, plays multiple roles in metabolism.
- Pyridoxal and Pyridoxamine: Other forms of vitamin B6, contributing to various physiological functions.
Recap of Fat Soluble Vitamins
- Includes vitamins A, D, E, and K, collectively often referred to as ADEK.
Individual Fat Soluble Vitamins
- Vitamin A: Exists in forms such as retinol and beta-carotenes, important for vision and immune function.
- Vitamin D: Known as cholecalciferol, essential for calcium absorption and bone health.
- Vitamin K: Comprises phylloquinones and menaquinones, necessary for blood clotting.
- Vitamin E: Contains tocopherols, acts as an antioxidant protecting cells from damage.
