Study Notes
Vitamin C: Sources, Metabolic Processes, Absorption, and Deficiency
- Vitamin C, also known as ascorbic acid, is an essential water-soluble vitamin required for several processes in the body.
- Vitamin C acts as a reducing agent in collagen synthesis, a cofactor for enzymes in the carnitine biosynthesis pathway, and a cofactor for enzymes in the catecholamine synthesis pathway.
- Citrus fruits, tomatoes, strawberries, potatoes, Brussels sprouts, and broccoli are good sources of vitamin C.
- A deficiency in vitamin C causes scurvy.
- Vitamin C is required in collagen synthesis, catecholamine synthesis, and carnitine biosynthesis.
- Vitamin C is actively absorbed in the small intestine and excess is degraded in the intestines.
- Hydro ascorbic acid is also an active form of vitamin C.
- Blood levels of ascorbic acid generally need to be above 80 milligrams per day for excess vitamin C to be excreted in the urine.
- A vitamin C deficiency can cause symptoms such as fatigue, weakness, and muscle and joint pain.
- A severe vitamin C deficiency can result in scurvy, which causes bleeding gums, skin rash, and joint pain.
- Vitamin C supplements can lead to excess vitamin C being excreted in the urine.
- It is important to consume a certain amount of vitamin C from dietary sources to avoid a deficiency.
