    Study Notes

    Overview of Water Soluble Vitamins: B and C

    • Water soluble vitamins are organic substances containing nitrogen that are easily absorbed in the jejunum and excreted in urine. The body does not store these vitamins and requires daily intake.
    • Vitamins B and C act as coenzymes and are required for carbohydrate, fat, and protein metabolism, as well as blood formation (hemopoiesis).
    • These vitamins can be destroyed by heat or air exposure and are lost in water used for cooking.
    • Vitamin C, also known as ascorbic acid, is important for the production of collagen, wound healing, improved immunity, antioxidant effects, and the protection of oral soft tissues.
    • Vitamin C is found in citrus fruits, green peppers, broccoli, tomatoes, and melons.
    • Vitamin C deficiency can lead to scurvy, which causes symptoms such as diarrhea, fatigue, depression, and impaired bone growth. It also affects the mouth, causing swollen and bleeding gums, delayed wound healing, sore and burning mouth, and malformed enamel and dentin.
    • Vitamin B1, also known as thiamine, provides energy to the brain, central nervous system, and heart. It is also a coenzyme in carbohydrate metabolism and niacin synthesis.
    • Vitamin B1 is found in pork, enriched grains and cereals, legumes, and nuts.
    • Vitamin B1 deficiency can cause conditions like beriberi, which damages the central nervous system and cardiovascular system, and Wernicke-Korsakoff syndrome, associated with alcoholism and characterized by mental confusion, eye movement abnormalities, and gait disorders.
    • Vitamin B2, also known as riboflavin, is important for growth, red blood cell production, and maintaining healthy eyes, skin, and mucous membranes. It is also a coenzyme for metabolism.
    • Vitamin B2 is found in organ meats, lean meats, fortified grains and cereals, eggs, cottage cheese, and milk.
    • Vitamin B2 deficiency can lead to a condition called ariboflavinosis, which manifests as angular cheilitis, glossitis, dermatitis, and anemia.
