1. Vitamins LECTUREArticle teachersM.sc. Zainab Mohsen F.I.C.M.S Path Dr. Ammar HatemAl-Mustaqbal University CollegeAnesthesia Techniques Department
2. Introduction of VitaminsOrganic molecules, essential for the normal growth and development, required in tiny amountsMost of them cannot be synthesized by mammalian cells, must be supplied in the diet
3. The Classification of Vitamins1- Water-soluble： (Vitamins B complex and C) thiamineVB1, riboflavinVB2, niacin （VB3）, pantothenic acid （VB5）, VB6, biotin（VB7）, folic acid（VB11 ?VB9 ）, cobalaminVB12, VC Water-Soluble Vitamins are Soluble in water (Vitamins B and C) Used as helpers by many enzymes ( coenzymes ).Not stored in the body -get extra are urinated out
4. 2- Fat-Soluble Vitamins A, D, E, and K.Soluble in lipids, but not in water.Important in vision, bone formation,antioxidants, and blood clotting.Stored in the body.
5. Water soluble vitamins (B complex and vit C)Thiamin (Vitamin B1)Active form : Thiamin pyrophosphate（TPP）The first discovery of vitaminDeficiency results in beriberi (fatigue, weightloss, and nerve degeneration).
6. Deficiency VB1：beriberi
7. Riboflavin (Vitamin B2) is Needed for good vision and healthy skin.Niacin (Vitamin B3)Deficiency can results in a condition known as pellagra. Pellagra includes the triad of 3D :dermatitis, dementia, and diarrhea.Is found in meats, rice, and whole grainsPantothenic Acid (Vitamin B5) needed for energy production as well as making glucose and cholesterol.Deficiency can result in fatigue, retarded growth, cramps, and anemia.Is found in salmon, meat, eggs, whole grains, and vegetables.
8. Pyridoxine (Vitamin B6)Deficiency - Anemia - Skin problems - Sores in the mouthCobalamin (Vitamin B12)Is a coenzyme for enzymes that transfer methylgroups and produce red blood cells.Deficiency can lead to megaloblastic anemia and nerve damage
9. Ascorbic Acid (Vitamin C) Is required to make collagenDeficiency can lead to weakened connectivetissue, slow-healing wounds, anemia and scurvy.Is found in blueberries, citrus fruits, tomatoes,broccoli, red and green vegetables.
10. Fat soluble vitamins ( A, D, E, K )Vitamin Ais obtained from meats and beta-carotenes in plants (carrots for example)Beta-carotenes are converted by liver enzymes to vitamin A (retinol) which is mportant in vision, bone growth, and healthy skinVitamin EIs an antioxidant in cells.Is found in vegetable oils, whole grains, and vegetables.
11. Vitamin K is needed for activation of blood clotting factors so its deficiency associated with bleeding .Vitamin D (D3)Is synthesized in skin exposed to sunlight.Regulates the absorption of phosphorus andcalcium during bone growth.Deficiency can result in weakened bones.Sources include egg yolk, and milk.
12. Deficiency of vit D: rickets in children osteomalacia in adults
13. GOOD LUCK
