Vitamins As Coenzymes Different Forms And Deficiency Disorders Ppt Vitamins, coenzymes, and cofactors are organic or inorganic molecules that promote or catalyze biochemical reactions and metabolism. they can work with or be part of enzymes. most cannot be synthesized by the human body and must come from dietary sources. they are involved in processes like carbohydrate, fat, and protein metabolism, cellular. Vitamin deficiencies can cause several disorders. there are 13 known vitamins classified as either fat soluble or water soluble. vitamin a deficiency can lead to night blindness and immune problems, while vitamin d deficiency results in rickets in children and osteomalacia in adults. both vitamins are important for growth, immunity, and calcium.
Vitamins As Coenzymes Different Forms And Deficiency Disorders Ppt Folic acid. folic acid deficiency is a relatively common vitamin deficiency in the united states, presenting routinely as macrocytic anemia. tetrahydrofolate (thf), the reduced coenzyme form of folate, receives one carbon fragments from amino acid donors such as serine, glycine, and histidine, and transfers them to intermediates in the synthesis of amino acids, purines, and thymidine. Water soluble vitamins common features: 1.water soluble 2.easy to be discharged through urine. rarely accumulated to the toxic concentrations. 3.their storage is limit. must be provided regularly. vitamin b12 is the only water soluble vitamin that can be stored in the liver for many years. There are three main types of nutritional anemia: iron deficiency anemia, vitamin b12 deficiency anemia, and folic acid deficiency anemia. iron deficiency anemia is caused by a lack of iron in the diet or an inability to absorb iron and can result in fatigue, pale skin, and shortness of breath. vitamin b12 deficiency anemia occurs when the body. Fig 7.32 (a) structure of vitamin k (b) vit k dependent carboxylation chapter 7. warfarin is an anticoagulant chapter 7. chapter 7 coenzymes and vitamins. some enzymes require cofactors for activity (1) essential ions (mostly metal ions) (2) coenzymes (organic compounds) . apoenzyme cofactor holoenzyme (protein only) (active) (inactive) .

B vitamins act as coenzymes in several enzymatic processes that support every aspect of cellular physiological functioning, including major functions within the brain and nervous system. any b vitamin deficiency can negatively affect mitochondrial metabolism of amino acids, glucose, and fatty acids through the citric acid cycle and electron. Presentation transcript. fat soluble vitamins • absorbed with dietary fat in small intestine • 40 90% absorption efficiency • absorption typically regulated by need • need absorption • transported away from small intestine in chylomicra via blood and lymph (depending on size) • they are not easily excreted through urine.
