Scurvy is perhaps the oldest known deficiency disease. However‚ its specific relationship to ascorbic acid was not recognized until the 20th century. It generally occurs between six and 18 months of age‚ but can start much earlier in pre-mature babies or those borne of mothers who lacked nutritious food during their later stages of pregnancies. This makes it a type of malnutratian. Mal nutrtiian is a pretty broad typic but a lot of children suffer from it ‚ Malnutrition is a dietary condition caused

EXPERIMENT TO STUDY THE EFFECT OF A FACTOR AFFECTING VITAMIN C IN FRUIT JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit juices will then be recorded to see

Rick & Rosalinda Puetter—Personal vitamin/supplement use and practice‚ 6 February 2000. Vitamins‚ Supplements & Their Uses I. Introduction Our interest in vitamins‚ dietary supplements‚ and nutritional biochemistry began in 1994. I in particular was a severe skeptic about supplements in general‚ and thought everything one’s body needed could be supplied from a “healthy diet”. This‚ of course‚ is true to some degree. Healthy diets allow one to live a long and pleasant life. This does not mean

Vitamins Vitamin is defined as any of a group of organic substances essential in small quantities to normal metabolism‚ found in minute amounts in natural foodstuffs or sometimes produced synthetically (Dictionary.com‚ 2012). We need vitamins and minerals for our bodies to function properly. By eating a variety of foods‚ we can often supply our bodies with the necessary vitamins it needs‚ but in some cases it is necessary to take a vitamin supplement as well. By eating a good diet in conjunction

Vitamins Vitamins are vital organic nutrients essential to over all health and are needed for cells and fluids in the body. They are found in all the foods that we eat‚ and must be consumed in small quantities since our bodies cannot make them. They are also available in dietary supplements‚ but those are only suggested if necessary‚ like if the body is not getting enough vitamins from food. Even though vitamins do not supply energy as carbohydrates‚ fats and proteins do‚ they are vital because

Vitamin A Retinoic acid‚ or Vitamin A‚ is an essential human nutrient referring to a family of similarly shaped molecules called the retinoids. Its discovery dates back to research done in 1906‚ which indicated that factors other than carbohydrates‚ proteins‚ and fats were necessary to keep cattle healthy. Vitamin A was independently discovered by Elmer McCollum at the University of Wisconsin-Madison‚ and Lafayette Mendel and Thomas Osborne at Yale University. It was named due to the fact that

VITAMINS Introduction Vitamins are organic food substances found only in living things‚ i.e. plants and animals. They are essential for our bodies to function properly‚ for growth‚ energy and for our general well-being. With very few exceptions the human body cannot manufacture or synthesize vitamins. They must be supplied in our diet or in man-made dietary supplements. Some people believe that vitamins can replace food‚ but that is incorrect. In fact‚ vitamins cannot be assimilated without also

Vitamins In the early 20th century the discovery of vitamins began. Today there is a chance that there are some vitamins that are still undiscovered. The definition of vitamin is: one of several substances necessary for animal nutrition‚ and occurring in minute quantities in natural foods; numerous types have been distinguished‚ and designated by the letters of the alphabet. Each and every living animal needs vitamins to grow and be healthy. Since the human body can t produce

Spectrophotometric determination of Ascorbic acid Concentration in an Unknown Solution Introduction: The naturally occurring organic compound with antioxidant properties is Ascorbic acid shortly referred as (AA). Normally the color of Ascorbic acid is white‚ but in some cases of impure samples it appears yellow in color. Ascorbic acid is solid in state. In water it dissolves well to give mildly acidic solutions. Ascorbic acid is one form ("vitamer") of vitamin C [1]. So‚ Ascorbic Acid (AA) in other
