From Quiz Learning the ABCs
Answer:
B3
Vitamin B3 is the generic name for Niacin or Nicotinic Acid and Nicotinamide or the coenzyme forms of this vitamin. B3 vitamin is water soluble and thus not stored in the human body. It is found in many foods like yeast, meat (beef, chicken), liver, heart, kidney, fish, milk, eggs, peanuts and nuts, green vegetables, beans and cereals. It is also synthesized from tryptophan, an essential amino acid found in most forms of proteins.
Niacin is important in the metabolism of carbohydrates, fats and proteins. B complex vitamins are needed for healthy skin, hair, eyes, and liver and proper nervous system functioning. Mild deficiency can cause indigestion, fatigue, vomiting, depression, canker sores (aphtous ulcers).
Severe Niacin deficiency is a rare condition in developed countries, being usually caused by malnutrition and chronic alcoholism. It can occur in areas where people eat maize as a staple food. Severe and chronic deficit causes pellagra, a disease classically described by three signs: diarrhea, dermatitis and dementia (and eventually death if left untreated).
It's elemental! Words relating to space have become lost in Word Search boxes, each of which contains the answer to the written clues. For example: 'The Final Frontier' could be 'S Pa Ce'. Each answer contains 3 or 4 chemical symbols, in a straight line.
