Description
Vitamin B3. Computer model of a molecule of the water-soluble vitamin B3 (niacinamide or nicotinamide, C6.H6.N2.O). The atoms (solid tubes) of this organic molecule are colour-coded: carbon (yellow), hydrogen (grey), oxygen (red) and nitrogen (blue). Sources of niacin include cheese, milk, meat, poultry, fish, eggs and whole grains. Required to maintain normal digestive function, it also helps to reduce cholesterol levels. A lack of niacinamide can lead to pellagra, with symptoms of depression and dermatitis. Small amounts of vitamins are an essential part of a healthy diet, providing enzyme cofactors for the varied biochemistry of body metabolism.
