PLM of niacinamide crystals
Numéro d’image : 11521239
| Polarised light micrograph of crystals of niacinamide (also known as nicotinamide). This is the amide of nicotinic acid,the two compounds being interchangeable. They are both B vitamins,and are equally active. Niacinamide is a component of two vital coenzymes,NAD (nicotinamide adenine dinucleotide) and its phosphate NADP,which are responsible for electron transport in cellular respiration. A deficiency of these and other B vitamins may lead to pellagra,symptomised by severe dermatitis,diarrhoea and depression. Sources of niacinamide include vegetables,lean meat,milk and some cereals (but not maize). Magnification x8 at 35mm size | |
