It serves as a carrier of oxygen to the tissues from the lungs by red blood cell haemoglobin, as a transport medium for electrons within cells, and as an integrated part of important enzyme systems in various tissues.

The physiology of iron has been extensively reviewed (1-6). Most of the iron in the body is present in the erythrocytes as haemoglobin, a molecule composed of four units, each containing one heme group and one protein chain. The structure of haemoglobin allows it to be fully loaded with oxygen in the lungs and partially unloaded in the tissues (e. The iron-containing oxygen storage protein in the muscles, myoglobin, is similar in structure to haemoglobin but has Alsuma (Sumatriptan Injection)- FDA one heme unit and one globin chain.

Several iron-containing enzymes, the cytochromes, also have one heme group and one globin protein chain. These enzymes act as electron carriers within the cell and their structures do not permit reversible loading and unloading of oxygen. Their role in the oxidative metabolism is to transfer energy within the cell and specifically in the mitochondria. Iron is reversibly stored within the liver as ferritin and hemosiderin whereas it is transported between different compartments in the body by the protein transferrin.

Iron requirementsBasal iron lossesIron is not actively excreted from the body in urine or in the intestines. Iron is only lost with cells from the skin and the interior surfaces of the body - intestines, urinary tract, and airways.

In children, it is probably more Dexmedetomidine hydrochloride (Precedex)- FDA to relate these losses to body surface. A non-menstruating 55-kg women loses about 0. Earlier studies suggested that sweat Norethindrone Tablets (Deblitane)- Multum losses could be considerable, especially in a hot, Humid climate.

However, new studies which took extensive precautions to avoid the interference of contamination of iron from the skin during the collection of total body sweat have shown that these sweat iron losses are negligible (9). During the first 2 months of life, haemoglobin concentration falls because of Lunesta (Eszopiclone)- FDA improved oxygen situation in Alsuma (Sumatriptan Injection)- FDA newborn infant compared with the intrauterine foetus.

This leads Alsuma (Sumatriptan Injection)- FDA a considerable redistribution of iron from catabolised erythrocytes to iron stores. This iron will cover the needs of the term infant during the first 4-6 months of life and is why iron requirements during this period can be provided by human milk, that contains very little iron.

Because of the marked supply of iron to the foetus during the last trimester of pregnancy, the iron situation is much less favourable in the premature and low-birth-weight infant than in the term infant. An extra supply of iron is therefore needed in these infants even during the first Alsuma (Sumatriptan Injection)- FDA months of life. In the full-term infant, iron requirements will rise markedly after age 4-6 months chem geol amount to about 0.

These requirements are therefore very high, especially in relation to body size and energy intake (Table 39) (10). Because of Alsuma (Sumatriptan Injection)- FDA very skewed distribution of iron requirements in these women, dietary iron requirements are calculated for four levels of dietary iron bio-availability (Table 40). In the first year of life, the full-term infant almost doubles its total iron stores and triple its body weight.

The change in body iron during this period occurs mainly during the first 6-12 months of life. Between 1 and 6 years of age, the body iron content is again doubled. The requirements for absorbed iron in infants Alsuma (Sumatriptan Injection)- FDA children are very high in relation to their energy requirements. For example, in infants 6-12 months of age, about 1.

Because of the very skewed distribution of iron requirements in Alsuma (Sumatriptan Injection)- FDA women, dietary iron requirements are calculated for four levels of dietary iron bio-availability. In the weaning period, the iron requirements in relation to energy intake are the highest of the lifespan except for the last trimester of pregnancy, when iron requirements to a large extent how to manage professional stress to be covered from the Alsuma (Sumatriptan Injection)- FDA stores of the mother (see section on iron and pregnancy).

The rapidly growing weaning infant has no iron stores and has to rely on dietary iron. It is possible to meet these high requirements if the diet has a consistently high content of meat and foods rich in ascorbic acid. In most developed countries today, infant cereal products are the staple foods for that period of life. Commercial products are regularly fortified with iron and ascorbic acid, and they are usually given together with fruit juices and solid foods containing meat, fish, and vegetables.

The fortification of cereal products with iron and ascorbic acid is important in meeting the high dietary needs, especially considering the importance of an optimal iron nutrition during this phase of brain development. Iron requirements are also very high in adolescents, particularly during the period of rapid growth (11).

There is a marked individual variation in growth rate and the requirements may be considerably higher than the calculated mean values given in Table 39. Girls usually have their growth spurt before menarche, but growth is not finished at that time.

Their total iron requirements are therefore considerable. In boys Alsuma (Sumatriptan Injection)- FDA puberty there is a marked increase in haemoglobin mass and concentration, further increasing iron requirements to a level above the average iron requirements in menstruating women (Figure 22).

Iron requirements of boys and girlsMenstrual iron lossesMenstrual blood losses are very constant from month to month for an individual but vary markedly from one woman to another (16).
