Chemical Constitution

Carbohydrates are, as their name implies, compounds of carbon and water, (C – H ₂O) _N, distinguished from one another by the number of units and the arrangement of elements in each molecule. The commonest mono-saccharine in plants and animal are hexodes, compounds containing six units (C – H ₂O)₆ or C₆ H₁₂ O_6.O f these glucose, fructose, and galactic, distinguished from one another by their molecular configuration, have the greatest physiologic significance. In plants these units are usually coupled together, with the loss of one molecule of water, to from disaccharides, with the general formula 2 (C₆ H₁₂ O₆) – H ₂O = C₁₂ H₂₂ O_11.

The commonest of these are maltose = 2 glucose; sucrose = glucose + fructose; and lactose = glucose + galactic. Glucose is also polymerized in the vegetable kingdom into starches and in animal tissues to glycogen, multiples of enormous magnitude with the general formula (C₆ H₁₀ O₅), one molecule of water being lost at each point of union between the molecules of glucose. Pentose, 5 – carbon monosaccharide, C₅ H₁₀ O₅ is found in nucleic acids in the body.

Actually, using eyeglasses is not the only solution; contact lenses are the other things that can be used to support your visions. Some people choose it for the more practice using; just by attaching it to the eyes. However, it is also not always suitable for all people for it can cause some allergic to the eyes. So, do you think you have another option to make better your vision? The answer is yes. When the eyeglasses and contact lenses don’t give good solution for you; it will be a great idea for you to repair your vision through LASIK.

Dr. G. Peyton Neatrour is an optometrist that can help you to have the LASIK. He is the expert one in this eyes correcting surgery with laser. He knows best about the uncomforted feeling of you while using eyeglasses or contact lenses; because he also ever felt that then got repaired it though LASIK.. Now it is your turn to have a better vision; the doctor will do the LASIK best for you.

A relatively short period of chorine deficiency or the administration of excessive amounts of sodium chloride to young rats results in the development of hypertensive cardiovascular disease, and the questions has been raised as to whether comparable conditions might induce a similar condition might induce a similar condition in the human.

The frequency with which deposits of cholesterol are observed in diabetes, renal disease, hypothyroidism, and liver disease has focused attention on this normal constituent of the diet as a possible contributor to the abnormalities noted in these conditions, and particularly as a cause of atherosclerosis. In support of this supposition is the experimental induction of atherosclerotic lesion in rabbits, chicks, and cubes monkey, hamsters, and guinea pigs when fed diets which cause hypercholesterolemia. In dogs, similar lesion may be induced when such feedings are associated with the administration of an antithyridal drug. On the other hand, since the body normally forms cholesterol in large amounts from the acetate derived from fat and carbohydrate , one might question whether variation in the exogenous supply of this substance play a role in the pathogenesis of atherosclerosis. The observed deposition of cholesterol in atherosclerosis may reflect an intrinsic defect n the aging or diseased vessel rather than be a result of the ingestion of cholesterol or other lipids in excessive amounts. The beneficent effect of caloric restriction in the management of cardiac disease and diabetes is more firmly established.

Malnutrition may result not only from deficiencies of the diet but also from (1) faulty digestion of the food; (2) disorders of the liver and pancreas, discussed in Part IV; (3) increased requirements of the body, as in pregnancy, lactation, hyperthyroidism, etc; or  (4) an increased loss of nutrients, as in glycosuria, albuminuria, diarrhea, etc.

The body weight reflects poorly the state of nutrition, since the intake in large amount of calorically rich material, such as carbohydrate or alcohol, may result in actual overweight in the face of malnutrition. The state of hydration of the tissues must also be taken into account, since inanition may be accompanied by dehydration (as in diarrheal diseases) or by over hydration (as in beriberi),. Correction of the diet in an emaciated individual may be followed, accordingly, by a temporary loss of weight due to the excretion of excessive stores of water.

The diagnosis of under nutrition may be suspected from the dietary history. When pronounced, malnutrition is evident from the physical findings as manifested in the body weight, skin, eyes, mouth, nervous system, etc, and by such special laboratory examination as the x-ray of the skeleton and heart, and studies of the composition of the blood. The detection of early stages of deficiency may be difficult, since these are manifested by nonspecific functional disturbances common to many illnesses.
