II. Лексико-грамматическая работа.

Занятие 16.

I. Устный опрос по теме: Белки.

Текст стр. 24 “Proteins " (уч.пос "English for Pharmaceutists”)

1. Translate the following word combinations:

To result in

Сomplex nitrogenous organic substances

Еxcellent nutrient media for micro-organisms

To be coagulated by heat

To be degraded

Insolubility in water

Enzyme activity

Intermolecular change.

 

2. Translate the following sentences, ask special questions to them:

1. Белки классифицируются по их растворимости.

2. Белки формируют существенную часть всех живых тканей.

3. Если внутримолекулярные изменения необратимы, белки денатурируют.

 

3. Answer the following questions:

1) What are the proteins?

2) In what state are the proteins present in nature?

3) How are the proteins classified?

4) Why is the presence of protein in a galenical preparation usually undesirable?

 

Ключи:

1. Translate the following word combinations:

Приводить к

Комплексные азотосодержащие органические вещества

Превосходная питательная среда для микроорганизмов

Сворачиваться под воздействием тепла

Разлагаться

Нерастворимость в воде

Активность ферментов

Внутримолекулярное изменение

 

2. Translate the following sentences, ask questions to them:

1. The proteins are classified according to their solubility.

How are the proteins classified?

2. The proteins form the essential part of all living tissues.

What do the proteins form?

3. If intermolecular changes are irreversible, the proteins are denatured.

When are the proteins denatured?

 

3. Answer the following questions:

1. Proteins are complex nitrogenous organic substances of high molecular weight which form an essential part of all living tissues.

2. In living tissue, proteins are associated with water and are present in the colloidal state.

3. The proteins are classified chiefly according to their solubility: thus albumins are soluble in water while globulins are insoluble in water but soluble in dilute salt solutions.

4. Since solutions which contain protein form excellent nutrient media for micro-organisms, the presence of protein in a galenical preparation is usually undesirable.

Can we survive?

We humans can expect disaster in the mid-21st century. According to Kiev geneticist V.A.Kordyum, everyone will be systematically ill from childhood. The smallest changes in conditions of life will result in widespread death. The reason is that human genes tend to mutate. Some of these changes reduce vitality. People become sickly and unable to bear children, or if they do so their children inherit their diseases and leave no progeny. Under normal conditions bad genes are excluded from the human race through natural selection.

. Bad genes occur frequently, and all human genes change in about 1,000 generations. Thus all the progeny of Adam and Eve would have died after 25,000 years if they had had ideal heredity. This was prevented by natural selection.

The advances of civilization increasingly interfere with natural selection. Many hereditary interfere with natural selection. Many hereditary diseases can now be cured and carriers of bad genes transmit them to succeeding generations. Thanks to the progress of medicine, which preserves vitality in the carriers of bad genes, human genetic degradation increases. Environmental pollution and the newly discovered chemicals we all consume add to the impact on human health due to be felt by the mid-21st century.

V.A.Kordyum thinks the solution lies in giving top priority to the development of genie therapy. This already enables in vitro conception and embryo sex programming. In the future it will be possible to repair human genes. But will this development come too late?
