  1. Integrace odborného anglického a německého jazyka do výuky přírodovědných předmětů BIOCHEMIE sestavila PhDr. Marcela Helešicová SPŠCH Brno, 2013

  2. CHEMICAL COMPOSITION OF LIVING ORGANISMS text foreducationofbiochemistry

  3. KEY WORDS • living organisms • livingmatter • chemical elements • biogenic elements • macrobiogenic elements • microbiogenic elements • trace elements

  4. KEY WORDS • biomolecules • inorganic substances • water • carbon dioxide • salts • organic substances • proteins • nucleidacids • saccharides • lipids • biological macromolecules – biopolymers • high molecular substances • low molecular substances

  5. CHEMICAL ELEMENTS IN THE NATURE • 92 elements are naturallypresent in thenature.

  6. ELEMENTS IN THE EARTH´S CRUST • 92 elements • 75 % oxygen andsilicon, 25 % otherelements

  7. BIOGENIC ELEMENTS • About 30 elementscreatethelivingmatter. • Biogenic elements are divided into 3 groups. • Macrobiogienicelements: C, O, H, N, S, P, Na, K, Ca, Mg, Cl, Fe • Four elements represent up to 95 % of living matter. • buildingfunction

  8. BIOGENIC ELEMENTS • Microbiogienicelements: I, Zn, Co, Mn, Mo, Cu • catalyticfunction • Traceelements: Al, F, Si, Se, ………. • catalyticfunction

  9. BIOMOLECULES Living organisms are composed of several types of substances called biomolecules. • Low molecular substances • High molecular substances

  10. BIOMOLECULES • Low molecular substances (Mr < 10 000) • water • carbon dioxide • mineralsalts • aminoacids • lipids • monosaccharides • nucleotides

  11. BIOMOLECULES • High molecular substances (Mr > 10 000) • BIOLOGICAL MACROMOLECULES • proteins • nucleicacids • polysaccharides

  12. Questions and tasks • Which two chemical elements are the most frequent in the Earth’s crust and what is their form? • What are biogenic elements, how do we divide them? • Name 4 basic macroelements. Why are they important? What is their content (percentage) in living organisms? • Name the microbiogenic elements and give examples of their importance. • What is the function which is common for trace elements and what is their content in living organisms?

  13. Questions and tasks 6. Explain the term biomolecule. Which element forms biomolecules? 7. What is the average content of water in organisms and what is its function? 8. Give 3 examples of non-dissociated salts which are present in human body. Give examples of tissues, where the salts are present. 9. Name the basic groups of biopolymers and name the building units they consist of. 10. Give the average percentage of proteins, saccharides, lipids and nucleic acids in living organisms.

  14. THANK YOU FOR YOUR ATTENTION
