1 TASHKENT MEDICAL ACADEMY Department of Bioorganic and Biological Chemistry Bioorganic chemistry I COURSE SUBJECT : Carbohydrates. Structure and chemical properties of monosaccharides. LECTURE №12 LECTURER : PROFESSOR A.D.DZHURAEV

2 PURPOSE OF LECTURES: Generate knowledge stereochemically structure, tautomeric forms and the most important properties of monosaccharides as a basis for understanding their metabolic-cal reactions in the body, and also to study the structural organization of the polysaccharides.

3 The questions of: Classification of carbohydrates and mono- saccharides Stereoisomers of monosaccharides Ring-chain tautomerism and mutarotatsii phenomenon in solutions of monosaccharides Chemical reactions of monosaccharides The biological significance of individual members of the monosaccharides

4 metabolisms solar energy energy photosynthesis, chlorophyll glikolaldegid

5 Triose glyceraldehyde dihydroxyacetone

6 TETROZY erythrose treoza eritruloza

7 Pentose ribosearabinosexyloselikoza

8 KETOPENTOZY D- riuloza D- xylulose

9 Hexose allose tulozaidoza mannoseglucose altrose taloza galactose

10 ISOMERS GLUCOSE L- glucose D- glucose

11 On cyclic hemiacetal colle tollens

12 A method of producing mannose 1. From natural sources (the hydrolysis of starch, cellulose, sucrose, etc.) 2. Aldol condensation of Butlerov AM. 3. Oxidation six and five atomic alcohols

13 Chemical Properties 1. Oxidation

14 2. Restoration polyolhexose

15 3. Getting Glycosides  -D- glucopyranose O-methyl-a-D- glucopyranoside О-methyl-  -D- glucopyranoside

16 4. Getting Ethers  -D-glucopyranose O-methyl-2,3,4,6-tetramethyl- D-glucopyranose 2,3,4,6-tetramethyl-  - D-glucopyranose

17 5. The resulting ester  -D-glucopyranose 1,2,3,4,6-pentaatsetil-D- glucopyranose

18 Value monosaccharides and their derivatives in medicine 6-phosphate  -D- glucopyranose 1-phosphate  -D- glucopyranose 1,6-phosphate  -D- glucopyranose

19 Neuraminic acid

20 Sialic acid acetylN-acetyl - D-neuraminic acidD-mannosamine

21 Value glucuronic acid aspirin salicylic acid elimination of salicylic acid in the form of O-glucuronide

22 Education glucuronide body meprotan excretion in the form of N-glucuronide meprotan
