Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen. They include sugars (monosaccharides and disaccharides) and starch (polysaccharides). Monosaccharides are single sugars that cannot be broken down further. Common monosaccharides include glucose, fructose, and galactose. Disaccharides are formed when two monosaccharides bond together, such as sucrose, maltose, and lactose. Polysaccharides are long chains of monosaccharides and include starch, cellulose, and glycogen. Plants and animals use carbohydrates for energy storage and structural support.chemistry presentation

Carbohydrates are classified based on their structure and behavior during hydrolysis. Monosaccharides like glucose and fructose can further cyclize to form rings. Glucose forms a 6-membered pyranose ring while fructose forms a 5-membered furanose ring. Carbohydrates can also be classified as reducing or non-reducing based on whether their functional groups are free to participate in reduction reactions. Glucose and fructose both exist as cyclic structures with 留 and 硫 anomers formed by the addition of the hydroxyl group to the carbonyl carbon. Their open chain forms do not fully explain properties like crystallization behavior and lack of reactivity of functional groups.Biomolecules.pptx

Glycolysis is the pathway that converts glucose to pyruvate, generating a small amount of ATP. The liver plays a key role in monitoring and stabilizing blood glucose levels. Glycolysis occurs through three phases: 1) energy investment where glucose is phosphorylated, 2) splitting of a six-carbon molecule into two three-carbon molecules, and 3) energy generation where ATP is produced from the breakdown of the three-carbon molecules. The pathway generates 2 ATP per glucose under anaerobic conditions and up to 8 ATP per glucose under aerobic conditions using shuttle pathways to further oxidize NADH in the mitochondria.Enzymes.pptx

The citric acid cycle (Krebs cycle or TCA cycle) is the most important metabolic pathway for energy production in the body. It occurs in the mitochondrial matrix and involves the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins to produce carbon dioxide, water, and the electron carriers NADH and FADH2 to drive ATP production. The cycle generates 12 ATP per acetyl-CoA molecule oxidized and also provides precursors for various biosynthetic pathways. Key steps include the condensation of acetyl-CoA with oxaloacetate to form citrate, followed by oxidative decarboxylations and hydrations that regenerate oxaloacetate and release carbon dioxideAmino acids.ppt

Amino acids are organic compounds that contain amino and carboxyl groups. They are the building blocks of proteins. There are 20 standard amino acids that make up proteins. Amino acids can be classified based on their structure, including whether they are nonpolar, polar, or have other functional groups. The classification determines each amino acid's properties and role in protein structure and function. Some amino acids are essential to obtain through diet, while others can be synthesized in the body. Amino acids have optical activity, acid-base properties, and can absorb ultraviolet light depending on their structure. They generally exist as zwitterions at physiological pH.Basics Titration.pptx

Titration involves slowly adding a solution of known concentration (the titrant) to a solution of unknown concentration until the reaction reaches the equivalence point or endpoint, which is often indicated by a color change when using an indicator.
Some key aspects of titration covered are the definition of titration, types of neutralization reactions, titration procedures, uses and properties of acid-base indicators, and different titration curves produced from strong acid-strong base, weak acid-strong base, and weak base-strong acid titrations.
Titration is widely used in laboratories due to advantages such as being a fast, accurate, precise, and affordable analytical technique that does not require highly specialized skills or knowledge to perform.PRECIPITATION TITRATTION.ppt

1. Precipitation involves combining two ionic species to form an insoluble product, forcing the reaction to completion. For precipitation reactions to be useful in titrimetric analysis, the precipitate must be insoluble and form rapidly and quantitatively without interference from adsorption effects. The equivalence point must also be detectable.
2. Factors that affect solubility include common ion effect, temperature, solvent, and pH. Solubility product constants describe the solubility equilibrium of slightly soluble salts. Fractional precipitation determines which salt will precipitate first when multiple anions are present.
3. Direct and indirect precipitation titrations can be used. Direct titrations detect the equivalence point by formation of a coloredNON AQUEOUS TITRATION.pptx

Non-aqueous titrations are used for substances that are too weakly acidic or basic to titrate in water. The technique involves dissolving the substance and titrant in a non-aqueous solvent. There are four classes of non-aqueous solvents: protogenic solvents enhance basicity; protophillic solvents enhance acidity; amphiprotic solvents can act as acids or bases; and aprotic solvents are neutral. Common indicators used for non-aqueous titration include crystal violet, quinaldine red, and alpha-naphthal benzene.

Carbohydrates.ppt
- 1. Mrs. Prajakta B. Kothawade Assistant Professor, PES Modern College of Pharmacy, for ladies, Moshi, Pune
- 2. Carbohydrates are Polyhydroxy aldehydes or ketones, or substances that yield such compounds on hydrolysis. General formula : (CH2O)n
- 3. Monosaccharides carbohydrates that cannot be hydrolyzed to simpler carbohydrates; eg. Glucose or fructose. Oligosaccharides carbohydrates that can be hydrolyzed into a few monosaccharide units; eg. Sucrose or lactose Polysaccharides carbohydrates that are polymeric sugars; eg Starch or cellulose
- 4. Monosaccharides Contains 3-9 carbon atom sugars.
- 7. Ketone Aldehyde 4 Tetrose Tetrulose 5 Pentose Pentulose 6 Hexose Hexulose 7 Heptose Heptulose 8 Octose Octulose Number of carbons
- 8. Oligosaccharides contains 2-10 monosaccharide units joined by glycosidic bonds. -OH group of one monosaccharide joined to -OH group of another monosaccharide . Links may be a or b Link around glycosidic bond is fixed but anomeric forms on the other C-1 are still in equilibrium.
- 10. Polysaccharides are complex carbohydrates made up More than 10 linked monosaccharide units. Nomenclature: Homopolysaccharide-a polysaccharide is made up of one type of monosaccharide unit. Heteropolysaccharide-a polysaccharide is made up of more than one type of monosaccharide unit. Starch and glycogen are storage molecules Chitin and cellulose are structural molecules Cell surface polysaccharides are recognition molecules
- 12. Some types of polysaccharides 1.Starch Starch is a storage compound in plants, and made of glucose units It is a homopolysaccharide made up of two components: amylose and amylopectin. Most starch is 10-30% amylose and 70-90% amylopectin
- 13. Amylose a straight chain structure formed by 1,4 glycosidic bonds between 留-D-glucose molecules. H O OH H OH H OH CH2OH H O H H OH H OH CH2OH H O H H H O O H OH H OH CH2OH H H H O H OH H OH CH2OH H OH H H O O H OH H OH CH2OH H O H 1 6 5 4 3 1 2 amylose Structure of Amylose Fraction of Starch
- 14. The amylose chain forms a helix. This causes the blue colour change on reaction with iodine. Amylose is poorly soluble in water, but forms micellar suspensions Amylose
- 15. Amylopectin-a glucose polymer with mainly 留 -(14) linkages, but it also has branches formed by 留 -(16) linkages. Branches are generally longer than shown above.

- 16. Amylopectin causes a red- violet colour change on reaction with iodine. This change is usually masked by the much darker reaction of amylose to iodine. Amylopectin Amylopectin
- 17. Starch therefore consists of amylose helices entangled on branches of amylopectin.
- 18. 2 Glycogen Storage polysaccharide in animals Glycogen constitutes up to 10% of liver mass and 1-2% of muscle mass Glycogen is stored energy for the organism Similar in structure to amylopectin, only difference from starch: number of branches Alpha(1,6) branches every 8-12 residues Like amylopectin, glycogen gives a red-violet color with iodine
- 19. glycogen
- 20. 3 Cellulose The 硫-glucose molecules are joined by condensation, i.e. the removal of water, forming 硫-(1,4) glycosidic linkages. The glucose units are linked into straight chains each 100-1000 units long.
- 22. Cellulose
