1. PH of distilled water is 7.0
2. Blood PH is 7.4
3. Osmotic pressure depends only on the number of dissolved particles and is independent of the size of the particle
4. Substances that do not diffuse through membranes are called colliods
5. Substances that diffuse through biological membranes are called crystalloids
6. The process of conversion of water insoluble substances into water soluble substances is called hydrotrophy
7. Rf is the unit of expressing chromatography
8. Rf is the ratio of the distance traveled by the compound to the distance traveled by the solvent.
9. Sucrose is called invert sugar
10. Sucrose is a non reducing sugar
11. Non carbohydrate portion of a glycoside is called aglycone
12. First break down product of glycogen metabolism is Glucose - 1- phosphate
13. Oral insulin is ineffective as it is digested by enzymes
14. Urine of diabetes mellitus patient shows the presence of both glucose and ketone bodies.
15. Urine of starved person shows only ketone bodies
16. Rancidity of fats is prevented by vitamin E
17. Deposition of cerebrosides in liver causes Gaucher's disease
18. Deposition of sphynomyalines in liver causes Niemann-Pick disease
19. Iodine number indicates the degree of unsaturation of fats
20. Cholesterol is detected by Libermann- Burchard reaction and Salkowaki test
21. LDL: Low density Lipoprotein
22. HDL: High Density Lipoprotein
23. Acetyl Co A is the precursor for cholesterol biosynthesis
24. Acetoacetic acid, beta hydroxy butyric acid and acetone are referred to as ketone bodies
25. Ketone bodies are acidic
26. Normal excretion of ketone bodies is 1mg/day
27. 2,4 dinitro phenyl benzene is the reagent used in Sanger's method
28. N terminal amino acid  of a protein is determined by Sanger's method and Edman's method.
29. Biuret test and Ninhydrin tests are the general tests for proteins
30. Peptide groupings are specific to Biuret reaction
31. Reagent used in Edman's method is phenyl isothiocyanate
32. Sugar base combination is called nucleoside
33. Sugar base phosphate combination is called nucleotide
34. Cytosine and thymine are pyrimidine bases
35. Adenine and guanine are purine bases
36. Uracil is a pyrimidine
37. Site other than the active site is called the allosteric site
38. Vitamin A is useful for visual function
39. Vitamin B2 is also called lactoflavin as it was first isolated from milk
40. Histidine amino acid is responsible for the buffering action of haemoglobin.
