Exercise 5 INTRODUCTION TO STEREOCHEMISTRY I. Introduction Stereochemistry is concerned with the shapes of molecules and how the differences in shapes can effect the properties and reactions of compounds. Subtle differences in molecular shape have far – reaching consequences and it is probably the field of molecular biology that a full awareness of molecular shapes has emerged. A knowledge of the molecular shapes of such vital compounds as sugars‚ amino acids‚ and proteins is essential

PRODUCTION OF OLIVE OIL INTRODUCTION Olive oil is a pale yellow to greenish oil extracted from the fruit of the European olive tree (Olea europaea L.)‚ which originated in the Mediterranean area. The olive is originally native to the eastern Mediterranean region but the cultivated form is now grown throughout that area and in other parts of the world with Mediterranean-type climates. It hardens at refrigerator temperatures - around 10 degrees F. Today a market certainly exists for olive oil

the earlier Brønsted-Lowry concept. According to Lewis definition‚ acids (electrophiles) are electron pair acceptors and bases (nucleophiles) are electron pair donors. AlCl3 + (CH3)3N ↔Al-Cl3N+(CH3)3In the above example‚ AlCl3 is Lewis acid because it have unoccupied valence orbital and can receive electron pairs from (CH3)3N‚ which is Lewis base. In a Lewis base‚ nitrogen donates an electron pair to an empty valence orbital of an aluminum atom. A curved arrow shows the way of electron-pair flow from

B) Cystine is an example of a nonstandard amino acid‚ derived by linking two standard amino acids. C) Cystine is formed by the oxidation of the carboxylic acid group on cysteine. D) Cystine is formed through a peptide linkage between two cysteines. E) Two cystines are released when a —CH2—S—S—CH2— disulfide bridge is reduced to —CH2—SH. 6. In the binding
