Chemistry for Pharmacy Students: General, Organic and by Satyajit Sarker, Lutfun Nahar

By Satyajit Sarker, Lutfun Nahar

"This booklet has succeeded in protecting the elemental chemistry necessities required via the pharmaceutical technology student… the undergraduate reader, be they chemist, biologist or pharmacist will locate this a fascinating and helpful read." –Journal of Chemical Biology, might 2009

Chemistry for Pharmacy Students is a student-friendly advent to the major components of chemistry required via all pharmacy and pharmaceutical technology scholars. The ebook offers a accomplished review of a few of the components of basic, organic items chemistry (in relation to drug molecules).

Clearly established to augment pupil realizing, the booklet is split into six transparent sections. The e-book opens with an outline of normal elements of chemistry and their value to trendy lifestyles, with specific emphasis on medicinal purposes. The textual content then strikes directly to a dialogue of the strategies of atomic constitution and bonding and the basics of stereochemistry and their importance to pharmacy- on the subject of drug motion and toxicity. numerous points of aliphatic, fragrant and heterocyclic chemistry and their pharmaceutical significance are then lined with ultimate chapters natural reactions and their functions to drug discovery and improvement and usual items chemistry.

* available creation to the most important parts of chemistry required for all pharmacy measure courses
* student-friendly and written at a degree compatible for non-chemistry scholars* comprises studying ambitions firstly of every chapter
* specializes in the actual houses and activities of drug molecules

Sample text

So, to derive Lewis structures for most molecules the following sequence should be followed. (a) Draw a tentative structure. The element with the least number of atoms is usually the central element. (b) Calculate the number of valence electrons for all atoms in the compound. (c) Put a pair of electrons between each symbol. (d) Place pairs of electrons around atoms beginning with the outer atom until each has eight electrons, except for hydrogen. If an atom other than hydrogen has fewer than eight electrons then move unshared pairs to form multiple bonds.

Surface tension, viscosity and vapour pressure. Hydrogen bonding occurs with hydrogen atoms covalently bonded to oxygen, fluorine or nitrogen, but not with chlorine, which has larger atom size. The strength of a hydrogen bond involving an oxygen, a fluorine or a nitrogen atom ranges from 3 to 10 kcal/mol, making hydrogen bonds the strongest known type of intermolecular interaction. p. 100  C). 6 SIGNIFICANCE OF CHEMICAL BONDING IN DRUG–RECEPTOR INTERACTIONS 31 within a molecule. Hydrogen bonding is usually stronger than normal dipole forces between molecules, but not as strong as normal ionic or covalent bonds.

We can easily identify the only difference in the following structures, which is the orientation of the hydroxyl group at the chiral centre. In the case of D-glyceraldehyde the –OH group on the chiral carbon is in on the right hand side, whereas in L-glyceraldehyde it is on the left. In the D and L system, structures that are similar to glyceraldehyde (at chiral carbon) are compared, for example 2,3-dihydroxypropanoic acid. H O H * OH CH2OH (+)-D-Glyceraldehyde H HO O * H CH2OH (−)-L-Glyceraldehyde HO O HO O H * OH CH2OH HO * H CH2OH D-2,3-dihydroxypropanoic acid The -OH on the chiral carbon (*) is on the right D-2,3-dihydroxypropanoic acid The -OH on the chiral carbon (*) is on the left One must remember that there is no correlation between D and L configurations, and (þ) and (À) rotations.
