18 Questions
What are the three laws of crystallography?
Law of constancy of interfacial angles, Law of rationality of indices, Symmetry elements in crystals
What is the Bragg equation used for?
X-ray diffraction by crystals
What are the characteristics of polymers?
Polymers can be classified as plastics, elastomers, or fibers.
How can the molecular mass of polymers be determined?
Through methods like Viscosity, Light scattering, Gel permeation chromatography, Osmometry, and Ultracentrifuging.
What are the different techniques of polymerization?
Addition (chain-growth) polymerization and Condensation (step-growth) polymerization
Give examples of inorganic polymers.
Silicones and phosphazenes
What is the role of -OH group in drug molecules?
The -OH group can provide hydrogen bonding interactions, affecting the drug's solubility and bioavailability.
How is the primary structure of a protein determined?
The primary structure of a protein is determined by methods like DNFB and Edman degradation to identify the N-terminal amino acid.
Explain the mechanism of enzyme action.
Enzymes act by binding to the substrate at the active site, facilitating the conversion of substrate into product.
What is the definition of a space lattice in solid state chemistry?
A space lattice refers to the regular arrangement of points in three-dimensional space that represents the crystalline structure of a solid.
How do enzyme inhibitors affect enzyme activity?
Enzyme inhibitors can block the active site of an enzyme, preventing substrate binding and thus inhibiting the enzyme's catalytic activity.
What is the significance of zwitterion structure in amino acids?
The zwitterion structure of amino acids allows them to act as both acids and bases, influencing their interactions in biological systems.
What is the mechanism of mutarotation?
The mechanism of mutarotation involves the interconversion between alpha and beta forms of a sugar in solution.
Explain the Lobry de Bruyn-van Ekenstein rearrangement.
The Lobry de Bruyn-van Ekenstein rearrangement involves the conversion of aldoses into ketoses by rearrangement of functional groups.
What are the constituents of Nucleic Acids?
The constituents of Nucleic Acids are Adenine, Guanine, Thymine, and Cytosine.
Explain the Watson-Crick model of DNA.
The Watson-Crick model of DNA describes the double helix structure of DNA with complementary base pairing.
What is the process of Transcription in DNA?
Transcription is the process of synthesizing an RNA molecule using a DNA template.
Describe the Basic Retrosynthetic approach in drug design.
The Basic Retrosynthetic approach involves breaking down a complex molecule into simpler starting materials.
Test your knowledge on the Chemistry of Carbohydrates, focusing on the classification, properties, structures, and interconversions of sugars like Glucose and Fructose. Topics include reducing and non-reducing sugars, epimers, mutarotation, anomers, Fischer's proof, Haworth projections, and more.
