Stereochemistry of Carbohydrate

Stereochemistry Saccharides with identical functional groups but with different spatial configurations have different chemical and biological properties. Stereochemisty is the study of the arrangement of atoms in three-dimensional space. Stereoisomers are compounds in which the atoms are linked in the

Chain and Ring Structure of glucose

Chain and Ring Structure Many simple sugars can exist in a chain form or a ring form, as illustrated by the hexoses. The ring form is favored in aqueous solutions, and the mechanism of ring formation is similar for most

Verious Sterilization technique in the medical laboraotry

PHYSICAL TECHNIQUE This technique involved radiation dry heat, moisture, boiling water, steam at 100ºC, and steam under pressure. Radiation: This method involved the used electromagnetive radiation in the microbiology laboratory to achieve this sterilization goal. In these techniques, the source

Mutarotation of D-glucose

MUTAROTATION When aldehyde is first dissolved in water and the solution is put in optical part so that the surface polarized light passed. The first optical rotation show by sugar slowly change it way until it form a fixed constant

The word ‘Carbohydrates’ define as a group of organic compounds, starting from Simple sugars monosaccharide to complex sugars polysacchacharides,

INTRODUCTION The word ‘Carbohydrates’ define as a group of organic compounds, starting from Simple sugars monosaccharide to complex sugars polysacchacharides, that make up some of the essential structures in the biosphere. Carbohydrates is one of the most available biomolecules on

Property of protein

Properties of Proteins   Proteins are known to have the following major properties:   1.  Proteins have varying molecular weights. The molecular weights of insulin,  haemoglobin and immunoglobulins are 5700, 68000 and 150000 respectively.  2.  Absorption of ultraviolet light. They strongly


This is the present of asymmetric carbon atom in any compound. The present of asymmetric carbon atom in a compound give rise to formation of isomer of that compound, such will be identical in composition but differ in partial configuration;


Glucose is one of the important carbohydrates in the field of bimolecular chemistry. Glucose has a general formula which is; (C6H12O6), with this formula, it renders glucose to be called hexose sugar. In a general properties reference to glucose it


Chiral carbon is a carbon in a carbohydrate chain that does not have a repetitive of 2 or more of same atom bind to it chain In the above diagram it will be observed that there is no repetition of any atom attached


Carbohydrate is biochemical substance in living organism. Carbohydrate is found in large number of food, such as sugar, milk, jams potatoes, cereal, bread, etc. Many more of carbohydrate found in the universe is known as biomolecule. All sugar is carbohydrate,


Carbon is atom is found group 14, in a complete form of periodic table but basically is found in group four when periodic are arranged base on it first twenty  element. carbon exist in two allotrope form which are diamond
