Thanks kriti...?

Kriti Sharma 5 years, 9 months ago

Bio molecule...... bio means living .........molecules.means substances .examples of biomolecules are.... polysaccharides .....saccharides stands for sugars .............polysaccharides means long molecules of sugar ......ok like sucrose which is formed from glucose and fructose........ galactose from glucose and lactose..... ok sometimes questions are asked the like.......what would be the result of the hydrolysis of sucrose ........answer is glucose and Fructose.......... reducing sugars are those carbohydrates which contain free aldehyde aur Ketone group ..........and hence reduce fehling solution and tollens reagent.......... non reducing sugar are just opposite ......example sucrose....... remember whenever we treat glucose with hydrogen iodide we get a linear hexane......... there are two types of amino acids ..........essential...... non essential essential .....1 one are not produced by the body .......non essential one are produced by the body .......types of proteins fibrous proteins which are insoluble in water ........Globular proteins are soluble in water.......... constituents of nucleic acids are pentose sugar ......phosphoric acid...... nitrogenous base............ nitrogenous base of two types....... pyrimidines cytosine thymine uracil .......purine adenine and guanine ........ two types ........fat soluble vitamins vitamin A D E K are fat soluble........ and a stored in liver and adipose tissues...... water soluble Vitamin B and C....... remember the question........ why Vitamin C can not be stored inside our body the reason is......... because it is a water soluble vitamin and hence it is excreted out from the body regularly and hence we need a regular supply of Vitamin C....... come to the the chemical names of some vitamins Vitamin B1 thiamine ........vitamin B2 riboflavin.......... Vitamin B6 pyridoxine......Vitamin C ascorbic acid........ so questions which came in last year and important one are what is glycogen............ as the name suggest glyco means related to glucose and is a polymer of glucose and glycogen is stored in animal bodies in the same way cellulose is stored in plant bodies...... difference between nucleoside and nucleotide.......hope it helps you if it helped please write??

Manjay Jha 5 years, 9 months ago

Pura biomolecules how can i explain it to you. I can just say that learn the difference btw Amylose and Amylopectin.....products of sucrose, lactose and maltose when there are hydrolysed... What is nucleoside and nucleotide...diffrence btw rna and dna...glycogen and starch...invert sugar...denaturation of protein...essential non essential amino acids... alpha helix and beta helix...peptide linkage...types of rna found in the cell!!! I think that's enough.

What is the reason for stability of colloidal sols?

Posted by Kriti Sharma 5 years, 9 months ago

CBSE > Class 12 > Chemistry

2 answers

Ďãřşháñăã Yadav ? ? ? 5 years, 9 months ago

The main reason for stability of colloidal sol is that all colloidal particles in the sol carry the same charge hence they repel each other and cannot coagulate.

Yogita Ingle 5 years, 9 months ago

There are two main reasons for the stability of colloidal sols:
Solvation: Colloidal particles are covered by a sheath of liquid in which they are extensively solvated, thereby providing stability.

Electrostatic stabilisation: Presence of equal and similar charges on the colloidal particles prevents coagulation of the colloidal sol.
