BIOMOLECULES | CLASS 11TH NOTES HANDWRITTEN

Polynucleotide(DNA)----->Biomolecules (present at nuclear region.)

Cell contains:-

1.Carbohydrates

2.lipids(they form plasma membrane)

3.Fatty acids

4.Proteins(different kind)

That is, biomolecules will be present in protoplasm(nucleoplasm+cytoplasm).

This was all about biomolecules.

Now we will talk about relative Abundance

Take a microbial culture or microbial paste 

When comparing cells with the earth crust we will find the maximum of the elements present are the same such as :- 

C

H

O

N

S

Living organisms more concentration

Si

Non living more concentration on earth crust

Chemical Analysis

Alevora

Mortar and pestle grind(centrifugation) to form sullary 

In the presence of a chemical trichloroacetic acid

CH3COOH replacing hydrogens by chlorine ----------CCl3COOH

 We will get paste we will put them in cloth and we will try to filter 

The soluble particle or the particle which passes by are called filtrate(filtre ho gaya)

Cellular pool - all kinds of chemicals or all kinds of molecules present in a particular cell.

Which will be filtered will be filtrate and which are retained are called retainted.

Micro

18 - 800 Da

Take amino acid 

Most of them are formed of different monomers 

Macro 

More than 1000 Da

Most of them are formed of polymers.

Different amino acid form protein

Combine different monosaccharide to form polysaccharide

Lipid is a macromolecule because acid is found in insoluble form.

Nucleotide combines with  phosphate bonds to form nucleic acid(DNA and RNA).

Lipid weight is low(18-800) then also it is found in macro

First of all it is found soluble.

All things  are made up of monomers example 

Repeat monomer will get polymer 

Repeating 1 amino acid will get protein.

Repeat nucleic acid will get nucleic acid

Fatty acid and glycerol they are not having particular monomer
