Tests for various biological molecules and their properties

The Various Biological Molecules

1. Protein

Structure:

The protein is a complex, high-molecular-weight commingle organic compound made up of amino acids joined by peptide bonds.

Function:

umteen proteins are enzymes or subunits of enzymes, catalyzing chemical reactions. Some other proteins form the struts and joints of cytoskeleton. Many membrane proteins function as binding proteins for kiosk to cell adhesion, transport, signal molecules and for defence.

2. Fats

Structure:

Lipids contain of just large regions of carbon, total heat. They are all in all hydrophobic and not soluble in water.

Function:

Serves as interject for energy, insulation, formation of plasma membrane, buoyancy for animals, form a horizontal surface around organs and hence serve as a layer of protection.

3. Reducing peag

Structure:

It is hexagonal .it is carbon + water. They are sugar polymers. Reducing sugar is an organic compound that is composed of tinges of carbon, hydrogen and atomic number 8 in the ratio of 1 carbon atom: 2 hydrogen atoms: 1 oxygen atom. glucose, one interpreter of reducing sugar, has six carbon atoms.

Function:

It provides energy and regulates blood glucose.

4. Starch

Structure:

Starch consists of 2 molecules, amylase and amylopectin, which both comprise of 1-4 glucose linkages. It is also a compound containing carbon, hydrogen, oxygen in the ratio 1:2:1

Function:

It provides us with energy.

Aim of the experiment

To interrogatory for the presence of starch, fats, reducing sugars in the bread, meat, scramble eggs and go steady whether the big breakfast is a healthy breakfast for deal to consume.

Experimental procedure

1 Test for lipids

BREAD

Step 1: grind the bread into small pieces which go off put into the test-tube

Step 2: put the small pieces of bread into the test-tube

Step 3: add in ethanol into the test-tube

Step 4: add In water into the test-tube as well

Step 5: shake...
