What is defination food and protien?

Answer 1

Look at the answer to your other question on this topic...

Answer 2

Question No. = 1 ) what is defination food ?

Answer =Food can be defined as “ Any Organic Molecule that can provide a living organism with

Metabolites AS WELL AS  Metabolic Energy ”

Metabolites = chemical elements that are essential for metabolic activity in the body

Examples = C  , H , N , Mg  , O  etc.

Metabolic energy = Example  ATP

Now let us examine this definition with some examples =

1 ) Sodium Chloride ( NaCl  ) can provide metabolites  Na  and Cl ; but it can not

provide metabolic energy . So ordinary Table Salt ( NaCl ) cannot be food .

2 ) Water ( H2O ) . Like the example above it can provide with the metabolites

Hydrogen and Oxygen.

But water cannot be a source Metabolic Energy . So Water can not be  Food.

No matter how important for life !!!

3 ) Glucose  ( C6 H12  O6 ) . It is most certainly FOOD , as it gives metabolites in the form of

C , H , AND O . And it is a well known fact that it is a source of ATP !!!

4 ) Milk =  Like glucose it is also food , but in liquid form.

Question No.=2) what is defination protien?

Answer =A protein molecule is an organic molecule made up of   Carbon ( C ) ; Hydrogen ( H )

Oxygen (O) and Nitrogen (N) atoms.

No protein can exist with out ANY one of the four mentioned above .

Thus , these are the constant and  integral part of every protein molecule .

The quantity of each one of them is different in different proteins >

In addition , a number  of metal and non-metal atoms are associated with proteins to give them

Specificity.

For example = Chlorophyll is a protein molecule with formula  C55  H72  O5  N4  Mg  !

Thus Mg ( Magnesium ) is associated with it !

Blood Haemoglobin is also a protein and Fe ( Iron )  is associated with it !!

In Invertebrates Haemoglobin is replaced by Haemocyanin and  Fe ( Iron ) is replaced by copper ( Cu )

In Onion and Garlic Sulfur ( S ) is associated with certain proteins that imparts strong smell to them !!
