What is the approximate C:H:0 and ratio in each of the following types of macromolecules? What 2 functional groups are present in every amino acid that compose proteins? What are the 3 components of nucleotide, the building blocks of nucleic acids? Put your answers in the appropriate box. Proteins Nucleic acids Carbohydrates Lipids Functional groups found in amino acids 3 compone of Nucle acids 2. List, in order, and define the four structures of a protein.

Answer 1

Ans)

C:H:O ration in -

Carbohydrates = 1:2:1

Lipids = 2:1:0.5

Proteins = 1:6:1

Nucleic acids =1:1:1

Two functional groups are present in amino acids are amino group (NH₂) and carboxylic acid ( COOH ^-​​​​​​) group. Only the alkyl chain differs in all the amino acids.

The three components of a nucleotide is

Sugar ( such as deoxyribose sugar)

Nitrogenous base ( the four nucleotides Adenine, guanine, cytosine and thiamine and yracil in case of RNA)

Phosphate group.

2) the four structures of protein are -

Primary structure - it is essentially a linear structure of amino acids linked together.

Secondary structure - alpha helices and beta pleated sheets.

Tertiary structure.- is a three dimensional arrangement of polypeptide chains.

Quarternary structure - spatial arrangement of two or more polypeptide chains in respect to one another.
