Download The subcomponents of biological molecules and their sequence

The subcomponents of biological molecules and their sequence determine the
properties of that molecule
Molecule’s function and properties are determined by its shape and
subcomponents. An amino acid sequence in a polypeptide determines the property
of the protein molecule. A carbohydrate’s property can be determined by the
structural formula. The number of hydrogen and single bonds in a fatty acid can
determine whether the fat is saturated or unsaturated. From these phenomenons
we can see that subcomponents of biological molecules and their sequence
determine the properties of that molecule.

These are structural formulas of α and β glucose rings. It’s noticeable that the
α and β glucose rings have different structures as in the position of OH atoms. These
differences lead to the differences in the polymer chains the α and β glucose rings
make. Starch is a polymer made out of α glucose rings and has the purpose of
storage. However, the cellulose made out of β glucose rings has a different purpose.
It has a structural purpose rather than a storage purpose.

Protein’s property is really dependent on its subcomponents; for protein
everything matters. The R group is vital in proteins because the R groups of amino
acids are the components that make the final shape of the protein and the function
of the protein. The bonding in the tertiary structure is all determined by the R
group. Also the primary structure of polypeptide chain is important because if any
sequence goes wrong it will lead to a mutated protein such as the sickle cell
hemoglobin.
Therefore by changing a subcomponent that has the same type of R group or
somewhat similar in terms of hydrophobic, hydrophilic, acidic, and basic can
successfully maintains the original function of the protein. DNA is also like protein if
thymine is replaced by uracil and the deoxyribose is replaced by ribose then the
sequence will maintain its properties except that it’s changed to RNA.
When a subcomponent is changed the molecules properties but may
maintain it properties the subcomponent has relatively similar properties.
