Organic Chemistry and Biochemistry are both separate branches of chemistry.
They are so divided because of basic differences and understanding involved.
Organic chemistry deals with organic compounds while the biochemistry deals with the chemistry inside the living beings.
So organic chemistry is more or less related to chemistry while biochemistry is related to biology.
But when we see the chemical substances involved in both of these subjects, it seems both of them are similar and not different.
Hence we will try to understand the similarities and differences in between both of these subjects.
Organic Chemistry and Biochemistry similarities
The chemical in both of these branches appear to have similar elements in their molecular structure. Also, the molecules show stereochemistry based effects. See more similarities in the table below.
|Molecules studied||Carbohydrates, amino-acids, proteins, lipids||Carbohydrates, amino-acids, proteins, lipids|
|Isomers||Knowledge of isomers is studied||isomer information for molecules is studied|
|Common elements in molecules||Carbon, hydrogen, oxygen, nitrogen.||Carbon, hydrogen, oxygen, nitrogen, phosphorus etc.|
|Chemical reactions are dependent on factors like||Heat, pH, humidity,||Temperature, pH, Humidity.|
Organic Chemistry and Biochemistry differences
|Subject covers||Structure, properties of compounds, isomerism, their reactions, synthesis and uses||Covers macro molecules, micro-molecules in the body, enzymes, their reactions|
|Elements involved here specifically||Alkylhalides like carbon tetra chloride, aromatics like benzene||Cofactors of enzymes having heavy metals, vitamins, enzymes|
|Application relate to||Food, daily chemicals, medicines||living body functions, clinical diagnosis|
|Examples of chemical reactions||SN1, SN2 reactions, rearrangement reactions, substitution reactions,||Photosynthesis, TCA cycle, Mevalonic acid pathway, Denova pathway etc.|
|Laboratory reactions include||Identification, synthesis, extractions||Extractions, identification only. No synthesis is involved|
|Pathways of reactions||Mostly smaller pathways.||Lengthy pathways.|
Though the subjects related to each other, the branch of organic chemistry is studied as part of general science while biochemistry is studied for medicine, nursing, botany, zoology etc.
