Amino Acid |
An organic molecule possessing both a carboxyl and amino group. Amino Acids serve as the monomers of polypeptides |
|
|
Protein |
A biologically functional molecule consisting of one or more polypeptides folded and coiled into a specific three dimensional structure |
|
|
Nucleotide |
The building block of a nucleic acid consisting of a five carbon sugar coavalently bonded to a nitrogenous base and one or more phosphate group |
|
|
Nucleic Acid |
A polymer consisting of many nucleotide monomers; serves as a blueprint for proteins and through the actions of proteins for all cellular activities. The two types are Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA) |

|
Difference in meaning between electron orbital and electron shell |
Electron orbital is the shape of space an electron can be found in within the electron shell. The electron shell refers to the energy level and distance from the nucleus. |
|
|
Difference between covalent bonds and Ionic bonds |
Covalent bond is the sharing of a pair of valence electron by two atoms Ionic bond is when an atom either gains or loses an electron from their partner's valence shell creating a bond. |
