The atoms of an organic molecule are typically organized around chains of carbon atoms. Organic molecules must contain carbon atoms covalently bonded to hydrogen atoms. 

Organic Molecules

Biomolecules contain a carbon sekelton which is a result of carbon’s unique combination of size and bonding properties, carbon atoms can bind together in large numbers, thus producing a chain. The carbon skeleton of organic molecules can be straight, branched, or ring shaped (cyclic).

Carbon skeleton

Biomolecules contain functional groups which are  groups of atoms within molecules that are categorized by their specific chemical composition and the chemical reactions they perform, regardless of the molecule in which the group is found.some examples of that are commonly used in microbiology include amnio acid groups.

Functional groups

Is an organic molecule that  is found within living organisms they are the building blocks of life and contain chemicals that are composed of oxygen, carbon, hydrogen, sulfur, nitrogen, and phosphorus.

University of Southern Mississippi

The study of the chemistry involved in life processes to explain form and function based on chemical principles.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

COVALENT BONDS
- Covalent bonds - formed when two atoms share one or more pairs of electrons to fill their valence shell
- Bonding valence electrons are attracted by both nuclei in the bond.
- Bond length depends on the nature of the atoms bonded and the number of electrons participating in the bond.
- Carbon-carbon double bonds are generally longer and have less bond energy than do carbon-carbon triple bonds.
- Atoms are held together by these
- Strength and bond length depends on:
Nature of atoms bonded
Number of e- pairs shared
- Greater number of pairs, greater bond energy, lower bond length

INTERMOLECULAR FORCES
- Non-covalent interactions
- Electrostatic interactions
- Ionic interactions
- Non-ionic interactions (electrically neutral)
- Fixed dipole-dipole
- Hydrogen bonds, electronegative
- Fixed dipole-induced dipole
- Induced dipole- induced dipole (london dispersion forces, van der Waals Forces)
