Study Notes
Biomolecules Composition
- Biomolecules are primarily composed of carbon, hydrogen, oxygen, and nitrogen
- Carbon is the primary element in biomolecules due to its unique ability to form long chains and rings with itself and other elements
- This ability allows for the formation of complex molecules with diverse functions
Biological Importance of Carbon
- Carbon's high bonding capacity and stability make it an ideal element for the formation of biomolecules
- Its ability to form long chains and rings allows for the creation of complex molecules with diverse functions
Protein Building Blocks
- The building blocks of proteins are amino acids, which are linked together by peptide bonds
- There are 20 standard amino acids that combine to form proteins
Elemental Composition of Organisms
- Carbon, oxygen, nitrogen, and hydrogen make up more than 97% of the weight of most organisms
- These elements are the primary components of biomolecules and are essential for life
Biological Chemistry
- The chemistry of biological systems is known as biochemistry or biological chemistry
- Biochemistry studies the chemical processes and transformations that occur within living organisms
