Study Notes
Elements of Human Body Mass
- Oxygen, carbon, hydrogen, and nitrogen constitute 96% of the human body's mass.
- Oxygen accounts for approximately 65% of body mass, followed by carbon at about 18%, hydrogen at 10%, and nitrogen at 3%.
Primary Metabolites
- Primary metabolites are compounds directly involved in growth and development, such as amino acids, sugars, and fatty acids.
- An example would be glucose, which serves as a primary energy source in cellular respiration.
Essential Biological Molecules
- Biomolecules that are essential to biological processes are referred to as metabolites.
- These include both primary metabolites for basic physiological functions and secondary metabolites that play roles in plant defense and signaling.
Subfields Studying Biomolecules
- Biochemistry focuses on the chemical processes and substances within living organisms.
- Molecular biology examines the interactions between various cellular systems, including DNA, RNA, and proteins.
Small Biomolecules Examples
- Small biomolecules include amino acids, nucleotides, and simple sugars.
- These molecules serve as building blocks for larger macromolecules such as proteins, nucleic acids, and polysaccharides, influencing numerous metabolic pathways.
