Study Notes
Definition
- A biomolecule is a type of molecule that is present in living organisms
- Biomolecules are the building blocks of life and perform a wide range of functions necessary for life
Types of Biomolecules
-
Carbohydrates: provide energy and structure for cells
- Examples: sugars, starches, cellulose
-
Proteins: perform a wide range of functions, including enzymatic, structural, and transport roles
- Examples: enzymes, hormones, collagen
-
Lipids: provide energy and structure for cells
- Examples: fats, oils, cholesterol
-
Nucleic Acids: contain genetic information and transmit it from one generation to the next
- Examples: DNA, RNA
-
Amino Acids: building blocks of proteins
- Examples: glycine, alanine, serine
Functions of Biomolecules
- Energy production and storage: carbohydrates, lipids, and proteins provide energy for cells
- Structural roles: proteins, carbohydrates, and lipids provide structure and support for cells
- Regulatory roles: proteins, hormones, and neurotransmitters regulate cellular processes
- Transport roles: proteins and lipids transport molecules and ions across cell membranes
- Information storage and transmission: nucleic acids contain genetic information and transmit it from one generation to the next
