Study Notes
Nucleic Acids
- Nucleic acids are polymers made from monomers called nucleotides.
- Composed of elements: Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorus (CHONP).
- Function is to store and transmit genetic information.
- DNA is a type of nucleic acid that contains all instructions for protein synthesis.
- Structure includes a phosphate group, a 5-carbon sugar, and a nitrogenous base.
- Base pairs in DNA include Adenine-Thymine (A-T) and Cytosine-Guanine (C-G).
- RNA serves as a copy of instructions for making a single protein.
Lipids
- Lipids primarily compose cell membranes, forming a barrier that regulates the passage of substances.
- Consist of a hydrophilic phosphate head and two hydrophobic fatty acid tails.
- Steroids are classified as a type of lipid and function in cell communication.
- Lipids are hydrophobic, meaning they do not mix with water, and provide energy storage.
- Elements present in lipids include Carbon, Hydrogen, and Oxygen.
- Phospholipids are essential for cell membrane structure, having both hydrophilic and hydrophobic components.
Proteins
- Proteins are made of amino acids linked through peptide bonds.
- Composed of elements: Carbon, Hydrogen, Oxygen, and Nitrogen (CHON).
- Serve numerous functions, including catalyzing biochemical reactions (enzymes), transporting oxygen (Hemoglobin), and regulating blood sugar (insulin).
- Protein structure is determined by the sequence and arrangement of amino acids.
- There are 20 different amino acids, each with unique side chains which can be polar, non-polar, or charged.
Carbohydrates
- Carbohydrates are key sources of quick energy for both plants and animals, with glucose being a primary energy carrier.
- Polysaccharides such as starch (energy storage in plants) and glycogen (energy storage in animals) are forms of carbohydrates.
- Cellulose, a structural carbohydrate, makes up the plant cell wall.
- Carbohydrates are synthesized by plants during photosynthesis using H2O and CO2.
- Monosaccharides like glucose serve as monomers for carbohydrates, while polymers include starch and glycogen.
General Biomolecule Information
- Polymers are formed from the linking of numerous monomers.
- Different biomolecules serve distinct essential roles in biological systems, including energy storage, structural integrity, and genetic information storage.
