Study Notes
Protein Structure
- Primary Structure: Polypeptide chain of amino acids linked by peptide bonds.
- Secondary Structure: Alpha helix or Beta sheets, stabilized by hydrogen bonds between amino acid backbones.
- Tertiary Structure: Complex 3D folding of the polypeptide chain, stabilized by various interactions (hydrogen bonds, hydrophobic interactions, disulfide bridges, ionic bonds).
- Quaternary Structure: Interaction of multiple polypeptide chains to form a functional protein complex, held together by various bonds (hydrogen bonds, ionic bonds, hydrophobic interactions).
DNA Structure
- Primary Structure: Polynucleotide chain composed of nucleotides linked by phosphodiester bonds.
- Secondary Structure: Double helix formed by two polynucleotide strands held together by hydrogen bonds between complementary base pairs (adenine with thymine, guanine with cytosine).
Cellular Processes
- Ribosome Function: Synthesizing proteins, either free or bound in the endoplasmic reticulum.
- Golgi Apparatus (GA) Function: Modifying, sorting, and packaging proteins.
- Endoplasmic Reticulum (ER) Function: Modifying and transporting proteins made by ribosomes.
- Lipid Synthesis: Endoplasmic reticulum, for lipids and proteins
- Cellular Transport: Facilitated diffusion, active transport as mechanism across cell membranes.
- Detoxification: Endoplasmic Reticulum for detoxification.
- Nucleosome Level: DNA is packed around histone proteins.
- Solenoid Level: Nucleosomes are organized into a tightly wound solenoid structure.
- Third Level (Loop): DNA interacts with scaffolding proteins.
