Ethanol Metabolism
Ethanol metabolism occurs primarily in the liver through alcohol dehydrogenase and the microsomal ethanol oxidizing system, generating acetaldehyde and NADH.
BiologyHormonal Regulation of Metabolism
Hormones coordinate metabolic activity across different tissues, ensuring that energy supply meets demand through the actions of insulin, glucagon, and other regulatory hormones.
BiologyMetabolic Integration
Metabolic integration describes how the body coordinates the metabolic activities of different organs to maintain energy homeostasis across fed and fasting states.
BiologyMetabolism in Special Tissues
Different tissues have specialized metabolic profiles that reflect their unique functions, from the liver's central role in nutrient processing to the heart's reliance on fatty acids.
BiologyNucleotide Metabolism
Nucleotide metabolism encompasses the synthesis and degradation of purines and pyrimidines, which are essential for nucleic acid synthesis, energy transfer, and signaling.
BiologyChromatin Immunoprecipitation
Chromatin immunoprecipitation is a method for mapping protein-DNA interactions in the genome, identifying where transcription factors and histone modifications are located.
BiologyCRISPR Applications Beyond Cas9
CRISPR technology has expanded far beyond genome editing with Cas9 to include base editing, prime editing, gene regulation, and diagnostic applications.
BiologyDNA Microarrays and Gene Expression Analysis
DNA microarrays allow simultaneous measurement of the expression levels of thousands of genes, providing a genome-wide view of cellular transcriptional activity.
BiologyEMSA and DNA Footprinting
EMSA and DNA footprinting are classic methods for studying protein-DNA interactions, revealing binding affinity, specificity, and the precise nucleotides contacted by proteins.
BiologyFlow Cytometry
Flow cytometry is a laser-based technology that rapidly measures physical and chemical properties of individual cells or particles in a fluid stream.
BiologyYeast Two-Hybrid System
The yeast two-hybrid system detects protein-protein interactions in living yeast cells by reconstituting a functional transcription factor.
BiologyHeme Biosynthesis and Degradation
Heme is an iron-containing porphyrin that serves as the prosthetic group for hemoglobin, myoglobin, cytochromes, and other essential proteins.
