In histology, several key molecules are routinely studied:
1. Proteins: They are vital for the structure, function, and regulation of tissues and organs. Proteins like collagen, elastin, and keratin provide structural support, while enzymes and receptors are crucial for cellular functions. 2. Lipids: These are essential components of cell membranes and are involved in signaling pathways. They also play roles in energy storage and metabolism. 3. Carbohydrates: Often found as glycoproteins or glycolipids, they are crucial for cell-cell communication and interaction. They also provide energy and structural support. 4. Nucleic Acids: DNA and RNA are the genetic material responsible for storing and transmitting genetic information. They also play roles in protein synthesis and regulation of cellular activities.
