  • Lipid Hormone
    Hydrophobic signaling molecule derived from cholesterol, capable of diffusing through plasma and nuclear membranes to affect cellular processes.
  • Steroid Hormone
    Type of lipid hormone, hydrophobic and cholesterol-derived, often binds to intracellular receptors to regulate gene expression.
  • Cholesterol
    Molecule serving as the precursor for steroid hormones, enabling their hydrophobic nature and membrane diffusion.
  • Hydrophobicity
    Property allowing molecules to pass through lipid bilayers, crucial for lipid hormones to access intracellular targets.
  • Plasma Membrane
    Cellular barrier that lipid hormones can traverse directly, unlike non-lipid hormones which require receptor-mediated entry.
  • Nuclear Membrane
    Barrier surrounding the nucleus, permeable to lipid hormones, enabling direct regulation of gene expression.
  • Intracellular Receptor
    Protein located within the cytoplasm or nucleus, activated by lipid hormones to modulate cellular responses.
  • Extracellular Receptor
    Protein embedded in the cell membrane, interacts with non-lipid hormones and some lipid hormones to initiate signaling.
  • Signal Transduction
    Process by which hormone binding to a receptor triggers a cascade of cellular events, leading to a specific response.
  • Metabolic Response
    Cellular change in metabolism resulting from hormone signaling, often influenced directly by lipid hormones.
  • Gene Expression
    Regulation of transcription and translation in cells, frequently altered by lipid hormones entering the nucleus.
  • Paracrine Hormone
    Signaling molecule affecting nearby cells, traveling short distances from its site of synthesis.
  • Endocrine Hormone
    Signaling molecule released into the bloodstream, capable of affecting distant target cells throughout the body.
  • Amino Acid Derivative
    Non-lipid hormone type, such as epinephrine, that binds to extracellular receptors and cannot cross membranes directly.
  • Protein Hormone
    Non-lipid hormone, like insulin, requiring extracellular receptor binding to initiate cellular signaling.
