👉 The Daniel fluid, also known as hyaluronan, is a complex glycosaminoglycan found in various tissues, particularly in the extracellular matrix of connective tissues. It plays a crucial role in maintaining tissue structure and elasticity by forming a gel-like network that helps retain water and facilitates cell signaling. This fluid is essential for tissue hydration, wound healing, and embryonic development. Additionally, it contributes to joint lubrication and the transmission of mechanical signals within tissues. Abnormalities in hyaluronan metabolism are linked to several diseases, including osteoarthritis and certain cancers, highlighting its importance in both normal physiology and pathology.
