Lymph, while containing many proteins, notably lacks certain types. The absence of specific proteins in lymph isn't a simple yes/no answer; it depends on the specific protein and the individual's health status. However, based on available research, some notable absences include:
-
Large plasma proteins: While lymph does contain proteins, these are generally smaller than those found in plasma. The reference material explicitly states that "Large plasma proteins" are absent in lymph.
-
Proteins indicative of specific pathologies: The absence of certain proteins can indicate a disease state. For instance, the absence of an M-spike (monoclonal gammopathy) in serum protein electrophoresis doesn't rule out multiple myeloma. This shows how the absence of specific proteins can be clinically significant. The absence of certain proteins in lymph may also be a sign of impaired lymphatic function or certain diseases.
While many proteins are present in lymph, the absence of specific types, especially large plasma proteins, is a key differentiating factor between lymph and blood plasma. The context of protein absence also requires consideration of health conditions.
