    δ-D,L-Hydroxylysine Analysis Service

      D- and L-δ-Hydroxylysine (D- and L-δ-Hyl) are crucial components of collagen and its metabolism, extensively found in connective tissues. These stereoisomers play significant roles in maintaining the stability and structural integrity of collagen. Changes in D- and L-δ-Hyl levels can be associated with various conditions, such as osteoporosis, arthritis, and skin disorders. Accurate measurement of D- and L-δ-Hyl concentrations is vital for understanding their roles in health and disease, providing a basis for diagnosing and treating related conditions.
