Air‐dired kangaroo tail tendon (KTT) is a protein sample similar to collagen and has been investigated by small‐angle x‐ray scattering treating it as a densely packed colloidal system which belongs to a general micelle system. Pore analysis of the substance yields a specific inner surface of 0.6282 × 10−5 Å−1, a range of inhomogeneity of 69.11 Å, a length of coherence of 248.2 Å, and air‐fraction percentage of 0.011. A Kratky camera of the latest design has been used for experimental measurements. As the logĨ vs. logX curve gives a slope of −3, KTT belongs to a densely packed two‐phase system. Here the theory of small‐angle scattering by densely packed systems as developed by Porod has been applied to find different physical parameters of KTT.
