Peptide transporters factor effects

S12, S42), but it is now known that albumin is not the governing factor, nor is it the most important factor to be considered in the accumulation of abnormal collections of body fluids (H8). Furthermore, it is apparent from the existence of relatively healthy adults with no albumin in the blood (B5, Bll) that the protein is not essential for life. Notwithstanding these lately appreciated facts, an important if not unique physiological role of albumin is its capacity to act as a vehicular substance for a wide variety of ions with different structures. In addition to its ability to bind and transport fatty acids, certain hormones, steroids, peptides, and amino acids, it can hold and effectively isolate the ions of many different substances that may be undesirable or dangerous to cellular life, e.g., phenols, phenolic acids, poisonous metals, bilirubin.
