In healthy subjects, the level of the oxidized form is about 35%, but it rises up to 70% after oxidative insults or in patients with kidney diseases. Oxidized albumin is therefore considered a short\u2010term biomarker of oxidative stress as its level may increase or decrease under appropriate redox inputs in discrete temporal spans. This paper defines, for the first time, the kinetic properties of reduced and oxidized Cys\n                    <jats:sub>34<\/jats:sub>\n                    of HSA in their reactions with natural disulfides and thiols. Kinetic constants support the evidence that the Cys\n                    <jats:sub>34<\/jats:sub>\n                    redox oscillations observed\n                    <jats:italic>in vivo<\/jats:italic>\n                    are mainly due to the interaction with cysteine and cystine without the involvement of any enzymatic support. This study gives also a plausible explanation for the absence of involvement of the 17 disulfides naturally present in HSA in these redox transitions. This inert behavior toward cysteine is marginally due to solvent accessibility or flexibility factors of these bonds but mainly to their strong thermodynamic stability, which is caused essentially by a proximity effect. A similar mechanism is likely at play in the many proteins that maintain disulfide bridges in a reducing medium like the cytosol.\n                  <\/jats:p>","DOI":"10.1111\/febs.14609","type":"journal-article","created":{"date-parts":[[2018,7,20]],"date-time":"2018-07-20T05:21:50Z","timestamp":1532064110000},"page":"3225-3237","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":85,"title":["Thiol disulfide exchange reactions in human serum albumin: the apparent paradox of the redox transitions of Cys\n                    <sub>34<\/sub>"],"prefix":"10.1111","volume":"285","author":[{"given":"Alessio","family":"Bocedi","sequence":"first","affiliation":[{"name":"Department of Chemical Sciences and Technologies University of Rome Tor Vergata Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giada","family":"Cattani","sequence":"additional","affiliation":[{"name":"Department of Chemical Sciences and Technologies University of Rome Tor Vergata Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenzo","family":"Stella","sequence":"additional","affiliation":[{"name":"Department of Chemical Sciences and Technologies University of Rome Tor Vergata Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renato","family":"Massoud","sequence":"additional","affiliation":[{"name":"Department of Experimental Medicine and Surgery University of Rome Tor Vergata Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giorgio","family":"Ricci","sequence":"additional","affiliation":[{"name":"Department of Chemical Sciences and Technologies University of Rome Tor Vergata Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,8,2]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.freeradbiomed.2013.05.050"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-012552110-9\/50004-0"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41419-018-0289-3"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.xphs.2017.03.002"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1089\/ars.2005.7.951"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1159\/000101986"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1523-1755.2004.00969.x"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0085216"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbrc.2005.07.035"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1755.2001.00807.x"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0076-6879(10)74011-8"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.3892\/etm.2017.4268"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/febs.13909"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-8981(00)00369-7"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1744-9987.2010.00841.x"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/tx100413v"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M115.672816"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.abb.2012.03.011"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/0076-6879(86)28077-5"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1021\/bi027434m"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jchromb.2009.03.035"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1021\/bi701520y"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-018-19610-9"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpcb.5b00144"},{"key":"e_1_2_9_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/0141-8130(93)90043-L"},{"key":"e_1_2_9_27_1","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/gkh381"},{"key":"e_1_2_9_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.freeradbiomed.2017.04.021"},{"key":"e_1_2_9_29_1","first-page":"83","volume-title":"Biotechnology of Plasma Proteins","author":"Lundbland RL","year":"2013"},{"key":"e_1_2_9_30_1","doi-asserted-by":"publisher","DOI":"10.1093\/clinchem\/41.3.361"},{"key":"e_1_2_9_31_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpendo.1996.270.2.E209"},{"key":"e_1_2_9_32_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1755.2002.00151.x"},{"key":"e_1_2_9_33_1","doi-asserted-by":"publisher","DOI":"10.1016\/0076-6879(86)31036-X"},{"key":"e_1_2_9_34_1","first-page":"459","volume-title":"IUPAC.
