So I was at Wikpedia reading about Goliath (because who in hell was Goliath? nobody knows) when I read: “According to the Jerusalem Talmud, Goliath was born by polyspermy,

From Ask a Scientist: “Serum and plasma both come from the liquid portion of the blood that remains once the cells are removed, but that’s where the similarities end.
Transferrins
Transferrins are not limited to only binding to iron but also to different metal ions.
Hephaestin, first identified in 1999 is homologous with ceruloplasmin
Named after Hephaestus, the Greek god of metal working

We could find no reports on green plasma in the past 40 yr in either the surgical or the anesthesia literature, which perhaps explains the lack of knowledge on the part of today’
It Ain’t Easy Being Green
Is this why they have gone off the rails with the beta carotene and related things? Thoughts for another day. A search for “green plasma” at pubmed turns up 130 article

ABSTRACT: Recently we have noticed that many plasmas in female blood donors have been extremely green. A green plasma in a unit of blood usually suggests the presence of a gram-neg

ABSTRACT: Of blood donations reaching the Leeds Regional Blood Transfusion Laboratory about 1% have green plasma. Most of these come from women taking oral contraceptives, who cons
Ceruloplasmin carries more than 95% of the total copper in healthy human plasma and in addition plays a role in iron metabolism. It was first described in 1948.
Ceruloplasmin (or caeruloplasmin) is a ferroxidase enzyme that in humans is encoded by the CP gene. Ceruloplasmin is the major copper-carrying protein in the blood, and in
