Blood Red?

Ever wonder why Spock has green blood? Ask an avid Star Trek fan and they will tell you it’s because his Vulcan haemoglobin, the protein in blood cells that carries oxygen, is based on copper. Human haemoglobin (depicted here in a painting by Irving Geis) is however based on iron. Each haemoglobin molecule is constructed of four identical building blocks made of globin protein (purple) and heme (red). It is the heme group that gives our blood its distinctive red colour. Each heme contains an iron atom surrounded by a ring structure called porphyrin. When porphyrin is bound to iron carrying oxygen, it produces a red colour. While evolution paired up porphyrins with iron in humans, the same is not true for all creatures on earth. Molluscs, like Spock, also use copper giving their porphyrins a green hue.

PETA Poster Mockup

The second Project from Editorial Illustration where we were assigned to promote greyhound adoptions and bring attention to greyhound cruelty. A lot of research went into this piece, and most of it was incredibly depressing. If anyone has the chance to rescue a greyhound, I encourage you to do so.
