hemerythrin
Hemerythrin is a specialized respiratory protein found in specific marine invertebrates. It serves a similar physiological role to hemoglobin in vertebrates or hemocyanin in mollusks, but it is chemically distinct because it binds oxygen without the use of a heme group.
As a technical term in biochemistry and zoology, it is used almost exclusively in scientific literature. It is an uncountable noun because it refers to a chemical substance or a class of proteins, meaning it does not typically take a plural form in standard scientific discourse.
Ý nghĩa
Ví dụ
Hemerythrin is a non-heme iron protein found in several marine invertebrates.
Does hemerythrin function similarly to hemoglobin in terms of oxygen transport?
