In heme synthesis in mammalian cells: 1. uroporphyrin III is the immediate precursor of coproporhyrin III. 2. delta-aminolevulinic acid is formed by the condensation of succinyl CoA and valine. 3. ferric iron is inserted into protoporphyrin IX prior to attachment to the globin molecule.
If the linear function f is given, the linear equation of the graph of this function is obtained by defining the variable y to be the functional value f(x), that is, setting y = f(x) = ax + b and suppressing the functional notation in the middle.
Linear functions can always be written in the form f (x) =b + mx or f (x) =mx + b; theyâre equivalent where b is the initial or starting value of the function (when input, x = 0), and m is the constant rate of change of the function Many people like to write linear functions in the form.
