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.
Graph sample of linear equations. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable.Linear equations can have one or more variables. Linear equations occur abundantly in most subareas of mathematics and especially in applied mathematics. linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable.
