The phrase "also a precursor for" is correct and usable in written English.
It can be used when discussing something that serves as a forerunner or an early indicator of another thing.
Example: "The discovery of this ancient artifact is also a precursor for understanding the cultural practices of that civilization."
Alternatives: "also an indicator of" or "also a forerunner to".
Nietzsche is also a precursor for postmodernism in his genealogical analyses of fundamental concepts, especially what he takes to be the core concept of Western metaphysics, the "I".
In addition, (R -2-hydroxy-4-phenylbutyrate ((R -2-hydroxy-4-phenylbutyrateoR -2-hydroxy-4-phenylbutyrate synthesized thR -2-hydroxy-4-phenylbutyraten of 2-oxo-4-phenylbutyR -2-hydroxy-4-phenylbutyrateFiguR -HPB
L-Galactonic acid is also a precursor for L-ascorbic acid (vitamin C): L-galactono-1,4-lactone, which is formed from L-galactonic acid upon acidification, can be directly converted to L-ascorbic acid through a fermentative process (Onofri et al. [1997], Roland et al. [1986]) or through a chemical process (Csiba et al. [1993]).
However, homogentisate is also a precursor for the biosynthesis of pyomelanin, a brown pigment generated through the extracellular accumulation and polymerization of homogentisate.
In plants, ornithine serves also a precursor for polyamine and alkaloid biosynthesis [ 4].
G3P is also a precursor for serine biosynthesis, and thus the low levels of serine, and subsequently glycine, may be a consequence of decreased G3P.
Cognitive deficits could also be a precursor for dementia.
The product synthesized by these two enzymes in this cluster, 2,3-dihydroxybenzoate, is an iron binding compound, but also a precursor component for more complex siderophores, like acinetobactin.
Ornithine also acts as a precursor for proline biosynthesis, which is also a component of drought and salinity tolerance.
Alternatively, the expression pattern may also be relevant for other metabolic pathways since ornithine can also serve as a precursor for polyamine and alkaloid biosynthesis [ 4].
Overall, the present results indicate that capturing large-scale unsteady characteristics can provide more accurate predictions of recirculation dominated reacting flows and suggest that two-dimensional, time-averaged solutions represent a potentially useful engineering tool for problems of this nature while also serving as a precursor for full three-dimensional simulations.
