Many Defined Growth Media That Support Microbial Growth Lack Malonate

question 7

True/False

Many defined growth media that support microbial growth lack malonate, which is an important precursor for biosynthesis of lipid membranes. Based on this, we can infer cells also must have a metabolic pathway to generate malonate from other compounds.
