Human recombinant insulin can be easily produced in microbial systems, as it is a glycosylated protein. True False

False.<br /><br />Human insulin is NOT a glycosylated protein. This is precisely why it *can* be easily produced in microbial systems like bacteria. Bacteria lack the complex machinery for glycosylation (adding sugar chains to proteins) that eukaryotic cells like human cells possess. If insulin required glycosylation for its function, bacteria would not be able to produce a functional form.<br />
