|MadSci Network: Genetics|
As you may know, genes code for mRNA which is decoded by ribosomes to become amino acids chains using tRNAs to fish out the amino acids in the cytosol needed for the protein or polypeptide. So basically genes denote peptides and not lipids and sugars. But enzymes (enzyme = protein = peptides) catalyze the biochemical reactions needed to convert lipids or sugars into other metabolites. Therefore, genetic mutations or variants in the genes encoding these enzymes influence whether or not the correct non-proteins are produced by the cell. These derived metabolites (lipids, sugars) can have certain roles in the regulation process whether it be hormones or other biological aspect.
