Enzymes that attach carbohydrates and lipids to proteins are called glycosyltransferases and lipid transferases, respectively.

Here's a breakdown:

* Glycosyltransferases catalyze the transfer of sugar moieties (monosaccharides or oligosaccharides) from donor molecules (like nucleotide sugars) to acceptor molecules, which are often proteins. This process is called glycosylation and results in the formation of glycoproteins.

* Lipid transferases catalyze the transfer of lipid molecules, such as fatty acids or phospholipids, from donor molecules to acceptor molecules, which are often proteins. This process is called lipidation and results in the formation of lipoproteins.

It's important to note that some enzymes may have dual activity, transferring both carbohydrates and lipids. However, the terms glycosyltransferase and lipid transferase are generally used to refer to enzymes with a specific activity.
