And because lipids, or because membranes consist of lipids, by adding a lipid component onto our protein, we're increasing that protein's affinity to the membrane. So this process is known as lipidation. So we saw that phosphorylation, methylation glycosylation, proteollysis, and acetylation and lipidation are six different processes that are known as posttranslational modification. So these are the ways by which our polypeptides are modified following the process of translation. Now, there are actually even more processes than we discussed in this lecture, and we'll discuss those in more detail when we get into biochemistry. Now, another type of process that takes place following our translation is the folding of the protein.
