Post Translational Modification?
Answer:
I have one fundamental problem near your question: Neither lipid or carbohydrate molecules are translated. Infact, the merely type of molecules that ARE translated, are the proteins, which originates from mRNA through (as stated) translation by the ribosome, tRNA etc. After translation, these proteins (also call polypeptides) can undergo modifications which include phosphorylation, acetylation, glycosilation, etc etc.
Simple carbohydrates and lipids are ingested near food and metabolised, More complex molecules are synthesized from thse simple molecules. For example, all carbohydrates share a common formula of approximately CnH2nOn; glucose is C6H12O6. Monosaccharides may be chemically bonded together to form disaccharides such as sucrose and longer polysaccharides such as starch and cellulose.
I agree with lovely green eyes that this is a really doomed to failure question. What I construe the question is trying to carry at are descriptions of lipoproteins and glycoproteins. Check out the wonders of the endoplasmic reticulum and the Golgi apparatus!
