Smooth Endoplasmic Reticulum (SER) synthesizes and processes lipids and carbohydrates, but what does this mean?

Hi there!
It means that:-
a) CARBOHYDRATES: e.g., an oligosaccharide complex is added to asparagine residues [an amino acid residue is the part left after formation of the peptide bond, yeah?] to form glycoproteins.
b) LIPIDS: sphingolipids & cholesterol [kinda lipids], etc [different types of lipids] are differentially distributed so that some lipids mix with particular other lipids BUT NOT with some others. This leads to selective protein channelling.
c) LIPIDS: Cholesterol is used as the starting point [like backbone] in the synthesis of steroids [hence the rich SER in cells that secrete steroid hormones e.g., in the ovary, the adrenal cortex.
Be safe!
