Carbohydrates can be attached to proteins to form glycoproteins. these modifications are quite common, with approximately 50% of the proteome consisting of glycoproteins. carbohydrates are linked to proteins through asn, thr, or ser residues by o-linked or n-linked glycosylation. two common forms of glycosylation include the addition of n-acetylglucosamine (glcnac) or n-acetylgalactosamine (galnac) which are glucose and galactose molecules modified at the 2’ position with the n-acetyl group.
what are the differences between o-linked and n-linked glycosylation?
of asn, thr, and ser, which residue(s) get o-linked and which are n-linked? explain.
draw o-linked glcnacylation and n-linked galnacylation (you can choose which residue you
depict the glycosylation with, sugars should be in haworth depiction).

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
