Document Summary
Second double bond between 12 and 13th carbon. C16:1 cis- 9 = c16:1 (n-7) = c16:1 ( -7) = c16:1 omega means count from other end. C16:2 cis,cis- 9,12 = c16:2 (n-4) = c16:2 ( -4) = c16:2. Hdl high density lipoprotein collects cholesterol from tissue (ldl is opposite) Different types base on group attached to phosphate. Sphingolipids used in membranes- can have fatty acid attached to nh3 group. Other lipids includes retinol, eicosanoids, prostaglandin etc. Ion channels targeted by toxins (poisonous animals) Most common trans-membrane domain is helix (20 aa hydrophobic) (cid:894)(cid:272)a(cid:374) use -sheets) Monolayer-associated in one layer of protein comes out on same side (into cell then membrane back into cell) Monosaccharaides (ch2o)n n is between 3 and 7. Named carbon #, -ose triose, tetrose, pentose etc. Oh on bottom is on right, =o is the top. Sugar - anomeric oh opposite side to c6. Sugar anomeric oh same side as c6.
