TRUE OR FALSE: Please answer each item. Hormones, such as testosterone, estradiol and progesterone are examples of steroidal lipids synthesized from cholesterol, which serve as precursor. Chain Shortening of monosaccharides can be done in the laboratory thru Kiliani-Fischer reaction. Glycerophospholipids are the most abundant lipids in cellular membranes and are also involved in metabolism and signaling In delta notation of fatty acid nomenclature, the numbering starts at the α-carbon from the carboxylic acid end. Chain elongation of monosaccharides can be done in the laboratory thru Ruff reaction.
