- 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.instructions: add the drawings to these given answers please. its urgent answers are given as follows A. The tetrahedral intermediate attacks the carbonyl carbon of the peptide bond, cleaving it and forming a new peptide bond with the nitrogen of aspartate. This process is repeated for each peptide bond in the substrate, resulting in the formation of the product and free enzyme. In this example, the product is a dipeptide and free enzyme. In addition to forming a tetrahedral intermediate, the catalytic mechanism of papain involves general acid-base catalysis through His57 in Asn152. The amino group in Asn152 deprotonates the hydroxyl side chain in Phe153, which is stabilized by hydrogen bonding. This deprotonation facilitates nucleophilic attack at the carbonyl carbon of the peptide bond in the substrate, resulting in a tetrahedral intermediate. His57 also protonates Asp102, stabilizing it as a general base to facilitate formation of the tetrahedral intermediate. The nucleophilic…Please answer yes or no and give a short explanation.
