Draw a fat with 12-3 fat with a 12 carbon chain, one saturated 14 carbon chain and one 2-3 chain 18 carbons long.

A starved subject is fed with radio labeled protein (with NT5 and C14). Breath, blood, urine and liver samples are analyzed for chemical composition. List the names of the different compounds that will be labeled with radioactive carbon or nitrogen in the four different samples (state which compounds will be labeled with N15 and which will be labeled with C'14). Sample 1: Liver Sample 2: Breath Sample 3: Blood Sample 4: Urine

Which bond in maltose will be hydrolysed by starch? OH DE HO" B '"OH ОН HO Select one: O B O D O A

Misty Copeland is taking a snack break from her 8-hour rehearsal day and she wants to aid her muscles with recovery by eating a protein-rich snack. Part 1: What is the name of the monomer used to synthesize the protein and what is the name of the covalent bond that holds these monomers together? Part 2: The cells lining the inside of Misty Copeland's stomach need to produce and secrete enzymes like pepsin that will help breakdown the protein-rich snack she just ate. Using your knowledge of the endomembrane system (1) describe the pathway taken by the newly synthesized enzymes that will be secreted by her stomach cells? Include the terms cis-facing and trans-facing in your answer. (2) Include the type of cellular transport required for the enzyme to leave the cell. Part 3: The pH of Misty's stomach is low. For enzymes not used to this environment, which levels of protein structure will be affected? Briefly explain why the level(s) of structure you selected are being impacted. Part 4: If…

Give three physiological functions of fats and oils.

During hydrogenation, cis double bonds are converted to trans double bonds.  In the lab, we compare three fats, each of which has fatty acid chains that are exactly the same length (number of carbons) and observe the following: Fat 1 contains only saturated fatty acids 16 carbons long, and has a melting point of 65 degrees C. Fat 2 contains only cis unsaturated fatty acids 16 carbons long, and has a melting point of 35 degrees C. Fat 3 contains only trans fatty acids 16 carbons long, and has a melting point of 65 degrees C. Both Fat 2 and Fat 3 contain fatty acids with a single double bond; fat 1 has no double bonds.  Why do Fat 3 and Fat 1 have more similar melting points than Fat 3 and Fat 2? Group of answer choices The number of hydrogen atoms in the fatty acids of fats 1 & 3 is higher, and having more hydrogen atoms raises the melting point of the fat. The fatty acids in fats 1 & 3 have a linear shape, so they pack tightly together and have lots of hydrophobic…
