Very detailed lecture summaries, including Guest lectures. With my summary I had scored a 8.5 on the test. I did not have enough time to summarize lecture 2 and 10. However, I included a written summary to help you understand this lecture. Guest lecture 2 and 4 are also included by a written summary. Lecture 1, 7 and Guest lecture 3 are included with a detailed summary and written back up notes, since these were challanging lectures. 1 Practice exam is included with answers.

This document consists of a summary of the course Protein Science, corresponding to the Master Biomolecular Science.

Compartmentalization correct answers The segregation of functions into different compartments; in the cell, increases the efficiency of chemical reactions Lipid correct answers Any organic molecule that is poorly soluble or virtually insoluble in water but is soluble in nonpolar organic solvents; make up the membranes of cells Membrane correct answers Made of either phospholipids or phospholipids and sterols; often bilayers with polar head group facing outside from hydrophobic tails Per...

FOOD ANALYSIS EXAM 2 2024 WITH 100% ACCURATE SOLUTIONS Itemize the procedures that may be required to prepare a food sample for accurate fat determination by a solvent extraction method (e.g., Soxhlet method). Explain why each of these procedures may be necessary. (3) - correct answer Predrying sample - Fats cannot be efficiently extracted from moist foods with ethyl ether; ether saturated with water is inefficient for fat extractions; dried samples are easier to grind. Particle size r...
