Phospholipid Molecules Study Guide

Improved Essays
A. Phospholipid molecule- A1: Phosphate Head (Charged, Hydrophilic), A2: Fatty Acid Tail (Non-charged, Hydrophobic).
B. Glycolipid.
C. Glycoprotein.
D. Carbohydrate chain of glycoprotein.
E. Cholesterol.
F. Protein.
G. Protein Channel (present as a pore within the membrane).
H. And I. Phospholipid Bilayer (about 7nm).

(b) Explain how the properties of A and C cause them to be arranged in Plasma Membrane.

• Structure A is the phospholipid molecule which consists of a phosphate head and fatty acid tails. The phosphate head is charged whereas the fatty acid tails are uncharged. It’s because the head is charged is what makes it hydrophilic (water-loving). And similarly the fatty acid tails are uncharged making them hydrophobic (water-repelling).

    Experiment 2: The Size of Molecules & Avogadro’s Number Name: Julia Bland Lab Section: Tuesday A.M. (11:30) TA’s Name: Yuogi Date: October 15th Course: CHEM 1001 Abstract: Avogadro’s number is one of the vital constants in the chemistry world, used in a multitude of experimental and theoretical calculations. This lab endeavours to experimentally measure Avogadro’s number by adding drops of stearic acid into a known area of distilled water, and using this data, calculate the molecules in the monolayer. The experimental value of Avogadro’s number using stearic acid was found to be 8.689 x 1022 with a 0.144 value of range (0.1-10) being within the literature value order of magnitude. Through this experiment an understanding of the complex…

    The actual membrane is created up of phospholipids which naturally form a bilayer, these phospholipids have a head that are hydrophilic and two fatty acid tails that are hydrophobic, and this allows water molecules to pass between the phospholipid molecules by osmosis and allowed self-orientating properties. It’s more than just a passive envelope; it is a dynamic structure that is actively involved in cellular activities such as cell signalling, cell-cell recognition and of course hydration. Another process important in cells is active and passive transport, which is the biological process that moves oxygen, water and nutrients into cells and remove its waste products. The difference between them is that active transport requires chemical energy as it is the movement of those chemicals from areas of lower concentration to areas of higher concentration while on the other hand passive transport requires no energy as it is the transportation of biochemical from areas of high concentration to low concentrations. In the report, active transport is the one which will be demonstrated as it is the transportation of low-to-high concentration.…

    Background: The cell membrane surrounds all cells and controls what comes in and what goes out of the cell. It is selectively permeable (it permits certain things to enter and prevents other things from coming in). There is a phospholipid bilayer in which the hydrophobic tails point inward and the hydrophilic heads point outwards. Inside this plasma membrane there is usually an integral protein, cholesterols, a protein channel (for substances that can’t enter through the phospholipid bilayer), a peripheral protein, and a transport protein to pump molecules.…
