Lipids

The heterogeneous classes of organic compounds that are not water-soluble but are dissolved in organic solvents that are non-polar in nature are termed lipids. They are a long chain of fatty acids and esters of alcohols. Lipids are generally seen in seve…

Glycerophospholipid

Glycerophospholipid is the most abundantly occuring phospholipids found in the biological membranes. Lipids include a group of organic compounds like fats, hormones, oils, waxes, vitamins etc. They are non-polar molecules and are insoluble in water. Lipi…

Structure Of Camphor

A terpene with the molecular formula of C10H16O is a waxy, white color solid known as camphor. It is flammable. It also possesses a very pungent taste and a strong odor. There are various sources for extracting camphor from natural products such as the …

Glycolipid In Organic Chemistry

Glycolipids are lipids that are an important class of organic compounds in chemistry that have simple to complex applications. They contain carbohydrates, fatty acids, sphingolipids or a glycerol group. In other words, they are the modifications of lipid…

Diterpenoid

The terpenoid class includes diterpenoids, which are chemical compounds with 20 carbon atoms. They are made up of four isoprene units and are derived from geranylgeraniol, a C20 precursor. They have a C20H32 basic structure. These characteristics disting…

Textbook Question

Chapter 19, Problem 19.105EP

Indicate whether each of the following statements about a lipid bilayer is true or false.

a. The outside surface positions in a lipid bilayer are occupied by hydrophobic entities.
b. The interaction between the fluid inside a cell and the surface of a lipid bilayer is primarily an interaction between polar entities.
c. The outside surface positions in a lipid bilayer are occupied by the nonpolar tails of phospholipids and glycolipids.
d. The interactions between adjacent lipids in a lipid bilayer usually involve covalent bonding.

Name: b) Cellular membranes are generally found in environments that contain lots of water. Draw a diagram of what the phospholipid bilayer of a plasma membrane would look like if it were placed in a hydrophobic environment. (**Note that you only have to draw the phospholipid bilayer, you don't have to draw the other major components again as you did in part a) c) What part or parts of a cellular membrane play(s) a role in determining the fluidity of the membrane? 8) Indicate which of the five major types of membrane protein (adhesion, enzymatic, recogniti receptor, and transport) is most likely to be involved in each of the situations described below: a) An oncologist wants to study the cells from a certain tumour that has been surgically remov from a patient. However, she must first treat the tumour with a solution affects a membrane protein on the tumour cells. Because of the effect of the solution on the membrane protein, the tumour tissue falls apart into individual cells. Type of…
