Ek- Bs Lecture 1

Front 1

water

Back 1

solvent in which the chemical reactions of living cells take place

Front 2

hydrogen bond

Back 2

bonds that form between the oxygen on one water molecule to the hydrogens on another water molecule.

Front 3

hydrophobic

Back 3

"water hating"
causes molecules to aggregate

Front 4

hydrophilic

Back 4

molecules dissolve easily in water, negative charged ends are attracted to the positively charged hydrogens in water.

Front 5

Solvation

Back 5

when water molecules surround a hydrophilic molecule, and separate it from the group

Front 6

Name the two reactions in which water acts as a reactant or a product, this reaction occurs in cells very often. Involves water

Back 6

Hydrolysis, dehydration

Front 7

lipids:
solubility
name the 6 major groups

Back 7

low solubility in water, high solubility in non polar organic solvents

fatty acids, triacylglycerols, phospholipids, glycolipids, steroids, and terpenes

Front 8

name the 3 subgroup of lipids that are often called "fatty acids"

Back 8

triacylglyerolds
phospholipids,
glycolipids

Front 9

triglycerides (concept)

Back 9

constructed from a 3 carbon backbone, glycerol.
function to store energy
adipocytes (fat cells) are almost exclusively contain triglycerides in their cytoplasm

Front 10

phospholipids

Back 10

built from a glycerol backbone (3 carbons) however only 2 are attached to fatty acid groups.

one of the 3 carbon backbones is attached to a phosphate group. Great component of membranes.
Amphipathic, a polar phosphate group, and a nonpolar fatty acid group.
