Macromolecules Lect. 4 Flashcards
Salts
Any ionic compound that does not contain H+ cation or OH anion. produced from the reaction between a acid and base. Cation base and anion acid
Carbohydrates
starches, sugars: organic molecules that always have a carbon, hydrogen, oxygen, polar
Monosacchrides
simple building sugar blocks , contain C, H, O and simplest form of carbohydrates
Deoxyribose (DNA) and ribose (RNA) are types of these
The joining of two monosacchrides caused by dehydration sythesis.
Isomerism
chemical compound with the same formual but different structure.
Disaccharide
Two joined monosaccharide’s formed through dehydration synthesis.
Glycosidic Bonds
Between indepedent glucose bonds
Polysaccharides
long chains of monosaccharides:
1. Starches (Alpha) easily digested and have alpha glycosidic linkages. Increase gut motility, insoluble fibers. Enzymes are better at breaking these.
2. Cellulose (fiber) hard to digest (soluble fiber)
3. Glycogen (easy to digest) stored in liver, muscle and has beta glycosidic linkages made. Stored form of glucose. Ennzymes cannot break.
Hyperglyecemia
High blood glucose/sugar, if insluin cannot prepare cells for glucose
Type 1 Insulin Dependent Diabetes Mellitus
Destroys Beta cells so there is no insluin
Type 2: Non insulin dependent
Cell resistance ; hyperseceretion of Insulin led to cells stop taking in glucose.
Lipids
Nonplar, insoluble, and hyrophobic
must have a transport mechanisum as they cannot dissolve.
6 groups:
fatty acids, eiconsanoid, glycerides, steriods, phospolipids, glycolipids
Fatty Acids
Long hydrocarbons with carboxylic acid group at one end which is hydrophillic. Mainly nonpolar: Allow them to attach to building blocks. Only the hydrophillic end likes water so longer tails are less souble. Building blocks of fats
Saturated vs Unsaturated vs trans fats
Saturated are each carbon atom is attached, no double bonds only single
Unsaturated there is at least 1 double bond
Transfats have hydrogen on opposite sides and a trans double bond
econsanoids
non-polar, lipids which are derived from arachidonic acid (cannot be sythesized) two types:
Leukotrienes: white blood cells released with prostaglandins, inflammatory response
Prostaglandin: local hormone and causes regional inflammation due to damage
Glycerides
A result of dehydration synthesis between glycerol and fatty acids chains. One of three dehydration sythesis reactions result in systhesis of triglycerides.
Triglycerides
The largest (fat) energy stored in the body and have three main functions. Contains a glycerol and 3 fatty acid chains and made from 2 dehydration reactions.
- energy source
-insulation
-Protection
Type of glycerides
Fats (ketosis)
(glucose replacement) Result from excess breakdown of fats which create ketones in the liver if no glycogen is available. Leads to ketoacidosis High amounts of hydronium.
