Cards

Term
Aldose
Definition
Based on the location of C=O, the functional group in the chain is an ALDEHYDE which gives you the name the aldose. the Ald=aldehyde and the ose=carb/sugar
Term
Amylopectin
Definition
Is a starch. Amylopectin refers to the branches on the structure.  It is an alpha (1-6) linkage at cross link. ( 2 alcohols reacting)
Term
Amylose
Definition

Is a starch. Amylose is the straight chain without the branches. it is a alpha (1-4) linkage 

(Most common type of starch)

Term
Anomers
Definition

Are stereoisomers that differ in the 3-D arrangment of groups at the anomeric carbon of an acetal, ketal, hemiacetal, or hemiketal group. You can use alpha or beta to identify anomers. Anomeric carbons are carbon #1. 

Alpha is down and beta is up!!

Term
Carbohydrates
Definition

Are polyhydroxy aldehydes or ketones or substances that yeild such compounds upon hydrolysis. 

General formula: Cx(H20)y

All have C=O and -OH functional groups. 

Term
Cellulose
Definition
The fiber in plants. The most abundant polysaccharide. It is Beta (1-4) linkage. Results in long fibers. 
Term
Chiral
Definition

 A Carbon has four attachments but are all different elements. 

 

 

 

Term
Dextrorotatory 
Definition

Rotate to right

Use + symbol

Usually D- isomers

Term
Levorotatory
Definition

Rotate to Left

Use - symbol

Usually L isomers

Term
Deoxyribose
Definition

It is a monosaccharides and are pentoses. They are used in the synthesis of DNA and RNA. 

 

slide 17-42

Term
Disaccharide
Definition

Is either and alpha or beta -OH group of cyclic monosaccharides that can form links with one another.

2 alcohols are dehydrated which knocks off H20 and makes ether linkage. Oxygen bridge is what links the sugars. 

Term
Fatty Acid
Definition
Is a long chain monocarboxylic acids used to produce waxes. Always an even number of carbon. Saturated: NO double bonds. Unsaturated: One or More double bonds( normally a CIS). The cis formation causes kinking in the chain. 
Term
Glycerolipids
Definition
Term
Glycogen
Definition

The energy storage for animals. Stored in liver and muscles as granules. Similar to amylopectin. 

Alpha (1-6) linkage at cross link. 

slide: 17-69. spherical structure

Body stores as carbs. 

Term
Glycosidic
Definition

 A bond type which is based on the position of the C-1 OH. 

Alpha : linkage between a C-1 alpha OH and alpha C-4 OH

Beta: linkage between a C-1 beta OH and alpha C-4 OH

Term
Hydrophilic
Definition
Water loving- The heads of lipids
Term
Hydrophobic
Definition
Water hating - tails of a lipid
Term
Ketose
Definition
It is a monosaccharide. Its functional group is a ketone
Term
Lactose
Definition

Is a milk sugar, dimer of beta D-Glucose. B-Dgalactose and Beta D-glucose link together forming the lactose. 

B(1-4) linkage, Beta disaccharide. 

slide: 17-53

Term
Lipid
