Flashcards in Lecture 4 Deck (18):
1

alcohol

An organic compound containing Hydroxyl groups

2

aldehyde

A compound that has a carbonyl group on the end of it's skeleton

3

amine

An organic compound with amino groups

4

amino group

Compound: Amine
Nitrogen atom attached to 2 H atoms and the skeleton
Acts as a base; ammonia can take H+ from the solution
Amino acids have amino and carboxyl groups

5

carbonyl group

Compound: Ketone (Carbonyl within skeleton)
Aldehyde (Carbonyl group at the end of the skeleton)
O atom joined to C skeleton with a double bond
Isomers with aldehydes vs. ketones have different properties.

6

carboxyl group

Compound: Carboxylic/Organic acid
C atom w/ double bond to O atom and single bond to Hydroxyl group
Acts as an acid. - O charges increase the dissociation of H+

7

carboxylic acid

A compound including a carboxyl group

8

enantiomer

Molecules that are mirror images of each other.
-L and R handed versions
-Usually one is biologically active and one is not

9

functional group

Components of organic mol'c's that are most commonly involved in chemical reactions.
-Each functional group behaves consistently across organic Mol'c
-6 functional groups:
-Hydroxyl
-Carbonyl
-Carboxyl
-Amino
-Sulfhydryl
-Phosphate
-All are hydrophilic

10

geometric isomer

Compounds with the same covalent bonds but differing structure arranged around double bonded C

11

hydrocarbon

Organic mol'c that ONLY consist of H and C atoms
major component of petroleum

12

hydroxyl group

Compound: Alcohol
H forms polar covalent bond w/ O and forms a polar covalent bond w/ the carbon skeleton

13

isomer

compounds w/ same molecular formula but different structures. Thus, different chemical properties.

14

ketone

Compound containing a Carbonyl group that is NOT on the end of the C skeleton
A carbonyl group @ end of skeleton is an aldehyde

15

phosphate group

Compound: Organic Phosphate
-Phosphorous bound to 4 O atoms
-Connects to C skeleton 2 w/ one O atom

16

structual isomer

Mol'c with same molecular formula but differ in covalent arrangement of electrons

17

sulfhydryl group

Compound: Thiol
S atom bonded to H and C skeleton
resembles Hydroxyl group in shape
Sulfhydryl groups stabilize structure of proteins

18

thiol

Organic compound containing Sulfhydryl group.
