Ch.1-3 Organic Chemisty Basics and Carbohydrates Flashcards
How many and what types of bonds can carbon form
4 covalent bonds
Can be single double or triple
How many valence electrons does carbon have
4
Describe the carbon chains
Straight, branched, or rings
Vary in length, number, location of double bonds, and the presence of other elements
Carbon can form isomers
What does this mean and name a few
Same chemical formula - different structure
Glucose fructose and galactose
Name the functional groups
Hydroxyl Carbonyl Carboxyl Amino Sulfhydral Phosphate Methyl
Properties and formula of hydroxyl
Polar
Water soluble
Alcohol
C-OH
Properties and formula of carbonyl
Polar
Water soluble
C double bond O
What two forms can a carbonyl be
Ketone
Aldehyde
What is the ketone
When carbon double bond oxygen is in the middle of the structure
What is aldehyde
When carbon double bond oxygen is on the end of the structure
What are the properties and formula for carboxyl
Polar
Water soluble
Acidic
COOH
What are the properties and formula for amino

Water soluble
Form weak bonds
N bonded to H
What are the properties and formula for sulfhydral
what it forms and where found
Forms disulfide bridge
Found in stabilizing protein shape
SH
What are the properties and formula for Phosphate
Polar
water soluble
acidic
P double bond O
Properties and formula for methyl
Where is it normally
Nonpolar
Not water soluble
On lipids
C with 3 H
Usually at end of carbon chain
What are carbohydrates
Polymers of simple sugars
How are carbohydrates classified
According to number of sugars
Describe the sugars
( # of carbons )
( structure )
3-7 carbons
OH attached to each carbon except one
Aldehydes or Ketones
Does glucose contain an aldehyde or ketone
Answer for galactose and fructose also
Glucose - aldehyde
Fructose - keytone
Galactose - aldehyde
