Lecture 3 Flashcards
Functional Groups
Groups of atoms that replace a H in an organic structure
Aldehydes and Ketones have what?
Carbonyl functional group C=O
hydrolysis
Reactant + H2O product
adds water to break down
condensation
Reactant H2O + product
condenses and removes water
Esters
prepared by reacting carboxylic acids with alcohols
Ex. ethyl acetate is prepared by the condensation reaction of acetic acid with ethanol
Amides
formed by the reaction of carboxylic acids with an amine
Amines
a basic functional group
containing a nitrogen atom bonded in a hydrocarbon framework
Biochemistry
the study of chemistry that takes place in the living cell
The most important types of biochemical compounds
Carbohydrates – Cx(H2O)y
Lipids: the oil soluble part of a cell- includes triglycerides aka fats
Amino acids and Proteins
Vitamins
Hormones
Carbohydrates
contain carbon, hydrogen, and oxygen and have the general formula
Types of Carbohydrates
Monosaccharides = simplest carbohydrates or sugars
(Glucose)
Disaccharides = 2 monosaccharides
Polysaccharides = many monosaccharides, polymers of sugar molecules
Fats
lipids derived from animals
They contain mostly saturated fatty acids that have been condensed (esters) with glycerol
Most are solid at room temperature
Oils
lipids derived from plants
They contain a larger proportion of unsaturated fatty acids condensed (esters) with glycerol
Most are liquid at room temperature
Saturated fatty acids
contain no C=C double bonds
Monounsaturated fatty acids
contain one C=C double bond
Polyunsaturated fatty acids
contain more than one C=C double bond
