Cards

Term

 

 

organic compounds

Definition
compounds conatining carbon. Most contain hydrogen atoms in addition to carbon atoms. An example of an organic compound would be methane (CH4).
Term

 

 

inorganic compounds

Definition

 

Any compund that does not contain carbon. For example sodium chloride (NaCl).

Term

 

 

amino acids

 

 

 

 

Definition

Organic molecules processing both carboxyl and amino acid groups.

Term

 

 

glucose

Definition

A monosaccharide that is a source for energy and metabolic intermediate. Products of photosynthesis and cellular respiration for both prokaryotes and eukaryotes.

Term

 

 

lactose

Definition

A disaccharide that consists of galactose and glucose found in milk.

Term

 

 

glycogen

Definition

A molecule that functions as an energy storage for animal cells.

Term

 

 

fructose

Definition
A simple monsaccharide found in many foods. For example syrup. Has a great effect on freezing points.
Term

 

 

sucrose

Definition
A disaccharide aka table sugar. Best known for human nutrition. Consists of two monosaccharides glucose and fructose.
Term

 

 

cellulose

Definition
A polysaccharide. A structural component for the cell wall of green plants.
Term

 

 

ribose

Definition

The sugar component of RNA.

Term

 

 

fatty acids

Definition

A long carbon chain carboxylic acid.

Term

 

 

monosaccharides

(three examples)

Definition
Glucose, fructose, and galctose.
Term

 

 

disaccharides

(three examples)

Definition
Sucrose, lactose, and maltose.
Term

 

 

polysaccharides

(three examples)

Definition
Cellulose, starch and glycogen.
Term

 

 

lipids

(three functions)

Definition
Energy storage, forming the membranes around our cells, hormones, and vitamins.
Term

 

 

carbohydrates

(compared to lipids in energy storage)

Definition
The C-H bonds found in carbohydrates store energy and the C-H bond is a weak bond, which means that it stores a lot of energy.
Term

 

 

lipids

(compared to carbohydrates in energy storage)

Definition
More reduced than carbohydrates, allowing them to store more energy.
Term
Outline the role of condensation and hydrolysis in the relationships between monosaccharides, disaccharides, and polysaccharides; between fatty acids, glycerol, and triglycerides; and between amino acids and polypeptides.
Definition
Monosaccharides condense to form disaccharides and polysaccharides; condensation means that two molecules become covalently bonded with loss of a water molecule. You get monosaccharides from disaccharaides and polysaccharides by hydrolysis, which is the breaking of a covalent bond by addition of a water molecule. Fatty acids and glycerol condense to form triglycerides (and the reverse). Amino acids condense to form polypeptides (and the reverse).
