What is an amino acid?
The monomers containting an amino group, a carboxyl group and a variable R group which makes up proteins
What is the symbol for an amino group?
NH2
What is the symbol for a carboxyl group?
COOH
What is an amulopectin?
A branched polysaccharide made up of alpha glucose monomers joined by a-1,6 glycosidic bonds that makes up starch with amylose.
What is amylose?
An unbranched polysaccharide made up of alpha glucose monomers joined by a-1,4 glycosidic bonds that makes up starch along with amylopectin.
What is an anion?
An ion with a negative charge.
What is benedict's test?
A biochemical test used to detect the presence of a reducing sugar in a solution and distinguish them between solutions of different reducing sugar concentrations.
What is biuret's test?
A biochemical test that prouduces a purple colour when it is added to a solution containing protein.
what is a cation?
An ion that is positively charged.
What is cellulose?
A linear polysacharide that is the main component of the celll wall in plants and is made up of many beta glucose molecules joined by b-1,4 glycosidic bonds.
What is chromatography?
A technique used to seperate different molecules in a solution by their different propeties.
What is cohesion?
A propety of water molecules that creates an attraction between them, causing them to stick together.
What is collagen?
A type of fibrous protein that provides strength to man different cell types and makes up connective tissues.
What is a condensation reaction?
A type of reaction that joins two molecules together with the formation of a chemical bond involving the elimination of a molecule of water.
What is a conjugated protein?
A protein with a prosthetic group bound to it.
What is elastin?
A type of fibrous protein that allows tissues and structures like blood vessels to stretch and return to their original shape.
What is a fibrous protein?
A class of long chain proteins that are generally insoluable in water and typically and structural roles
What is a golbular protein?
A class of spherical shaped proteins that are generally water soluable and typically have metabolic roles
what is glucose?
A hexose monosaccharide that is the main respiratory substrate in eukaryotes.
What is glycogen?
A highly branched polusaccharide that is used as the main energy storage molecule in animals and is made up of alpha glucose monomers joined by a-1,4 glycosidic bonds.
What is haemoglobin?
A type of conjugated golublar protein used to transport oxygen that is made up of four polypeptide chains each containing a haem prosthetic group.
what is a hexose monosaccharide ?
A simple sugar that contains 6 carbon atoms
What is a hydrogen bond?
A type of weak bond formed between an electropositive hydrogen and an electronegative atom like oxygen or nitrogen.
What is hydrolysis?
Breaking a chemical bond between two miolecules involving the use of a water molecule.

A globular protein hormone that is made in the pancreas in response to high glucose levels in the blood,
What is the iodine test?
A biochemical test that produces a blue/black color when added to a solution containing starch
What is keratin?
A type of fibrous protein that provides strength to hair and nails.
What is lactose?
A disaccharide made of a molecule glucose and galactose joinded by a glycosidic bond.
What is the lipid emulsion test?
A biochemical test that produces a cloudy emulsion when performed on lipids
what is maltose?
A disaccharide made of two molecules of glucose joined by a glycosidic bond
What is a monomer?
An individual unit that can be bonded to other identical monomers to make a polymer
What is a pentose monosaccharide?
A simple sugar with 5 carbon atoms
What is a phospholipid?
A type of amphipathic lipid made from a molecule of glycerol bonded to two fatty acid molecules and a phosphate group.
What is a polymer?
A molecule made from many repeating monomers joined together
What is a primary structure?
The individual sequence of amino acids in a protein.
What is a quarternary structure?
A structure only applicable to proteins with multiple polypeptide chains that describes the interactions of the different chains.
What is ribose?
A pentpose monosaccharide which composes the backbone of RNA
What is a saturated fatty acid?
A type of fatty acid molecule containing only single bonds between the carbon atoms.
What is a secondary structure?
The local interactions of the amino acids in the polypeptide chain.
