• Benedict's test . Answer: Which food test is heated in a water bath?
• Sucrose . Answer: Which disaccharide is not a reducing sugar?
• Test for non-reducing sugars . Answer: Add acid. Neutralise. Add
Benedicts. Heat.
• Hydrolysis . Answer: Reaction performed by dilute HCl in the non
reducing sugar test.
• Glucose + fructose . Answer: During the non-reducing sugar test what
is sucrose hydrolysed into?
• Alpha . Answer: Which type of glucose makes up starch?
• amylose and amylopectin . Answer: Names of two types of starch
• Amylose . Answer: Coiled, compact form of starch. Stored easily.
,• Amylopectin . Answer: Branched form of starch. More easily
hydrolysed.
• surface area . Answer: Branched carbohydrates have a higher _____
for enzymes to work on.
• Glycogen . Answer: Carbohydrate store in animals
• branched . Answer: Glycogen is....
• metabolic rate . Answer: Glycogen is more branched than amylopectin
because animals have a higher _____________
• osmotically inactive. . Answer: Starch is insoluble and therefore ....
• Beta . Answer: What type of glucose is cellulose made from?
• Alpha and beta glucose . Answer: H and OH swapped on Carbon 1.
• Fibrils . Answer: Cellulose forms long chains called...
• H bonds . Answer: Cellulose molecules are crosslinked by
• strength . Answer: Cross linking of cellulose molecules gives them...
, • Triglycerides . Answer: _______ are a good source of energy because
they have a high ratio of energy-storing carbon-hydrogen bonds
• what are the roles of lipids? . Answer: 1. source of energy
2. waterproofing
3. insulation
4. protection
• how does the structure of phospholipids relate to their properties? .
Answer: 1. polar, therefore will position itself to form a bilayer
2. the structure allows them to form glycolipids by combining with
carbohydrates within the cell-surface membrane. these are important in
cell recognition.
• draw the structure of an amino acid . Answer:
• draw how a dipeptide forms . Answer:
• what is meant by 'primary sequence' of a protein . Answer: The unique
sequence of amino acids that make up a protein or polypeptide chain
• what is meant by 'secondary sequence' of a protein . Answer: The way
in which the primary structure of a polypeptide chain folds e.g. alpha
helix or beta pleated sheets. shape is held by H bonds.
