What is the function of carbohydrates?
Quick energy
The building blocks of proteins.
What are amino acid?
What is the function of fats?
stored energy - 2x as much energy as proteins or carbs
What is the function of an enzyme?
to speed up chemical reactions
What color would a positive iodine turn and what type of carbohydrate would test positive?
Blue black or purple, polysaccharide
What are the "building blocks" of carbohydrates?
What are monosaccharides?
What are the "building blocks" of fats?
1 glycerol and 3 fatty acids
What kind of molecules is an enzyme - a protein a fat or a carbohydrate?
protein
Why did the food coloring act different in the different milks?
Because they had different amounts of fats
Which is the largest molecule, therefore having the most energy ( more bonds)
Sucrose
Glucose
Starch
Starch - polysaccharide
as the bonds break, energy is released
How many different amino acids are there?
20
What is the name of the process of building a larger molecule and losing a water called?
Dehydration synthesis
When a reaction is heated up a little, what will happen?
Greater reaction because molecules move faster, colliding more
5 drops and heat - turns orange. Monosaccharide.
In our lab, what results would you get with sucrose for the benedict's test and the iodine test?
There would be no change with either b/c sucrose is a disaccharide
What are the functions of proteins?
build and repair muscle, enzymes and hormones
hair and nails. At least 2
Which are healthy and which are unhealthy?
Trans Fats
Unsaturated fats
Saturated fats
Trans fats and saturated fats are unhealthy
Unsaturated fats are healthy
If a reaction is heated up VERY high, what will happen and why?
The reaction will stop b/c the heat will kill the enzyme
In the potato lab, what was the substrate and what was the name of the enzyme?
The substrate was hydrogen peroxide and the enzyme was catalase - in the potato
What is the formula for glucose?
What is C6H12O6?
What 4 elements make up proteins?
carbon
hydrogen
oxygen
nitrogen
What type of fat is this?
Polyunsaturated fat
b/c it has many double bonds
Label this reaction
A substrate
B active site
C enzyme
D products
Why did the ground up potato have a bigger reaction?
More surface area releases more enzymes, bigger reaction
