Water To Proteins Flashcards
One use of phosphate ions
DNA,RNA,ATP phospholipids
Properties that allow plants to do transpiration
Adhesion and cohesion
Structure of water that gives it unique properties
Dipolar
And forms hydrogen bonds with other molecules
What property of water means enzymes are kept at their optimum
High specific heat capacity
Give one use of iron ions
haemoglobin
State the general structural formula of monosaccharides.
(CH2O)n
What monosaccharides are found in lactose?
Galactose and glucose.
– Describe how maltose is digested
Hydrolysed, breaks 1-4glycosidic bond, into glucose, by maltase, water needed/added
Explain why the structure of cellulose makes it good at its job
each beta glucose inverted 180 degrees makes it straight- so can be in layers.
H bonds between layers forms fibrils and microfibrils These give it strength.
Describe similarities between the structure of amylopectin and glycogen
alpha glucose, 1-4 glycosidic bonds, and 1-6 glycosidic bonds, both branched
Describe the main difference in structure between amylopectin and glycogen
glycogen has more 1-6 glycosidic bonds = more branched
Describe how a triglyceride would be made from its components?
Describe how a triglyceride would be made from its components?
– Describe the differences between a triglyceride and a phospholipid
phospholipid one of fatty acids has been replace with a phosphate ion, phospholipid has a hydrophilic (Charged/polar head) and hydrophobic tails
Describe the primary structure of a protei
sequence of amino acids bonded by peptide bonds
Describe the tertiary structure of a protein
3d structure further folding, – disulphide, ionic bonds,
hydrophobic interactions
What bonds form to turn a primary protein into a secondary protein?
Hydrogen
Give an example of a quaternary protein
Haemoglobin
