Enantiomers etc... Flashcards
(19 cards)
What is the main feature of enantiomers?
They have the same physical and chemical properties but different physiological properties and so they act with our body in a different way
What are the two main reactions that happen in macromolecules?
What condensation does do?
What hydrolysis does?
1: condensations
2: hydrolisis
What does condensation need?
It needs energy, endergonic(endometriosi)
Hydrolisis? Energy?
It realises energy exergonic
What are disaccharides?
Two monosaccharides linked together trough a condensation reaction(polisaccarides formed by two)
Where does maltose come from?
Comes from the hydrolisis starch(a glucose, a glucose),
What is the bond between two monosaccharides called?
Glycosidic Bond
For what it is used Hawarth Projection?
Used for the ring structure
What happens for a form and b form in water?
They are in equilibrium(60%-40%)
What are the two main types of classification of carbohydrates?
1: ENDoses(at the end chain KEToses(in the middle of the chain)
2: according to the number of C Chains
Explain what happens to the linear structure in water?
The structure is not stable, it tends to close on itself closing a ring
2 main features of polysaccharides:
CglSS
1: storage(they store energy, in plants: starch, in animals: glycogen
2: structural(they build in plants, cellulose in animals: chitin)
What is starch. Definition
Starch is a polymer of a glucose. Mixture of two different monosaccharides, analyse and amilopeptine,
Can Animals Break down Starch?
Yes they can, trough a particular enzyme: anylases
What is glycogen?
Similar to amylopectine but it is more densely branched. It was our body break down to gather energy
What is cellulose?
most abundant element expecially in cell walls of plants, it provides strenght and Support (and skeleton)
- polimer of B-glucose linear, unbranched
How Sucrose is composed?
A glucose+B glucose
How lactose is composed?
B glucose+B glucose
