Lecture 1-Biological molecules Flashcards
What different structures can carbon form?
Simple, Chain, Ring
Carbon can form 4 covalent bonds so it’s ………
Tetravalent
Why does carbon have unique stability + diversity?
,Because of its Valency + Low atomic weight
Cellular chemical reactions occur ,because of ……
A functional group transfer
What do functional groups have that dictate the function of compounds?
Specific CHEMICAL properties
Give an example of a CATECHOLAMINE
Adrenaline
Give an example of a RETINOIC ACID
Ethanoic acid
How are polymers formed?
By DEHYDRATION SYNTHESIS-removal of water
What does dehydration synthesis require?
ATP
How are polymers broken down?
By HYDROLYSIS-addition of water
What happens in hydrolysis?
Bonds BETWEEN reactants = broken + the energy released is STORED as ATP

2%
How much of a cell is DNA?
1%
How much of a cell is RNA?
6%
