Biologically important

​although cells are made up 70%-0% water

the rest consits mostly of carbon based compounds

​all of organic molecule

proteins-> polypeptides
carbonhydrates -> polyascchardies
protein -> enzyme hexokinase
nucleus acids -> double-stranded DNA
carbohydrates -> sugar ,glucose
lipids -> phospholipids

Multiple Choice

proteins ->

• double-stranded

• sugar

• glucose

• enzyme hexokinase

Multiple Choice

nucleus acids

• molecules

• double-stranded DNA

• lipids

• proteins

Multiple Select

carbonhydrates

• proteins

• sugar

• daltons

• glucose

Multiple Choice

lipids ->

• polymers

• fatty acids

• phospholipids

• N/A

Macromolecules

a large organic molcule that ranges from about 1,000 daltons to about 2,000,000

Multiple Choice

what are the four main macromolcules?

• proteins , dna , lipids ,carbon

• organic ,polupeptides ,enzyme ,monomer

• carbonhydrates , lipids , nucleus acids ,proteins

• all of the above

polymer formation

linking two or more small molecules to form a large molecules with repeating structural units.

dehydration

reaction in which 2 molecules ecome covately bound to each other
through the loss of water
condensation of reaction

breakdown

chemical reactions breaking a larger molecule into its repeating structural units.

proteins

first place- are polymers of amino acids link together by covalent

-peptide bonds
- varitary processes
- Dna reptucation
- transporting molecules
-coatavling metabolic reactions
-providing structure

proteins

each have 3 dimensial from amino acids (monomers)

• green fluorscent protein

• lysozyme

• reserve transcriptase

• have many diverse and important functions In the cell

alpha ->carbon

a) hydrogen atom
b) carboxyl weak acid
c) amino group weak base
d) r-group
