What regions are poplar nonpolar in a membrane?
1) the phosphates are Polar, water lovin, hydro philic regions that
face the outside.
2) Nonpolar, hydro phobic carbon chain regions face the inside.
Explain glycolipids structure.
glycolipids have 3 carbon backbone with
2 Carbon chains attached by an ester
group. THe third carbon has a
carbohydrate
What do steroids look like?
Slightly amphipathic 4 ring structures
,lipids are insoluble. So how do they move through the blood?
They are usually carried by lipoproteins, like HDL or LDL.
What are the major classes of lipoproteins?
1) Chylomicrons which are the largest
2) VLDLs these are low denstiy, but large.
3) LDLs
4) HDLs. these high density lipids are the smallest, and
called good proteins.
What are proteins made up of?
one or more chains of amino acids, perhaps in a crazy ass
arrangement.
,describe amino acid structure.
Amino acids have 4 parts attached to the alpha carbon.
1. the amino group, which is NH2
2. the R group, which is one of 20 choices
3. the Carboxylic acid or C O O
the last thing attached to the Carbon is the Hydrogen.
What are the basic amino acids?
Hal
Histidine
Arginine
Lysine
What are the acidic amino acids?
Aspartic acid and Glutamic acid
, What are the nonpolar amino acids?
Poor LTMG Is Venezuelan At Parties
1) Phenylalanine
2) Leucine
3) Tryptophan
4) Methionine
5) Glycine
6) Isoleucine
7) Valine
8) Alanine
9) Proline
What is the primary structure of a protein?
Sequence of amino acids and
Location of disulfide bonds between cistine residues
What is the secondary structure of a protein?
1) Twisting of the alpha helix
2) Beta sheets
What is the tertiary structure of a protein?
3D structure including bending
