What is the structure of an amino acid?
They all make sense
What is carboxylate?
A carboxyl group thats lost a proton
(bc its bc its lost so its late, and it is sad so it lost a positive)
What type of amino acids are the 20 amino acids?
a-amino acids
(bc they are the main)
What are a amino acids?
amino acids in which amino and carboxyl groups are bound to the same carbon atom.
What is the zwitteron?
Zwitteron is the dominant species in aqoues solutions.
What is the aa that is an exception to the d and L?
glycine
What is the form that mamalian proteins exist in?
L-form
(Levo)
bc mst people arent mslm
What is the structure of proline?
a cyclic structure
(bc its line has a pro formation (stable))
What is the only secondary amino acid?
proline
Why is proline considered secondary? What is another name for it?
bc its amine nitrogen is bonded to two carbons
another name: imino acid (bc I am a pro)
(it is pro, so stronger, so two bonds, and the pro has to be a name, so amine)
What are the branched amino acids?
valine, leucine, isoleucine
What disease causes abnormal metabolisim of branched amino acids?
Maple syrup disease
(bc wmn like maple syrup)
What is the significance of the aromatic side chains of aromatic aa’s?
It allows us to locate and measure proteins.
What are the aromatic amino acids?
pheynlalanine, tryptophan, tyrosine
(aladeen uses perfrume) (the smell of the perfume makes you tryp, tryptophan, tyrosine) (it makes you tired on the scene)
What are the three exceptions to the abbreviations?
Asparagine (Asn)
Glutamine (Gln)
Isoleucine (Ile )
What does methionine contain?
sulfur
(blue like meth)
What does cystenie contain?
sulfhydryl group (-SH) that can form disulfide bonds (disulfide bridge) to stabilize the shape (tertiary structure) of proteins
(bc cyst is like a bridge between two parts of skin)
What are the aa’s that are used for phosphorylation?
Please send the tyre
Please: phosphorylation
Send: serine
The: threonine
Tyre: tyrosine
What aa’s serve as attachment points for oligosaccharides in glycoproteins?
amide group of asparagine,
and hydroxyl of serine and theronine
What group plays a role in the folding of proteins?
R group
(bc it is variable so it can fold)
non polar
Non Polar:
No: non polar
Pro: proline
Tries: tryptophan
All: alanine
Good: glycine
VeryMint: valine and methionine
Icecream: isoleucine and leucine
Phenomenally: phenylalanine
uncharged
Uncharged:
U: uncharged
Got: glutamine
To: tyrosine
See: Serine
The: threonine
Absolute: asparagine
Chaos: cysteine
acidic
Acidic:
Fairly easy as it is just aspartic acid/aspartate and glutamic acid/glutamat
basic
Basic:
B: basic
L: lysine
A: arginine
H: histidine
