Proline and Lysine residues of collagen are hydroxylated by proline hydroxylase and lysine hydroxylase right after synthesis and this modification is for proper connective tissue function of Collagen. These 2 enzymes require 4 cofactors; Fe++, O2, Vit C & alpha-ketoglutarate. So I'd say; "Keep Our Collagen Fine" to memorize these molecules :wink:
Just to remind; Lysine Hydroxylase gene is mutated in Ehlers Danlos, also know as "Ehlers Danlys"  :arrow: hyperelasticity and fragility of the skin, hypermobility of the joints, and fragility of the cutaneous blood vessels, etc.

I need to memorize the structures (not just the hydrophobicity, esstential, etc, I need to be able to draw them).
Anyone know any good tricks to memorizing the structures for all 20 amino acids?
Thanks!

I always forget competitive and non-competitive inhibition on linewiever burk graph.so i made this.
in competitive inhibtion there is always competetion between two lines so they cross on graph.So solute concentration chages but velocity remains same.vice versa for non competitive.

km always higher than vmax like either km inc and vmax same or km same vmax dec
kmpitative inhibitor ==km increase ,vmax same
non kmpitative inhibitor==== km not increased, vmax decreased

Learning the Cofactors for Enzymes is Painful so you hit them with a BAP!
BAP! Tender Loving Care for Noone!
(BAP needs TLCFN)
Branched Chain Ketoacid DH
Alpha ketoglutarage DH
PDH
(by the way, all are DH enzymes; ALL DH enzymes produce NADH)
they need:
TTP from Thiamine (B1)
Lipoic Acid (Synthesized; not from a vitamin)
CoA (from Pantothenate)
FAD(H2) from Riboflavin (B2)
NAD(H) from Niacin (B3)
To remember what TLCFN comes from its: BSPRN (bull sh.. prn)
Another one:
Carboxylases need ABC:
ATP, Biotin, CO2
All Dehydrogenases: make NADH
All Kinases: Phosphorylate (KINdly put a phosphate on)
All Phosphatases: DEphosphorylate (PhosphaTASE, TAKES off Phosphate)
Glucagon puts Phosphate ON (phosphorylates); and INversely INsulin does the opposite (dephosphorylate)
This is a good way to remember what enzymes of which pathways are active/inactive in phosphorylated/dephosphorylated form
eg. Insulin activates Glycolysis, and Glycogen synthesis, so the enzymes that it activates in those pathways will be active in DEphosphorylated form.
and: Glucagon activates Glycogenolysis and Gluconeogenesis, so the enzymes that it activates in those pathways will be active in Phosphorylated form.

A little tragic no one has taken up the Peppermint patty question.
My guess is it refers to Xeroderma pigmentosa, an autosomal recessive disorder of DNA repair. Humans typically utilize DNA excision repair, etc. to repair Thymidine dimers caused by exposure to UV light (UVB). There does exist another utilization to specifically fix these dimers called DNA photolyase, however if ever on a question this answer MUST be wrong since humans do not produce photolyase. Mutations in DNA excision repair mechanisms on the XP genes can cause build-up of thymidine dimers, which causes DNA damage, which of course leads to mutations and problems of expression. The end result is these patients have freckles, photosensitivity, and a propensity to have "paper-like skin". They also develop Basal and Squamous carcinomas and Actinic keratoses.

not a mnemonic but an observation:
all amino acids that start with T are ketogenic and glucogenic
threonine
tyrosine
tryptophan
all amino acids that start with A except arginine are non-essential
aspartate
alanine
asparagine

gene expression
what binds what?
oPERator-->rosserPER (REPressor)
Enhancer?
E goes with F So enhancer with Factor transcription
PromoteR --> Polymerasse Rna
I keep confusing these and this is the only silly way which helps.if anyone has better ideas PLEASE post

RNA polymerase III-->tRNA
Three goes with T
mRNA--> choose m for Middle number
so RNA poly II--> mRNA
RNA poly ONE is the Real ONE
poly I--> rRNA
