Biochemistry 2 Flashcards
essential amino acids
only found in the found
amino acid
has an nitrogen = amino and carboxly group have called functional group
functions of proteins-learn five
collagen, haemoglban, imume functons, cell memebranes
how does heat break a bond
due to kinetic energy, moves the bonds apart
heavy metal- damage proteins
metal chorella hel to remove heavy metal
DNA is made of nucelootide
it made up of four groups
pohaspahe, sugar , nitrogenous base
the neculotide base is different
A,G, C, T
bonds between the based pairs are called
hydrgen bonds
The bond between the phosphate and sugar
Covalent bond- very strong- back bone
dna
code for making proteins
the ribsome reads the copy of rna
3 at a time
mutation
a change to the nucleotide bases
A mutation
No protein or not quite correct.
E.g AAA GGG CCC delete AAG, GGC CC = mutation
chormosome ?
DNA is a condense form. The end of the chorosome is called telemeres.
What happens telomers get shorter
Aging, - stress- poor nutrient, lack of exercise=, negative thoughts
Gotu Kola
It cause it reduce telomeres shortness
mutation
the protein changes e,g sickle anaemia
enzymes
Proteins, you can control how much the gene have to opened and copied
the expression of genes can be also be influence by certain nutrients
enzymes are proteins- coded by DNA
B9 folate - active forem
Metylfolate - active form involed
The coversion can onlyhapen it has an enymes called homocysteine
enzymes
lowers the activation enzyme for a reaction to occur fast.
Speeds up reactions.
every enzyme is highly specific , what is unique for
Active site fits with a substrate
what is enzyme substrate complex
when the enzymes and substrate for together
what does the enzymes want to do ?
enzymes stress the bonds of the substrate and released - new products Break the substrate- a ( proteins)
enzymes cofactors
Increase the activity of enzymes. Can in inactive if you do not have the right cofactors.
They also help with the binding process
