Enzymes PT1 Flashcards
Organic catalyst prtoeins produced by living organisms
Enzyme
Facilitates or speed up the reaction. And maintains life
Catalyst
Temp for enzymes
Best at 35-40 optimal is 37 body temp
Enzyme only binds to a substrate or molecules w/ complementary
Shapes structure configuration
Active form has protein portion apoenzyme and non protein cofactor
Holoenzyme
Inorganic metal or organic vitamin
Cofactor
Inactive precurrsor of enzyme. Requires biochemical change to become active
Zymogen
What defiency cant produce tyrosinase
Albinism needing in converting melanin
Zn-carbonic anhydrase
Catalyzed H2CO3— H20+CO2
Mg-Hexokinase
Important in the glycolysis pathway
Ni-Urease
Catalyzed area—— NH3+co2
Cu-Cytochrome oxidase
Electrin transport chain
Cu-Tyrosinase
Converts tyrosine to melanin
FAD- Flavin adenine dinucleotide
Vit B2 transfer of electrons
NAD nicotinamide
Vit B3 transfer of electrons in oxidation reduction reacx
Pyridoxal phosphate-pyridoxine
Vit b6 transfer of aminogrp deamination reac
Thiamine pyrophosphate
Vit B1 transfer of aldehyde groups
Coenzyme A panthotetic acid
Vit B5 transfer of acyl group
Organic nutrients of various nature required in small quantites for multiple biochemical reactions for growth and survival
Vitamins
Most prominent function prosthetic group for enzymatic function
Coenzyme
History of vitamins
Hopkins 20th
Coined term vita= life +amine

Characteristics of Vitamins
Not synthesized by body
Non plastic
Not energy source
Essential vital process
Used for medicinal purposes non specific tool high dosage
Lack/deficiency of vitamin
Hypovitaminosis/avitaminosis
Overdose/toxic dose of vitamine
Hyper vitaminosis
Vitamins are destroyed by
Cooking or storage
Exposure to oxygen (vit C)
Exposure to UV light
Fat soluble vitamins
A,D,E,K
Water soluble
B complexes
B1,B3,B5,B6,B9,B12
