trigger the monocytes which then become macrophages. The macrophages become activated by the cytokine and begin to attack any tissue in its general vicinity. This could lead to severe tissue damage. (Martz‚ n.d.) Urushiol is made up of a mixture of catechol derivatives‚ the most common found on poison ivy being pentadecylcatechol. Although many people believe that poison ivy is harmless after the plant has died‚ that isn’t the case. Urushiol has been found to stay on a surface for several years. The

Parkinson’s disease is caused due to the production of insufficient dopamine synthesis in brain….. Degradation of catecholamines The catecholamine is inactivated by oxidative deamination by monoamine Oxidase (MAO) and by o-methylation carried out by catechol-o-methyl-transferase (COMT) as the one-carbon donor. -Two reactions can occur in either direction -the aldehyde products of the MAO reaction are oxidized to the corresponding acids MAO: Inactivates Catecholamine by Oxidative Deamination to

Part 1 dilutions participated as a trail run to gather around the “full enzyme” that was used for the other parts of the experiment. Part 2 readings were in the time span of 10 minutes and the final results show a spontaneous increase in the first minutes of the absorbance readings. They then showed a steady reading towards the end of timing. The amount of enzyme is decreasing as the dilution occurred. The activity it catalyzes measures the amount of enzyme present in the reaction (Introduction to

Dopamine and the related substances norepinephrine (NE) and epinephrine (EPI) comprise a small but important group of neurotransmitters and hormones called catecholamines. * Catecholamine contains two chemical similarities: a core structure of catechol and a nitrogen-containing group called an amine. The catecholamines‚ in turn‚ belong to a wider group of transmitter called either monoamines (transmitters that possess one amine group) or biogenic amines * EPI – adrenergic. NE- noradrenergic

PARKINSON’S DISEASE NAME: INSTITUTION: Introduction Parkinson ’s disease is a regarded as a common neurodegenerative condition. The etiology of the disease has not completely been understood‚ but the condition has been associated with a confluence of factors. The first is the loss of a number of neurotransmitters‚ most notably dopamine that produces neurons in the pars compacta of the substantia nigra. It has also been linked to the combined effects of environmental exposures and aging

new enzyme formed is called dopamine. Dopamine is then hydroxylated‚ and turns into norepinephrine. Lastly‚ norepinephrine is methylated to form epinephrine. Through the process of chemical synthesis epinephrine can be produced by the reaction of catechol and chloroacetyl chloride. This then reacts with methylamine. This is reduced to a hydroxylic compound. The result of this is epinephrine. Using tartaric acid‚ epinephrine can be separated. I chose to research epinephrine because of the difference

Introduction: With the execution of this experiment‚ we began to go deeper into the Cell and Molecular Biology course. The main focus of the experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign

Neurotransmitters are brain chemicals that transmit information throughout our brain and body. They transmit nerve signals electrically and chemically between neurons. Neurotransmitters can affect mood‚ sleep‚ concentration and weight. The two kinds of neurotransmitters are: inhibitory and excitatory which‚ respectively‚ calm and stimulate the brain. Dopamine is an inhibitory neurotransmitter so when dopamine reaches the receptor sites‚ it blocks the neuron from firing. Dopamine is produced in multiple

Guava is a small tropical tree that grows up to 35 feet tall; it is widely grown for its fruit in tropics. It is a member of the Myrtaceae family‚ with about 133 genera and more than 3‚800 species. The leaves and bark of P. guajava tree have a long history of medicinal uses that are still employed today (Nwinyi et al.‚ 2008). In the view of the immense medicinal importance of P. guajava plant evidenced in the various studies mentioned above and also corroborated in a recent review article by Kamath
