Watson Mrs. Lefever Biology 19 April 2010 Maple Syrup Urine Disease I. General Information -Maple Syrup Urine disease is an inherited disorder in which the body does not and is unable to process certain protein building block called amino acids leucine‚ isoleucine‚ and valine. -To treat this disease the infected would have to have a protein-free diet. Fluids‚ sugars and possibly fats are given through a vein (IV). II. Nature of this Mutation -Symptoms of this mutation

modern day Bolivians for thousands of years. One reason for its long lasting success as a staple food is its incredible nutritional value. Quinoa is one of the few plant foods known to contain all 26 amino acids‚ making it a perfect protein. What’s more‚ quinoa happens to contain most of these amino acids in proportions ideal for human consumption. In addition to the high amount of proteins‚ quinoa is an excellent source of magnesium‚ manganese‚ iron‚ and phosphorus. Iron especially is a mineral mostly

The Uses of water in Living Things Topics I have chosen to cover: - Osmosis & Water potential - Condensation & Hydrolysis Reactions - Digestion – the importance of water - Blood and tissue fluid To emphasise the sheer importance of water in living things and to put the content of this essay in to perspective‚ I am firstly going to inform you that the human body is approximately 50-75% water. Without water our body would be unable to successfully perform the numerous complex reactions and

are both types of fats except oils are unsaturated fats and waxes are saturated fats. 9. What is the relationship between fats and soaps? Soaps are made from fats by hydrolysis. Fats are glycerol with three fatty acids‚ and soaps are the sodium or potassium salts of fatty acids. 10. Explain the result of part four telling how you determined which type of biological molecule your sample contained? First‚ we obtained a test tube rack and 9 test tubes. We had three unknown solutions‚ A

To be used as feed it must be supplemented with essential amino acids e.g. Arginine and trytophan. The saponin in the cake is a powerful fish poison and the cake can be used to control predatory fish present in the pounds and lakhs.The cake is a cheap and effective wormicide to maintain the turf‚ lawn and golf

size 130 codons in length is seen to have cleavage in the presence of microsomes. The shorter sized mRNA’s in the presence of microsomes‚ are the non cleaved residue peptides in which the signal peptidase is unable to cleave the signal sequence amino acid. B. Band B is the cleavage of the signal sequence by the signal peptidase. The cleavage of the polypeptide weighs less then when the protein was attached to the signal sequence and before it grows in the ER lumen. This is evident from the diagram

deficiency in homogentisic acid 1‚2 dioxygenase‚ an enzyme that is found in the liver and plays a key role in the catabolism of amino acids such as phenylalanine and tyrosine. Due to the lack of homogentisic acid 1‚2 dioxygenase‚ the affected individual will experience a build-up of homogentisic acid in the body‚ namely in fibrous and cartilaginous tissue(ref1). Homogentisic acid is part of the catabolic chain from phenylalanine and tyrosine to fumarate and acetoacetic acid. Alkaptonuria received its
