electrophoreis w/ arginine, alanine, & aspartic acid-what happens
Describe what would happen if you conducted an electrophoresis of a mixture of arginine, alanine, and aspartic acid, using a buffer with pH of 7.0. Should you place the mixture of amino acids at one end of the starch gel or in the middle? A diagram may help. **I know that smaller peptides migrate fastest so Alanine, asparti ...continues

Lower solubility in water: Glucose or stearic acid Lower pH in solution: Butanoic acid or 1,5-butanedioic acid Higher melting point: Trans-CH3(CH2)5CH=CH(CH2)7COOH or Cis-(same compund) **Please briefly explain why so I can understand and be apply to apply in future
how conditions alter rate of enzyme-catalyzed reaction
How will each of the following changes in condition alter the rate of an enzyme-catalyzed reaction: -decreasing temp to 10 deg C? -increasing the pH of the solution from 7 to 11? -heating only the enzyme to 100 deg C?

momsaccharides/products, linkage, benedicts, acetal etc
Please see attached for diagram ... Questions: Will this disaccharide give a positive Benedict's test? Why or why not? Does this structure have a hemiacetal, hemiketal, acetal, or ketal system? Locate it on the drawing & give appropriate label. Upon hydrolysis with the appropriate enzyme, what will be the products? ...continues
