sugar and starch or are they pure protein?” This is important because the consumers might be falsely informed on what they are actually putting into their body. We are trying to answer this because it will provide the consumers with accurate results of what contents are within these supplements. In our study we had four testing reagents (Lugol’s which tests for starch‚ Biuret tests for protien‚ Benedict’s that tests for reducing sugars‚ and Ninhydrin which detects amino acids) and four stock

In this lab‚ there was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be

Before I start‚ I will say that I am 100% positive that my unknown (which was #31) is none other than Proteus vulgaris. My data and the ensuing results from them simply cannot be disputed. From my first batch of results‚ Proteus vulgaris reared its head

Exercise 4.4: Identification of Macromolecules in Household Substances The purpose of this lab is to determine the presence of glucose‚ starch‚ and protein in various samples through standard tests. Solution 1: Formula I believe formula will test positive for sugar and protein since it is supposed to be a nutritious‚ balanced drink for infants. Materials and Methods: Please refer to the Biology 1406 Lab Manual Pg. 43 Test For | Coloration/ Appearance of Positive Control | Coloration/

Macro molecules A macromolecule is a very large molecule commonly created by polymerization of smaller subunits. In biochemistry‚ the term is applied to the three conventional biopolymers (nucleic acids‚ lipids‚ proteins and carbohydrates)‚ as well as non-polymeric molecules with large molecular mass such as lipids and macrocycles. The individual constituent molecules of macromolecules are called monomers(mono=single‚ meros=part). Usage The term macromolecule was coined by Nobel laureate Hermann

Macromolecules Biologically‚ there are four general types of macromolecules or biomolecules. They are carbohydrates‚ proteins‚ lipids and nucleic acids. Each of these plays an important role in maintaining life among living creatures and each is a piece of the elaborate puzzle of metabolism. Each has a different chemical composition and interacts with other molecules differently. Most of these biomolecules come from food sources and we are therefore already familiar with them. Without a

The weight of the beaker was subtracted from the weight of the beaker and sand. The result was then divided by the original weight of the mixture to determine the
