Title: Testing For Macromolecules Objective: Introduction Proteins are complex molecules which consists of carbon‚ oxygen‚ hydrogen and nitrogen. All proteins are made up of one or more polymers‚ known as polypeptides. Its monomers are amino acids. Protein can be divided into primary structure‚ secondary structure‚ tertiary structure and quaternary structure. It is important for all living things in the world as they form enzymes‚ antibodies and hormones. Materials and Procedures: Results

where layers of glycine side chains alternate with layers with alanine and serine side chains. Collagen is the main protein component of connective tissue. Collagen is found in tendons and cartilage. Every third residue is glycine. The other amino acids are proline and hydroxyproline. Collagen‚ therefore‚ forms a triple helical structure with strong tensile strength. Collagen molecules have the ability to aggregate to form fibrils. These fibrils are covalently cross-linked by derivative groups

Proteins are large biological molecules that are made up of one or more chains of amino acids. Proteins perform many different functions within a living organism‚ such as catalysing metabolic reactions‚ replicating DNA‚ responding to stimuli‚ and transporting molecules from one location from another. All proteins differ from each other primarily by their sequence of amino acids which is usually determined by a nucleotide sequence of their genes‚ resulting in a three-dimensional fold that determines

GENERAL BIOCHEMISTRY Problem Set No. 1 Answered by: Andrea Rose A. Fajardo of BSFT 2-1N 1. Calculate the pH of a dilute solution that contains a molar ratio of potassium acetate to acetic acid (pKa=4.76) of: a. 2:1 pH = 4.76 + log[2]/[1] = 4.76 + 0.3010 = 5.06 b. 1:4 pH = 4.76 + log[1]/[4] = 4.76 + (-0.6021) = 4.16 c. 6:5 pH = 4.76 + log[6]/[5] = 4.76 + 0.0792

(Lovett‚ Richard) 90% of adults consume caffeine daily in different ways. Most of the energy from these drinks comes from the sugar and caffeine not the unnecessary extras (Suzanne Farrell MS‚ RD). Taurine another main ingredient is actually an amino acid that is found in the human body it is a natural substance that our bodily systems encounter every day. However in these energy drinks it is a synthetic element. Then there is Ginseng is known as an adaptogen‚ which means it increases resistance

link to the β-1‚6 glucan in the cell wall of C. albicans. Als proteins all have a similar structure which includes; an N-terminal secretory signal sequence‚ followed by an NT domain which is in the region of 320 amino acids‚ a TR domain of a Ser/Thr rich repeated sequence‚ a 104 amino acid T domain and a Ser/Thr rich C domain which varies in both size and sequence (Segui‚ 2004). The size of these glycoproteins is believed to be in between the range of 440 and 600kDa. In addition to adherence to mammalian
