Amino Acids Glycine is the smallest of the amino acids. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH‚ glycine will exist predominantly as the zwitterion. Alanine is a hydrophobic molecule. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. The α carbon of alanine is optically active; in proteins‚ only the L-isomer is found. Serine differs from alanine in that one of the methylenic

Jarriette kenn D Patenio Jaymar patana Job madronal Do all ideal gases have the same molar volume? An ideal gas has the following equation of state (an equation which relates various thermodynamic properties for a substance‚ such as pressure‚ temperature and molar volume): Pv = RT P - pressure v - molar volume R - universal gas constant T - absolute temperature Clearly the molar volume depends on temperature and pressure‚ so if two gases are at different conditions then they

Silicon dioxide (SiO2) is one of the most common oxides on the surface of earth. Like most oxides‚ it adopts a polymeric structure. Оксидите се хемиски соединенија што содржат најмалку еден атом на кислород и еден атом од друг хемиски елемент во својата формула. An oxide /ˈɒksaɪd/ is a chemical compound that contains at least one oxygenatom and one other element[1] in its chemical formula. Metal oxides typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth’s crustconsists

Chapter:-8 The d-and f-Block Elements POINTS TO BE REMEMBERED: --- The elements of periodic table belonging to group 3 to 12 are known as d-Block elements. The general electronic configuration of these elements is (n -1)d1-10 ns 1-2 d- Block elements are collectively known as Transition Elements because properties of these elements vary in between s-Block and p-Block elements. A transition element should have partially filled (n-1) d orbital. Group 12 elements i.e. Zn

Skeletal muscle is associated with the bony skeleton and consists of large cells that bear striations and are under voluntary control. 2. Cardiac muscle occurs only in the heart and consists of small cells that are striated and under involuntary control. 3. Smooth muscle is found in the walls of hollow organs and

protein (LTBP) and latency-associated peptide (LAP). Serum proteinases such as plasmin catalyze the release of active TGF-beta from the complex. This often occurs on the surface of macrophages where the latent TGF-beta complex is bound to CD36 via its ligand‚ thrombospondin-1 (TSP-1). Inflammatory stimuli that activate macrophages enhance the release of active TGF-beta by promoting the activation of plasmin. Macrophages can also endocytose IgG-bound latent TGF-beta complexes that are secreted by plasma

Chronic Consumption of Ethanol Alcohol and Neurological Dysfunction Ethanol Alcohol‚ commonly known as Alcohol is the primary mood altering drug used in the United States of America. When alcohol is consumed it is absorbed unaltered by the stomach and the small intestines. Then the ethanol molecules are distributed evenly to all of the tissues and fluids of the body. The alcohol present in the bloodstream is metabolized by the liver through three pathways. The major pathway involves an enzyme
