Acids and Bases Notes Part 1Litmus (blue or red)
What are Acids and Bases? Acids and bases are typical compounds present in a wide range of everyday commodities, including fruit juices and soft beverages, as well as soap. Acids and bases play a crucial part in our lives and the world around us, from our bodies to our planet’s seas...
Acids, Bases, and Salts (notes) Properties of acids: Sour taste (i.e. lemon) Release hydrogen ion (H+) into water Neutralize bases Corrode active metals Turn blue litmus paper to red Properties of bases: Bitter taste (i.e. soap) Release hydroxide ion (OH-) into water Neutralize acids ...

chemically, dna is composed of a pentose sugar, phosphoric acid and some cyclic bases containing nitrogen. the sugar moiety present in dna molecules is β-d-2-deoxyribose. the cyclic bases that have nitrogen in them are adenine (a), guanine (g), cytosine(c) and thymine (t). these bases...
ions, the solution will be more acidic. the lower the pka, similar to ph, the stronger the acid. as a result, the pka of sulfuric acid is lower than that of citric acid. acids and their conjugate bases are in a state of equilibrium. the stability of the base determines the acid’s...
Shen-Bai-Jie-Du decoction (SBJDD), a traditional Chinese herb formula developed based on evidence-based medicine, is efficacy to reduce the recurrence and carcinogenesis of colorectal adenoma. However, the mechanism of SBJDD to treat colorectal adenoma r
Urine cytology is a frequently used marker that has been approved to apply in adjuvant with cystoscopy, but its prominent defect in sensitivity has restricted its role in detecting low-grade diseases. In addition, many urine assays based on proteins, DNA, RNA, and other biomarkers, have also ...
Sequencing was performed on an Illumina NovaSeq6000 with two paired-end read cycles of 250 bases each (Illumina Inc., San Diego, CA; OE Biotech Company; Shanghai, China). Paired-end reads were preprocessed using Trimmomatic software to detect and cut off ambiguous bases (N). It also cut ...
phosphodiester bond. the nitrogen base attached to the pentose sugar makes the nucleotide distinct. there are 4 major nitrogenous bases found in dna: adenine, guanine, cytosine, and thymine. in rna, thymine is replaced by uracil. the dna structure is described as a double-helix or double...
