Organic Compounds: Organic compounds are compounds that generally consist of carbon-hydrogen bonds. It may also be compounds with carbon atoms that are covalently bonded to elements such as oxygen and nitrogen. Furthermore, the study of the reactions, synthesis, and properties comprises the field of...
The main components(amino acid,soluble sugar,soluble protein,total flavonoids,ascorbic acid,chlorogenic acid,quercetin and baicalin)of four cultivars of edible chrysanthemum flowers(SYJ1,SYJ2,SYJ3 and SYJ4)were determined by titrimety,ultraviolet spectrophotometry and HPLC methods. The chemical compositio...
What organic compounds are present in the cell that aren't one of the four main groups (lipids, nucleic acids, amino acids, and carbohydrates)? Explain the basic structure of proteins. Give at least two major functions. What is the directionality of the macromolecules, carbohydrates, ...
A total of 37 VOCs, mostly aliphatic compounds, were detected from the fourCeropegiaspecies (Table3). Each species only had four to five main compounds, i.e., present in proportions > 5%. These main compounds were not species-specific but their abundances varied among species. The most...
