Antibiotics such as polymyxin B and polymyxin E (colistin) bind to phospholipids in the cell membrane of the bacterium and interfere with its function as a selective barrier; this allows essential macromolecules in the cell to leak out, resulting in the death of the cell. Because other cells,...
polymer, any of a class of natural orsyntheticsubstances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units calledmonomers. Polymers make up many of the materials in living organisms, including, for example,proteins,cellulose, andnucleic acids. Moreov...
Types of Fatty Acids There are numerous types of fatty acids in the fats and oils from food that are either saturated, monounsaturated, or polyunsaturated. Some examples of fatty acids commonly found in foods include: Saturated fatty acids: palmitic, stearic, myristic, and lauric acid ...
Proteins are macromolecules build with amino acid blocks. They form the body mass and provide energy for development and growth. Proteins are found in various food items like legumes and meat.Answer and Explanation: The amino acid...
properties of PBBFs of different nanocellulose types vary significantly.The spatial distribution of different nanocellulose types in the protein matrix varies.PBBFs of different nanocellulose types have various intermolecular crosslinking levels.The presence of lignin enhances the material's creep properties....
Glycosidic linkage is a structure found in tea, sugar, mushrooms, plants, DNA, and other living organisms. Only sugars with the cyclic forms have an anomeric carbon and are capable of forming a glycosidic link. An anomeric carbon can be identified as the carbonyl carbon in the open-chain ...
CNC was found to enhance the viscosity of starch during the pasting process, while also hindering its short-term retrogradation. By incorporating CNC, the gelatinization enthalpy of starch paste was altered, improving its shear resistance, viscoelasticity, and short-range ordering, leading to enhanced...

Virtually all synthetic adhesives and certain natural adhesives are composed ofpolymers, which are giant molecules, or macromolecules, formed by the linking of thousands of simpler molecules known as monomers. The formation of thepolymer(a chemical reaction known as polymerization) can occur during a“...
In this article, the major commercially employed polymers are divided by thecompositionof their “backbones,” the chains of linkedrepeating unitsthat make up the macromolecules. Classified according to composition, industrial polymers are eithercarbon-chain polymers(also called vinyls) orheterochain poly...
