A macromolecule is a large molecule made up of smaller units called monomers. It can be found in both natural and synthetic materials and has a complex structure that influences its properties. Examples of macromolecules include proteins, DNA, RNA, and synthetic polymers. AI generated definition ba...
A macromolecule is made by joining together many smaller molecules. Which of the following chemicals is not an example of a macromolecule? a) The carbohydrate cellulose. b) The fat/lipid glyceryl tristearate (present in beef fat). c) The nucleic acid DNA. Which two functional groups are in ...
解析 Macromolecule (polymers) in a suitable solvent form solutions in which the size of themacromoleculesmay be in the colloidal rangeand the system is known asmacromolecular colloids. E.g.: starch, cellulose, enzymes, proteins, nylon, polystyrenein a suitable solvent. ...
Molecular weight cut off (MWCO): Mean pore radius of the membrane can be measured by rejection test using solute of higher molecular weight compound (such as PEG and polyethylene oxide; PEO). According to Stokes-Einstein equation, stokes radius (a) of a macromolecule can be found from its ...
14 Besides, chitosan mucoadhesives are limited in their ability to “unload”, since a large proportion of the bioactive molecule remains trapped in the mucus/chitosan complex and is passed along the alimentary canal. Thiomers or thiolated polymers are an example of a more recent development of...
it is striking that most of the best hit homologs of enzymes of central metabolism are proteins ofV. cholerae. This is particularly puzzling sinceV. choleraeis a mesophile and it is phylogenetically in a different Order and Family fromP. ingrahamii. Could this be an example of massive horizont...

In addition to predicting patterns of diffusion within single cells, the inside-out model has implications for syncytia generated by nuclear division. Within such syncytia, cytoplasm tends to be under the local control of individual nuclei. As an example of this, individual nuclei in theDrosophilasy...
36 Such remarkable progress is partly due to the inherent slow diffusivity or high effective viscosity of macromolecules.37, 38 That is to say, the diffusion coefficient (D) of a macromolecule is inversely proportional to the square of the degree of polymerization (N), υiz. D≈ N−2. ...
