Functional Groups

87.6K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Functionalism

2.5K
William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.
James envisioned psychology's...

Mechanical Protein Functions

5.5K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Structural Protein Function

29.8K
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to...

Area of Science:

  • Microbiology
  • Immunology
  • Ecology

Background:

  • Advances in data collection reveal links between host-associated microbial community imbalance (dysbiosis) and human illnesses.
  • Dysbiosis is a central concept for understanding the human microbiota's role in health and disease.
  • Defining dysbiosis solely by cataloging microbial species is problematic.

Purpose of the Study:

  • To provide a functional definition for dysbiosis.
  • To propose a theoretical framework for microbiota research incorporating the germ-organ concept, ecological assumptions, and immunological principles.

Main Methods:

  • Literature review and theoretical synthesis.
  • Integration of ecological and immunological principles.
  • Application of the germ-organ concept to microbiota research.

Main Results:

  • A theoretical framework for microbiota research is proposed.
  • This framework offers a functional definition of dysbiosis.
  • The framework highlights the importance of immune mechanisms in maintaining microbial balance.

Conclusions:

  • A functional definition of dysbiosis can be achieved through an integrated theoretical framework.
  • Future research should focus on the mechanistic underpinnings of dysbiosis.
  • Weakening of immune mechanisms is often implicated in dysbiosis.
