Collagen's insolubility was a barrier to the study of monomeric collagen until it was found that tropocollagen from young animals can be extracted because it is not yet fully crosslinked. However, advances in microscopy techniques (i.e. electron microscopy (EM) and atomic force microscopy (AFM)) and X-ray diffraction have enabled researchers to ...

Glycine, proline, and hydroxyproline must be in their designated positions with the correct configuration. For example, hydroxyproline in the Y position increases the thermal stability of the triple helix, but not when it is located in the X position. [4] The thermal stabilization is also hindered when the hydroxyl group has the wrong ...
Lower levels of damage in some species of sponges cultured via mesh bags can lead to higher levels of survival. Growth rates may be decreased as mesh strands on the bags may decrease water flow, limiting food availability. [21] The accumulation of biofouling agents such as bryozoans, ascidians and algae on the mesh may further limit water flow ...
Some modern authors prefer to exclude multicellular organisms from the traditional definition of a protist, restricting protists to unicellular organisms. [9] [10] This more constrained definition excludes all brown, the multicellular red and green algae, and, sometimes, slime molds (slime molds excluded when multicellularity is defined as ...
The tendency is to have even more traits in the future. For example, disease resistance, reproductive traits, robustness, lower emissions, feed conversion ratio (sustainability traits). New technologies for high-throughput phenotyping, as in the concept of precision farming, mean that many novel traits might be included as well.
Salmon pens off Vestmanna in the Faroe Islands, an example of inshore mariculture. Mariculture, sometimes called marine farming or marine aquaculture, [1] is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater.
The presence of water (an aldehyde) has been shown to decrease the stiffness of collagen fibrils, as well as increase their rate of stress relaxation and strength. [4] From a biological standpoint, water content acts as a toughening mechanism for fibril structures, allowing for higher energy absorption and greater straining capabilities.
