11S globulin family is a family of globulin proteins chiefly found in seeds of legumes (legumin-like), [1] along with 7S family, often found in a protein fraction within a protein isolate. They are used as storage of important nutrients for plant growth, and therefore hardy enough to pass through the human digestive system unscathed.
Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method based on Stokes' law.
They are classified as 11S globulins based on their sedimentation coefficient, and are salt soluble neutral glycoproteins. [2] [3] Their molecular weights range from 20 to 40 kDa. They comprise up to 50–70% of the total seed protein. Cruciferin is a comparatively larger seed storage protein than napin. It is composed of two polypeptide chains ...
The sedimentation coefficient is typically dependent on the concentration of the solute (i.e. a macromolecular solute such as a protein). Despite 80+ years of study, there is not yet a consensus on the way to perfectly model this relationship while also taking into account all possible non-ideal terms to account for the diverse possible sizes, shapes, and densities of molecular solutes.

Soil structure affects aeration, water movement, conduction of heat, plant root growth and resistance to erosion. [26] Water, in turn, has a strong effect on soil structure, directly via the dissolution and precipitation of minerals, the mechanical destruction of aggregates [27] and indirectly by promoting plant, animal and microbial growth.
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
Floristic Quality Assessment (FQA) is a tool used in the United States to assess an area's ecological integrity based on its plant species composition. [1] Floristic Quality Assessment was originally developed in order to assess the likelihood that impacts to an area "would be irreversible or irretrievable...to make standard comparisons among various open land areas, to set conservation ...
Further, they can distinguish between different land-based plants, depending on the type of photosynthesis they undergo. Therefore, the C/N ratio serves as a tool for understanding the sources of sedimentary organic matter, which can lead to information about the ecology, climate, and ocean circulation at different times in Earth's history.
