- パニクル窒素肥料 (N2;45kg N ha−1) が米に与える影響を調査した.
- 密度と安定性を含む,アミロペクチンの構造の変化を分析した.
- アミロペクチン-タンパク質 (グルテリン/プロラミン) 複合体の形成と,粉の粒子の性質 (結晶性,マイクロストレイン,間隔) を評価した.
主要な成果:
- N2治療は,鍵となるアミロプクチン密度 (例えば,2A4B1B2B3) を著しく増加させ,アミロプクチン-タンパク質複合体の形成を促進した.
- 最適化されたアミロプクチンの構造は,安定性が向上し,溶媒にアクセシブルな表面積を示した.

The Nitrogen Cycle
60.7K
Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Protein and Protein Structure

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.

Structural Protein Function

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...

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.
