まとめ
リンゴジュースの摂取は唾液の潤滑とタンパク質のレベルに一時的に影響します. 唾液の臨時脱脂を引き起こしますが,摩擦とタンパク質濃度への影響は限られ,可逆です.
科学分野:
- 口腔生物学
- バイオマテリアル科学
- トリボロジー
背景:
- 唾液の潤滑性は 口腔の健康と機能に不可欠です
- 酸性飲料は唾液の組成と性能を変化させる可能性があります.
- 飲料が唾液に与える影響を理解することは 口腔衛生の研究にとって不可欠です
研究 の 目的:
- リンゴジュース (J) が人間の唾液のトライボロジカル特性,粘着性,タンパク質濃度に与える影響を調査する.
- 唾液の潤滑行動と吸収された唾液膜に対するJと水の (コントロール) 効果を比較する.
- これらの効果の一時的な性質を評価する.
主な方法:
- 32人の健康な成人の唾液のトライボロジカル測定
- 唾液膜を分析するクォーツ結晶マイクロバランス (QCM-D)
- 総タンパク質濃度 (TPC) とSDS-PAGEを含むタンパク質分析
主要な成果:
- 水とJの両方が唾液の摩擦を増加させ,水はより大きな初期脱脂を引き起こしました.
- 摩擦係数は10分以内に基準値に戻り,一時的な効果を示した.
- Jは唾液膜を変化させ 硬化させ シスタチンや炭酸水素のような特定の唾液タンパク質に影響を与えました
結論:
- リンゴジュースの摂取は,唾液の脱脂と吸収に限られ,一時的な効果がある.

The Physiology of Taste
4.2K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Salivary Glands and Saliva
949
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

Protein Buffers in Blood Plasma and Cells
1.7K
The human body utilizes protein buffer systems to maintain a stable pH. These systems capitalize on the dual role of amino acids, which can act as acids or bases by accepting or releasing hydrogen ions in response to pH changes. Protein buffer systems are particularly significant in the extracellular fluid (ECF) and intracellular fluid (ICF) of active cells, where structural and functional proteins provide substantial buffering capacity.

Titration of Polyprotic Base with a Strong Acid
864
The titration of a polyprotic base such as sodium carbonate with a strong acid such as hydrochloric acid results in two equivalence points on the titration curve. At the first equivalence point, the carbonate ions in the base are completely converted to bicarbonate ions. The second equivalence point corresponds to the complete conversion of bicarbonate ions to carbonic acid, which dissociates into carbon dioxide and water. The region before the first equivalence point corresponds to the...

Factors Affecting Solubility
33.9K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Colloids

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...
