概括
甜味适应,即经过多次暴露后感知甜味的下降,是由甜味剂成分驱动的,而不是通常使用低热量甜味剂 (LCS). 将糖与糖混合会减少这种适应.
科学领域:
- 感官科学 感官科学
- 神经科学是一个神经科学.
- 食品科学 食品科学 食品科学
背景情况:
- 甜味适应,重复暴露后感知甜味的减少,影响饮食选择.
- 像糖这样的低热量甜味剂 (LCS) 可以比糖类引起更大的适应,但混合物可能会减轻这一点.
- 个人在LCS消费习惯中的差异可能会影响味觉.
研究的目的:
- 为了确定习惯性LCS消费是否会改变甜味感知和适应.
- 调查是否与糖混合苏克拉洛斯减少了甜味适应.
- 为了比较人类和动物模型对糖,糖和它们的混合物的适应反应.
主要方法:
- 人体感官测试涉及习惯性 (HC) 和非习惯性 (NHC) LCS消费者在重复试验中评价甜味.
- 在小鼠体内成像,使用微流体舌头系统来评估神经对甜味剂的反应.

The Physiology of Taste
7.1K
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...

Gustation
51.9K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

Taste Buds and Receptors
4.6K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Glucose Transporters
27.2K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
522
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.

Sugars as Energy Storage Molecules
9.8K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...
