2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH 3) 3 CCH 2 CH(CH 3) 2. It is one of several isomers of octane (C 8 H 18 ). This particular isomer is the standard 100 point on the octane rating scale (the zero point is n -heptane ).

A food pyramid is a representation of the optimal number of servings to be eaten each day from each of the basic food groups. [2] The first pyramid was published in Sweden in 1974. [ 3 ] [ 4 ] [ 5 ] The 1992 pyramid introduced by the United States Department of Agriculture (USDA) was called the "Food Guide Pyramid" or "Eating Right Pyramid".
2,2,4-Trimethylpentane, also known as isooctane, is an octane isomer which defines the 100 point on the octane rating scale (the zero point is n-heptane). It is an important component of gasoline . Isooctane is produced on a massive scale in the petroleum industry, usually as a mixture with related hydrocarbons.
Triptane, or 2,2,3-trimethylbutane, is an organic chemical compound with the molecular formula C 7 H 16 or (H 3 C-) 3 C-C(-CH 3) 2 H. It is therefore an alkane , specifically the most compact and heavily branched of the heptane isomers, the only one with a butane (C 4 ) backbone.
Part of this growing trend is the commercialization of home-made dog food for pet owners who want the same quality, but do not have the time or expertise to make it themselves. [60] The advantage is forgoing the processing stage that traditional dog food undergoes. This causes less destruction of its nutritional integrity.
Vegan dog food may incorporate the use of fruits, vegetables, cereals, legumes including soya, nuts, vegetable oils, as well as any other non-animal based foods. [2] The omnivorous domestic dog was originally primarily carnivore but has evolved to metabolize carbohydrates, fat, and fiber and remain healthy on a diet lower in protein. A ...
