Introduction: Proteins are necklaces of amino acids – long chains molecules. Proteins are the basis of how biology get this done. As enzymes‚ they are the driving force behind all the biochemical reactions which make biology work. As structural elements‚ they are main constituents of our bones‚ muscles‚ hair‚ skin‚ and blood vessels. As antibodies‚ they recognize invading elements and allow the immune system to get rid of the unwanted invaders. For these reasons‚ scientists have sequenced the

These advertisers claim that they have been promoting healthier products but nothing has proven that so far. Advertisers use cartoon characters to promote those high calorie foods and get children

The Hunger Games and Catching Fire is about 12 districts that fight in games where people get killed. The games are created by the capital and are watched by the people in the districts and capital.

outrageous promises to consumers. The latest in the fad diet trend is the “Low Carbohydrate/High Protein” diet. To break it down simply proteins are needed to help the body to grow and repair while carbohydrates provide energy. Both are needed in order for a person to remain healthy‚ which is why fad diets that promote one over the other are harmful to our bodies. Fad diets such as the “low carb/high protein” diet tend to have one thing in common. They promote the exaggerated benefits of their program and

Introduction: Protein texturization is a process of protein transform from a globular state to a fibrous physical structure that contains a sensation of eating meat. Texturized protein products have been defined as “fabricated palatable food ingredients processed from an edible protein source including among other soy grits‚ soy protein isolates and soy protein concentrate with or without suitable option ingredients added for nutritional or technological purposes.” (R.Y Yada‚ 2004) Protein products that

Carbohydrate Metabolism Carbohydrate metabolism starts with digestion in the small intestines. This is the site where monosaccharides are absorbed into the blood stream. This type of metabolism is basically considered to be glucose metabolism because carbohydrates are eventually broken down into glucose so that it can diffuse into the blood stream. There are three hormones in the body that control the concentration on glucose in the body: Insulin‚ glucagon‚ and epinephrine. If sugars are too
