Understand Your Fats and Fiber Christy White SCI/241 August 29‚ 2013 Simyka Carlton The fats are Trans‚ saturated‚ mono-saturated‚ and polyunsaturated. The bad fats are Trans fats and saturated fats. These fats are generally found in the foods that we all love but know that we shouldn’t eat‚ or at least eat in moderation. Saturated fats are found in foods like butter‚ milk‚ cheeses‚ and meats. Trans fats are found in foods like cakes‚ cookies and other types of baked goods as well as deep

known as fatty acids. They are classified either according to saturation or based on molecular length and size of the carbon chain within each fatty acid. Monounsaturated fats and polyunsaturated fats are an example of the first class. The second classification is based on molecular size or length of the fatty acid’s carbon chain. Long chains of carbon atoms consist of each fatty acid with an attached hydrogen atom. There are short chain fatty acids known as SCFA‚ medium chain fatty acids (MCFA) such

[3] Hydrolytic rancidity[edit] Hydrolytic rancidity occurs when water splits fatty acid chains away from the glycerol backbone in triglycerides (fats). The chemical term is ester hydrolysis. Usually this hydrolysis process goes unnoticed‚ since most fatty acids are odorless and tasteless. A particular problem arises with butter‚ which contains triglycerides with a high content of butyric acid derivatives and acetic acids. Oxidative rancidity[edit] Oxidative rancidity is associated with the degradation

tongue releases an enzyme called lingual lipase that plays: • In Adults: A minor role in the digestion in adults. • In Infants: An active role in infants. In infants‚ this enzyme efficiently digests the short-and medium- chain fatty acids found in milk. In Oesophagus: This is a simple tube through the thorax‚ which connects the mouth to the rest of the gut. No digestion takes place in oesophagus. There is a thin epithelium‚ no villi‚ a few glands secreting mucus‚

Nucleic acids • Macromolecules are large molecules (polymers) composed of thousands of covalently connected (monomers). • Everything is made of atoms molecules macromolecules. Macromolecules are polymers‚ built from monomers • A polymer is a long molecule consisting of many similar building blocks. • These small building-block molecules are called monomers. • Three of the four classes of life’s organic molecules are polymers: – Carbohydrates – Proteins – Nucleic acids The
