1. Explain the difference between a peptide bond and a sulfide bond. Draw an example of each. (Insert a picture of your drawing of the molecule or a scan of your drawing of the molecule) A peptide bond is a covalent bond. This bond is between two amino acid molecules. The formation of a peptide bond occurs when a carboxyl group present on one molecule reacts with an amino group that is present on the molecule. This reaction releases H2O. In organic chemistry‚ I learned that a sulfide bond has to

Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in

BACKROUND INFORMATION Organic chemistry is the study of hydrocarbons and their various deviations. (Ex. natural gas‚ paper‚ proteins‚ carbohydrates) Saturated hydrocarbons are hydrocarbons with carbon-carbon single bonds. (Ex. C-C) Unsaturated hydrocarbons are hydrocarbons with one of more multiple carbon-carbon bonds. (Ex. C=C double bond‚ triple bond‚ or both) Stereoisomers have the same molecular and structural formulas but different orientations of atoms in space. Constitutional isomers

lactose‚ maltose and sucrose. Oligosaccharides - These are complex carbohydrates that consist of three to ten sugars. They are rich in vitamins and minerals; and‚ because they are fiber-rich‚ they are slower to digest than a simple carbohydrate. Polysaccharides - These are also complex carbohydratges and are rich in vitamins‚ minerals and fiber; but‚ they have larger numbers of sugars than an oligosaccharide.

Carbohydrates are classified by their number of sugar units: monosaccharides (such as glucose and fructose)‚ disaccharides (such as sucrose and lactose)‚ and polysaccharides (such as starch‚ glycogen‚ and cellulose).

Flowering plants grow in a wide variety of habitats and environments. They can go from germination of a seed to a mature plant producing new seeds in as little as a month or as long as 150 years. Plants that complete their life cycle in a single season are called annuals; while biennials take two years; and perennials may take several to many years to go from germinated seed to producing new seeds. Fruits and Seeds The taste of a fruit depends on the combinations present in it. Normally
