What else can I help you with?
Can alcohols dissolve fats?
Really depends on the fat and alcohol you are talking about. Alcohol has two ends, hydrophilic end, OH group (water loving) and hydrophobic end (water hating). If the alcohol is long chain molecule with longer hydrophoic end, then probably will be able to dissolve fat better.
Which cell organelle synthesizes the lipids that make up the bulk of cell membranes?
The cell membrane is a lipid bilayer, composed of phopholipids: A glyerol molecule with two fatty-acid groups at one end and a phosphate group at the other.Phospholipids are synthesised in the cytoplasm next to the endoplasmic reticulum. The ER sythesthies the lipids, and contains enzymes that catalyse the production of phopholipids such as Glycerol-3-phosphate acyltransferase. The phospholipids produced migrate naturally to the internal face of the membrane, and flippase moves them to the outer face.
Why is it a good idea to wear rubber gloves when washing dishes?
Because detergent is a phospholipid-like molecule, meaning the the head is hyrophillic (attracted to water) and the tail is hyrdophobic (doesn't like water). Water is highly polar so when you add detergent the heads will attract to the water molecule. However the tails will try to stick to something that isn't water. (like your hands) So when the heads get pulled they pull whatever the tails are attached to aswell, so you'll notice sometimes that your hands become dry. Hope this helped :)
Does orbit gum whiten teeth?
Actually yes it does it has baking soda in it which can whiten teeth. But you have to chew the gum a lot and too much baking soda can damage teeth instead of doing good (I edited the old answer from someone else because it was immature)
Does eclipse gum contain xylitol?
Normal Wrigley's Spearmint Gum does not contain Xylitol. Here are the ingredients:SUGAR, GUM BASE, DEXTROSE, CORN SYRUP; LESS THAN 2% OF: NATURAL AND ARTIFICIAL FLAVORS, GLYEROL, SOY LECITHIN, ASPARTAME, ACESULFAME K, COLORS (YELLOW 5 LAKE, BLUE 1 LAKE), BHT (TO MAINTAIN FRESHNESS). PHENYLKETONURICS: CONTAINS PHENYLALANINE.If you're looking for Xylitol Gum, you should check out www.Xlear.com. They have 100% Xylitol gum that promotes dental health (which I'm guessing is why you are asking about Xylitol gum).You can get a 100-piece package for around $8.http://www.xlear.com/xylitol-gum.aspx
Which type of monomers make up lipids?
Carbohydrates: include sugars and their polymers. They include monosaccharides disaccharides, and polysaccharides. The monosaccharide is a monomer, the disaccharide is a polymer,and the polysaccharides are macromolecules. Monosaccharides: The basic formula (CH2O) Examples: triose sugars, 3 carbons, glyceraldehyde and dihydroxyacetone; pentose sugars. 5 carbons. ribose, deoxyribose, and ribulose; hexose sugars, 6 carbons, glucose, galactose, and fructose. Disaccharides: These are double sugars with the formula C12H22O11. Notice that one molecule of water is missing from the formula. The covalent bond holding the two monomers together is called a 1-4 or 1-2 glycoside linkage. Examples: sucrose = glucose + fructose. maltose = glucose + glucose, and lactose = glucose + galactose. Lipids: A group of polymers that have one characteristic in common, they do not mix with water. They are hydrophobic. Some important groups are fats, phospholipids, and steroids. Fats: are large molecules composed of 2 types of monomers, glycerol ( an alcohol containing 3 carbons) and 3 fatty acid molecules. The bond connecting the glycerol and fatty acids in the fat molecule is called an ester bond. Phospholipids: structurally related to fats but contain 2 fatty acids and one molecule of phosphate. These molecules are found making up the plasma membrane of cells. They exhibit a polar and non polar quality. The phosphate group is hydrophilic while the fatty acid area is hydrophobic. Steroids: Lipids characterized by a carbon skeleton of 4 fused rings. Cholesterol is an important steroid found in all animal tissue. Plants do not contain cholesterol. Cholesterol functions in many ways: it is a precursor from which many of the bodies steroids are constructed from. It also adds strength to the plasma membrane in animal cells. Proteins: macromolecules that make up 50% of the dry weight of most cells. They are composed of amino acids. There are 20 different amino acids. Each amino acid has an optical isomer. The left amino acid is the functional one. The D- amino acid only rarely function. Proteins are formed by bonding amino acids together. The bond formed is called a peptide bond.
