Integral protein - A membrane protein that cannot be easily removed from the lipid bilayer. Adaptation: microenvironments of the host body provide habitats for bacteria that are capable of selective tissue invasion (e.g. CallUrl('bioq>biology>leidenuniv>nlhtml',0), ~TildeLink(): describes a substance that dissolves in water; water-lovinghydrophobic: describes a substance that does not dissolve in water; water-fearinglitmus paper: filter paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator ... CallUrl('opentextbc>cacomontrack-media>nethtml',1), Phospholipids are characteristically ~TildeLink() ("water-loving") at their phosphate ends and hydrophobic ("water-fearing") along their lipid tail regions. 2.3.3 Hydrophilic membranes and coatings. Hydrophilic substances diffuse in water, which is to say they move from areas of high concentration to areas of low concentration. In biology, many substances are hydrophilic, which allows them to be dispersed throughout a cell or organism. Everything you always wanted to know. Water fearing/repelling. ; A hydrophobic colloid, or emulsion, is defined as a colloid system where the particles are hydrophobic polymers. These structures are able to encapsulate the aqueous solutes. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The tails bump up against each other and the heads are out facing the watery area surrounding the cell. A hydrophilic colloid, or hydrocolloid, is defined as a colloid system in which the colloid particles are hydrophilic polymers dispersed in water. Biology Forums - Study Force is the leading provider of online homework help for college and high school students. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins. Hydrophobic compounds do not dissolve easily in water, and are usually non-polar. All of the other answers use lots of words but no pictures. In general, hydrophilic describes things that … Molecules that have charged parts to them are attracted to the charges within the water molecule. hydrophobic: [ hi″dro-fo´bik ] 1. repelling water; insoluble in water; not readily absorbing water. A hydrophilic molecule or substance is attracted to water. This is caused by the attraction of water molecules to the hydrophilic molecules. CallUrl('www>talkorigins>orghtml',0), Capsules: Some bacteria produce ~TildeLink() gels that inhibit phagocytosis (e.g. The twin extensions represent the fatty acid components which are not water soluble (hydrophobic).
