Lipids Flashcards
What are the main types of lipids?
Saturated fats, unsaturated fats, oils, waxes
Lipids are categorized into these types based on their structure and properties.
What is a characteristic property of lipids regarding water?
They won’t mix with water
This hydrophobic nature is a defining characteristic of lipids.
What are the primary elements that make up lipids?
Carbon, hydrogen, and oxygen
Lipids are primarily composed of these elements but have a lower proportion of oxygen compared to carbohydrates.
How do lipids generally feel to the touch?
Greasy, oily, or waxy
This tactile quality is common among various types of lipids.
What state are fats typically in at room temperature?
Solid
Fats are solid at typical room temperatures (70°-72°F).
What state are oils typically in at room temperature?
Liquid
Oils are generally liquid at room temperature and are primarily derived from plants.
What are the two categories of fats based on saturation?
Saturated fats and unsaturated fats
This classification is based on the presence of double bonds in the carbon chain.
What distinguishes saturated fats from unsaturated fats?
Saturated fats have no double bonds between carbon atoms
Unsaturated fats contain at least one double bond.
Which type of fats are typically considered harmful?
Saturated fats
Animal fats are often saturated and can be harmful to health.
What type of oils are considered beneficial?
Unsaturated oils
Examples include plant oils, which are generally healthier.
What is the healthiest oil mentioned?
Olive oil
Olive oil is often recommended for its health benefits.
What process converts unsaturated fats to saturated fats?
Hydrogenation
This process involves adding hydrogen to unsaturated fats, making them more solid.
Fill in the blank: Waxes are typically _______ at room temperature.
Solid
Waxes, like other lipids, remain solid at room temperature.
